I'm most grateful to all those who identified this caterpillar.
Deilephila Elpenor, known as the Elephant Hawk-moth, is a large moth of the family Sphingidae The species is found throughout Britain and Ireland. Its range extends across Europe, Russia, and into China, northern parts of the Indian subcontinent, Japan and Korea (though not Taiwan). Introduced specimens have been found in British Columbia. In most of their range, the adults are seen from May to July and the caterpillars from July to September, when they pupate. However, in some parts of the Mediterranean and China the adults may be seen from April on, sometimes having two broods in a year. The larva is about 75 millimetres (3.0 in) long, green and brown in colour. Like most hawk moth caterpillars, they have a backward curving spine or "horn" on the final abdominal segment. The anterior of the caterpillar appears to have the shape of a trunk-like snout. It is this elephant look, rather than its large size, that gives the moth its name. When startled, the caterpillar draws its trunk into its foremost body segment. This posture resembles a snake with a large head and four large eye-like patches. Caterpillars are preyed upon by birds, but these shy away (at least for some time) from caterpillars in "snake" pose. It is not known whether the birds take the caterpillar to actually resemble a snake, or are frightened by the sudden change of a familiar prey item into an unusual and boldly-patterned shape. The preferred food plants of the caterpillar are willowherb (Epilobium) and bedstraw (Galium), though it will also take fuchsias. The moth typically has a wing span of 50–70 mm (2.0–2.8 in). The upper side ground colour of head, thorax and abdomen is khaki, excepting the pink inner edges and median line of the tegulae, posterior margin of thorax, base of abdomen, abdominal median line and terminal abdominal segments. The upper side of forewing is also khaki, except the pink costa, a pink narrow, median band extending from the inner margin to Medial vein 3, a pink and narrow postmedian band which extends from the inner margin to the apex, and a pink marginal band.The basal half of the hindwing upperside is black, distal half pink (the distal edge of black area is almost straight and parallel to the outer margin). f. unicolor Tutt, has no pink coloration on the forewing
The imago (adult) feeds at night, and often takes nectar from garden plants like Honeysuckles (Lonicera) and petunias, so it is quite often seen in urban settings in the evening. It is spectacularly coloured, seeming to shimmer with green and red when in motion. The adult moths are eaten by some species of bats. This species possesses good night or scotopic vision. Its eye includes two different kinds of ommatidium; each contains nine light sensitive cells, of which seven contain a pigment whose absorption spectrum peaks in the green part of the spectrum, but in one type the remaining two receptors have peak absorption in the blue and in the other type they have peak reception in the ultra violet. The moth therefore has the cellular prerequisites for trichromatic colour vision. Adults have been shown to be capable of making colour discriminations at night-time levels of illumination, and they sustain these discriminations despite changes in the spectral content of the incident light; that is, they show colour constancy. Two subspecies, Deilephila elpenor elpenor and Deilephila elpenor lewisii, were recognised in the past, but they are no longer regarded as well distinguished. Similarly the subspecies Deilephila elpenor szechuana is now thought to be a synonym for Deilephila elpenor elpenor. The subspecies Deilephila elpenor macromera, found in southern China, northern India, Bhutan and Myanmar, is still regarded as distinct.
The related species, the small elephant hawk-moth Deilephila porcellus and Chitral elephant hawk-moth Deilephila rivularis are similar but smaller and less colourful.

After the final vanquish of the supporting palm tree and the trunks absorption, the old, mature tropical Strangler Fig tree can become very majestic and very very big and spreading. This otherwise topheavy tree benefits from the well engineered butresses, keeping it stable in high winds. Also very noble and beautiful! Behold, the conqueror, surveying it's empire. The tree can become very noisy with the chatter of flocks of birds eating the fruit. This is NOT the fig tree of Fig Newton fame. This is a Killer Fig Tree. Compare to the youth in the prior image where the supporting palm tree remains alive.........for a while longer. This image is of the old veteran.

• Bees are vital to the preservation of ecological balance and biodiversity in nature. They provide one of the most recognizable ecosystem services, pollination, which is what makes most food production possible.
• One third of all the food we eat depends on bees, and of the 100 crop varieties that provide 90% of the world’s food, 71 are pollinated by bees.
• Honeybees alone pollinate 80% of all flowering plants, including more than 130 types of fruits and vegetables.
• The journey of bees begins with manure and fertilizer. It is used to enrich the soil, providing essential nutrients that help seeds germinate and plants grow.
• Water, a fundamental element for life, aids in the absorption of these nutrients from the soil, allowing the plant to grow strong and healthy.
• As the plant matures on the fertile land, it develops vibrant flowers rich in nectar and pollen.
• Bees are attracted to these flowers for their nectar, which they use to create honey, and in the process, they pollinate the plant, contributing to its reproductive cycle and the growth of new plants.
• This illustrates a symbiotic relationship, where bees and plants rely on each other for survival and growth.
• Despite their profound importance for the food we eat, bee populations are declining at an alarming rate.
• Last winter, Canada had its largest honeybee colony loss in the past 20 years, with 46% of colonies perishing nationally.

Casa Cavassa, a refined Renaissance residence in the historic heart of Saluzzo, was transformed in the late 15th century by Marquis Michele Antonio di Saluzzo into an elegant urban palace blending medieval structure with Renaissance elegance. Today home to the Civic Museum Casa Cavassa, it preserves original frescoes, stuccoes, and period furnishings, offering a rare glimpse into the domestic life and artistic tastes of the noble elite in the Marquisate of Saluzzo. Its harmonious courtyard and richly decorated interiors reflect the cultural flourishing of this independent Piedmontese state before its absorption into the Duchy of Savoy.

Character Creation
Ursa is a supervillain appearing in American comic books published by DC Comics. She first appeared in the 1978 film Superman: The Movie portrayed by actress Sarah Douglas.
The character made her comic book debut in Action Comics #845 (January 2007). An adversary of the superhero Superman, Ursa is the wife and lieutenant of General Zod. She is typically depicted as having been imprisoned in the Phantom Zone along with Zod and Non.
Fictional Character History
History (New Earth) -Last Son (Part II)
The Kryptonian Science Council discovered that two of their most revered scientists, Jor-El and Non, had determined that in a short matter of time, Krypton would suffer geothermic upheavel that would destroy the entire planet. Branding them as heretics, the cowardly members of the Science Council sent General Zod and his militants to Jor-El's laboratory to arrest he and Non.
Ursa was in charge of placing the two scientists under arrest and handing them over to the council. The Science Council administered a stern warning to them, and set them free. Before long, Zod and Ursa discovered that Jor-El and Non had been right all along. Krypton had little time left.
Non ignored the Council's warning and preached to the populace of Krypton revealing everything he knew of the pending disaster. Zod and Ursa defected from the military and joined Non's cause. Soon after, Non was captured and lobotomized under orders of the Science Council.
This incident drove Zod over the edge, and Ursa and he began an insurrection that made them the most wanted criminals on the planet. They were eventually captured and brought to justice. Jor-El argued on their behalf, and swayed the Science Council from sentencing them to death. Instead, Jor-El elected for a more peaceful means of punishment - exile in the Phantom Zone.
Rebirth (Prime Earth) -Revenge Conclusion
During Cyborg Superman's plans on forming a team to take revenge on Superman, he recruits General Zod.
However, most of the team doesn't want Zod as there leader, Zod then betrays them and sends the Eradicator II and Cyborg Superman into the Phantom Zone. Henry Henshaw thinks they are there to retrieve Zod's army, but instead the Eradicator is given orders by Zod to rescue his wife Ursa and there son Lor-Zod, which was his goal all along. With the Eradicator, they escape and fled to another planet, Jekuul, to help begin Zod's plans on rebuilding a new Krypton. Cyborg Superman is left trapped in the Phantom Zone.
Powers & Abilities
Military Training
As a member of the Kryptonian Military Guild, she received extensive training in the use of weapons, applicable technology, hand to hand combat, strategy, and survival techniques.
As a Kryptonian, Ursa is as dangerous as she is beautiful. Under the yellow sun, she has all of Superman's powers and abilities: flight, super-strength, speed, heat-vision, and others to mention, are all apart of her power set.
She's absolutely loyal to Zod and is willing to do absolutely anything for him. Her fighting skills are extremely deadly, making her a foe that Superman or other superheroes need to watch out for.
Kryptonian Physiology
Under the effects of a "yellow" sun, Ursa possesses the same potential powers as an average Kryptonian. These include:
Solar Energy Absorption
Under optimal conditions, this is the main source of Ursa's super powers as they are contingent upon exposure to solar radiation from a yellow sun star system.
Her biological make up includes a number of organs which lack analogues in humans and whose functions are unknown.
It is believed that between one or more of these and her bio-cellular matrix, "yellow" solar energy is stored for later use.
This allows for the use of these powers to fade when yellow solar radiation is not available instead of immediate failure.
Heat Vision
Ursa can, as a conscious act, fire beams of intense heat at a target by looking at it. She can vary the heat and area affected.
Super-Hearing
Ursa's hearing is sensitive enough to hear any sound at any volume or pitch. With skill and concentration, she can block out ambient sounds to focus on a specific source or frequency.
Enhanced Vision
Ursa's vision processes the entire electromagnetic spectrum as well as allowing vast control over selective perception and focus.
This umbrella ability includes the following:
Electromagnetic Spectrum Vision
Ursa can see well into most of the electromagnetic spectrum. She can see and identify radio and television signals as well as all other broadcast or transmitted frequencies. Using this ability, she can avoid detection by radar or satellite monitoring methods. This also allows her to see the aura generated by living thing.
Telescopic Vision
This is the ability to see something at a great distance, without violating the laws of physics. Though limited, the exact extent of the ability is undetermined. In function, it is similar to the zoom lens on a camera.
X-Ray Vision
This is the ability to see through any volume of matter except lead. Ursa's can see things behind a solid, opaque object as if it were not there. She can focus this ability to "peel back" layers of an object, allowing hidden image or inner workings to be observed. The exact type of energy perceived - such as x-rays, cosmic rays, or some other energy invisible to normal humans - is unclear. This ability perceives an ambient energy source though, it does not involve the eye projecting a concentrated, possibly toxic, beam to be reflected back from objects.
Microscopic Vision
This is the ability to see extremely small objects and images down to the atomic level.
Infrared Vision: Ursa's can see with better acuity in darkness, and to a degree in total darkness.
Flight
Ursa is able to manipulate graviton particles to defy the forces of gravity and achieve flight. This ranges from hovering to moving in any posture, in any direction.
Invulnerability
Due to the interaction of her dense molecular structure and supercharged bio-electric aura, Ursa is nigh-invulnerable to extreme energy forces. In addition, her extends this protection against toxins and diseases.
Superhuman Stamina
Ursa is able to maintain continuous strenuous physical action for an indefinite period of time. This based on her body converting yellow solar radiation directly to energy, but is limited by physiological and psychological needs to eat, drink, and sleep.
Superhuman Strength
Ursa's strength is augmented by yellow solar radiation interacting with the greater than human density, resilience and biological efficiency of her musculature. Her strength is more an act of conscious will on energy fields than actual physical strength. It is this act of conscious will that enables her to perform physical feats that are beyond the mere application force, such as moving a mountain top without said rock crumbling under its own mass.
Superhuman Speed
Ursa is able to move at incredible speed by sheer force of will. This extends to her perceptions and allows for feats such as catching bullets in mid flight as well as covering vast distances in little or no time.
This also confers:
Superhuman Agility
Superhuman Reflexes
Super-Breath
Ursa is able to create hurricane force winds by exhaling air from her lungs. She can chill the air as it leaves her lungs to freeze targets. She can also reverse the process to pull large volumes of air or vapor into her lungs.
Weaknesses
Kryptonian Physiology
Under the effects of a "yellow" sun, Ursa possesses the same potential weaknesses as an average Kryptonian. These include:
Vulnerability to Kryptonite
Vulnerability to Magic
Solar Energy Dependancy

Here is Nickle Plate Road 83000 still looking quite nice long after the railroad's absorption into the Norfolk & Western in 1964. The N&W had similar cars to this one, also built by Greenville Steel Car which were classed B19s. I'm not sure if these exNKP cars were folded into this class or given their own designation. This car was photographed at Collinwood Ohio on April 9th, 1977 by Eric Hirsimaki.
Tirumala limniace, the blue tiger, is a butterfly found in South Asia and Southeast Asia that belongs to the crows and tigers, that is, the danaid group of the brush-footed butterfly family. This butterfly shows gregarious migratory behaviour in southern India.In general, all butterflies can directly absorb heat from the sun via their wings to facilitate autonomous flight. Studies on blue tiger butterflies show that high-intensity light significantly increased flight activity. Blue tiger butterflies have a wing surface color that is composed of both light and dark colors. The dark areas on the wing surfaces are the heat absorption areas that allow for the facilitation of autonomous flight.
Por su aspecto y los ojos dicópticos (separados) y larga probóscide se trata de un ejemplar hembra de Pangonius sp. (Familia Tabanidae). Gracias al amigo Henrik Gyurkovics por la identificación. Con esa poderosa trompa succionadora llevan a cabo la abosorción de néctar y ocasionalmente sus picaduras un tanto dolorosas.
Due to its appearance and dicoptic eyes (separated) and a long proboscis, it is a female specimen of Pangonius sp. (Family Tabanidae). Thanks to friend Henrik Gyurkovics for the identification. With that powerful sucking tube they carry out the absorption of nectar and occasionally their somewhat painful stings.

Truncated version of a Student Keeling graph - CO2 in the atmosphere from 1958 to present, showing seasonal variation, using data collected at Mauna Loa, Hawai`i.
[If you are a teacher and you decide to use this idea, please let me know. You can contact me for files with grids for graphing, and for charts of the data from 1958 to present.]
In 1958 Charles David Keeling set up a carbon dioxide testing station on Mauna Loa, on the Big Island of Hawai`i. Data has been collected there over the past 5 decades. Here's the web page for the CO2 program. The data can be found here. Remember that -99.99 means missing data.
WHOAAA!! CHECK OUT THE NEW DATA PAGE!!!
The photo above shows part of a graph my 8th graders put together this year. The vertical scale of the graph paper ranges from 310 to 390 ppm CO2. Each class did a graph. Each group did one sheet. Each sheet held 4 years of data. I invite other teachers to do the same exercise!! Let me know how it went.
Each student graphed at least 2 years of data. Some did more for extra credit. Once they had finished their sheet, I had them cut off one end and we overlapped the other end to make this composite graph. Sadly, all got discarded at the end of the year except this one, and this one ranges only from 1958 to 1992. The rest of the classes went all the way to 3/08, and contained 4 more sheets.
So, what's the trend of CO2 in the atmosphere over the last 50 years?
The curvy line indicates the monthly data, with seasonal fluctuations. The red line is a student group's approximation of the general trend of the data. The data itself ranged from about 314 to 386 ppm, from 1958 to 2008, or an increase of approximately 70 ppm. Starting at 314, and increasing by 70 ppm is an increase of 22% .......
TWENTY TWO PERCENT INCREASE IN THE CO2 CONTENT OF THE ATMOSPHERE IN THE PAST 50 YEARS!! That's an increase by more than one fifth! And that was in 2008.
So what? Well let's ignore the global warming issue for a moment. One of the less-discussed results of CO2 in the atmosphere is that it dissolves into the oceans, and forms carbonic acid [a small amount of the CO2 combines with water to form a small amount of H2CO3 in the solution], so this trend in atmospheric CO2 also points toward acidification of the oceans. Scientists have been investigating how this might affect the marine ecosystems, especially the near-surface waters, where the atmospheric gas absorption occurs.
Well, guess what? One thing that an acid can do is dissolve things like calcium carbonate, or reduce the rate of calcification. Now, CaCO3 [thanks phyto] just happens to be the primary ingredient of the shells and casings of various marine organisms, such as clams, oysters, snails/gastropods, corals, and many planktonic organisms such as calcareous algaes. But see the first link in phyto's comment below that indicates some organisms are actually producing CaCO3 at an increasing rate. (see, for example, this article.) So, if some ecologically important organisms (what organisms aren't ecologically important?) find it progressively more difficult to form shells and casings, then what?
Maybe we're being forced to find out. Over the past few years events have occurred where oyster larvae in the Pacific Northwest were dying prematurely. The cause was ultimately traced to pH fluctuations. Now the oyster production process must be adjusted to accommodate these fluctuations -- an adaptation that will only be effective as long as the high pH periods are not too acidic.
Really beautiful object catalogued as 881 on the Lynds' Catalogue of Dark Nebulae.
It's one of the jewels that you could find on gamma Cygni nebula, on SADR region of Cygnus, one of my favorites regions of the sky.
"A dark nebula or absorption nebula is a type of interstellar cloud that is so dense that it obscures the visible wavelengths of light from objects behind it, such as background stars and emission or reflection nebulae. The extinction of the light is caused by interstellar dust grains located in the coldest, densest parts of larger molecular clouds." (wiki)

This spider on Sundew has been reworked ..
This is a member of a type of plant referred to as insectivorous that is a plant that gets it's nutrients from the trapping /capturing / extraction and absorption of insects that are attracted to the plant either for dew drops or nectar like substance.In the case of this plant the sapphire coloured sticky tentacles are tipped with a small jewel like drop of dew to which the insect is fatally attracted they almost always become stuck and the tentacles rapidly coil around the insect as does the delicate( 3mm across) frond the unfortunate insect is doomed from then on and is slowly consumed over a period of days macabrely it is still alive for most of that time.This tiny little spider you see here is a form of money spider of which there are many and is perfectly safe on this side of the frond being the non sticky side it appears to be taking advantage of the Sundews ability to attract insects.You often do see a variety of spiders living among all types of insectivorous plants so it must be worth it..

What do leaves and solar panels have in common?
Both absorb sunlight and turn it into energy. But while solar panels typically have smooth surfaces, leaves have tiny wrinkles and folds that allow for maximum light absorption.

The Gordon River rises below Mount Hobhouse in the Franklin-Gordon Wild Rivers National Park draining the eastern slopes of the King William Range. The river flows generally south and to the west of the Gordon Range before flowing west through the Gordon Gap and spilling into Lake Gordon, an impounded reservoir created by damming the Gordon at the Gordon Dam. Together with water fed from Lake Pedder, the principal purpose of the reservoir is for generation of hydro-electricity at the Gordon Power Station.
Flowing from east to west through Lake Gordon, the river continues west, passing through the Gordon Splits, a series of gorges once considered impassable until 1958 when Olegas Truchanas, a conservationist and nature photographer, was the first person to navigate the Gordon River in a kayak. The river flows north by west and then due north and finally due west as it reaches its mouth and empties into Macquarie Harbour at Wrights Bay.
From source to mouth, the river is joined by 25 tributaries including the Gell, Boyes, Pokana, Holley, Adams, Serpentine, Albert, Orange, Smith, Denison, Olga, Sprent, Franklin, and the Spence rivers.
The river descends 570 metres (1,870 ft) over its 172-kilometre (107 mi) course;[1] much of which is located in an uninhabited wilderness area, contained with the Franklin-Gordon Wild Rivers National Park and Southwest National Park. The lower part of the Gordon River is part of the Tasmanian Wilderness World Heritage Area and contains a cold-climate rainforest and rare trees. As with many rivers in western Tasmania, the water is fresh and drinkable, yet has the colour of weak tea due to the absorption of tannin from button grass growing in the catchment area.
Additional dams were proposed for the lower part of the river. However, these plans were changed as a result of significant opposition and public opinion. In particular, the Franklin Dam was proposed just downstream of the junction with the Franklin River, and would have flooded much of both rivers. It was a major political and environmental issue in the 1980s.
Boat excursions to the lower Gordon River from Macquarie Harbour are popular with tourists in Strahan. Seaplane flights depart Strahan during the warmer months and include an out landing on the Gordon River
Why do Zebras have black and white stripes? There have been many theories. Dazzle camouflage, making it difficult for lions to visually isolate a single animal from the herd. More recently, focus has been on the relationship with tsetse flies that probably kill more zebras than lions. I had originally heard that the black and white stripes create weather at the surface of their skin, via differential heat absorption and reflection that in turn create turbulence, and hence make flight difficult for tsetse and horse flies. However, the latest, and most robust theory comes from Tim Caro, whom I was lucky enough to spend some time with at the San Diego Zoo this summer. Tim, and his team at UC Davis have shown that the stripes disrupt the flies vision, making it hard for them to land and bite. Sometimes evolution moves in unobvious ways.

Messier 20 (NGC 6514) The Trifid Nebula
Named for its 3 lobe appearance and located in Sagitarius this stellar nursery is approximatly 5200 light years away it is one of the youngest emission nebula, estimated to be about 300,000 years old.
A group of recently formed, massive, bright stars toward the centre of the nebula are easily visible. These stars are releasing a flood of ultraviolet radiation that dramatically influences the structure and evolution of the surrounding nebula. Star formation is no longer occurring in the immediate vicinity of this group of bright stars because their intense radiation has blown away the gas and dust from which new stars are made.
The nebula measures 10 light years across and is a wonderful example of the three most common nebula consisting of an emission nebula (red, pinkish region) reflection nebula (blue region) and absorption nebula (dark region) making it a favourite target for astrophotographers
It can be observed with nothing more than a pair of binoculars, but a good scope will reveal some of the intricate detail to be found here.

Jumping spiders have very good vision centered in their anterior median eyes (AME). Their eyes are able to create a focused image on the retina, which has up to four layers of receptor cells in it. Physiological experiments have shown that they may have up to four different kinds of receptor cells, with different absorption spectra, giving them the possibility of up to tetrachromatic color vision, with sensitivity extending into the ultra-violet range. It seems that all salticids, regardless of whether they have two, three or four kinds of color receptors, are highly sensitive to UV light. Some species (for example, Cosmophasis umbratica) are highly dimorphic in the UV spectrum, suggesting a role in sexual signaling. Color discrimination has been demonstrated in behavioral experiments.
The principal eyes have high resolution (11 min. visual angle), but the field of vision is narrow, from 2-5 degrees.
Because the retina is the darkest part of the eye and it moves around, one can sometimes look into the eye of a jumping spider and see it changing color. When it is darkest, you are looking into its retina and the spider is looking straight at you.

• Bees are vital to the preservation of ecological balance and biodiversity in nature. They provide one of the most recognizable ecosystem services, pollination, which is what makes most food production possible.
• One third of all the food we eat depends on bees, and of the 100 crop varieties that provide 90% of the world’s food, 71 are pollinated by bees.
• Honeybees alone pollinate 80% of all flowering plants, including more than 130 types of fruits and vegetables.
• The journey of bees begins with manure and fertilizer. It is used to enrich the soil, providing essential nutrients that help seeds germinate and plants grow.
• Water, a fundamental element for life, aids in the absorption of these nutrients from the soil, allowing the plant to grow strong and healthy.
• As the plant matures on the fertile land, it develops vibrant flowers rich in nectar and pollen.
• Bees are attracted to these flowers for their nectar, which they use to create honey, and in the process, they pollinate the plant, contributing to its reproductive cycle and the growth of new plants.
• This illustrates a symbiotic relationship, where bees and plants rely on each other for survival and growth.
• Despite their profound importance for the food we eat, bee populations are declining at an alarming rate.
• Last winter, Canada had its largest honeybee colony loss in the past 20 years, with 46% of colonies perishing nationally.
• Global warming, pesticide use, habitat destruction, and air pollution all contribute to bee mortality.
• By understanding the vital role bees play in our ecosystem and food production, and making conscious choices to help, we can contribute to the conservation of bees and the vital services they provide.
Too much water, caused by excessive watering or heavy rain, can lead to a plant wilting. Overly saturated soil can make it harder for plant roots to absorb water, because they do not have the oxygen they need for absorption. ... Root rot and other fungal diseases fostered by a wet environment can also cause wilting.
Casa Cavassa, a refined Renaissance residence in the historic heart of Saluzzo, was transformed in the late 15th century by Marquis Michele Antonio di Saluzzo into an elegant urban palace blending medieval structure with Renaissance elegance. Today home to the Civic Museum Casa Cavassa, it preserves original frescoes, stuccoes, and period furnishings, offering a rare glimpse into the domestic life and artistic tastes of the noble elite in the Marquisate of Saluzzo. Its harmonious courtyard and richly decorated interiors reflect the cultural flourishing of this independent Piedmontese state before its absorption into the Duchy of Savoy.
Give up your selfishness, and you shall find peace; like water mingling with water, you shall merge in absorption.

This was a fairly tough object to process. I took this over 2 nights (7th & 8th Dec) with the moon up and between 70-80% illumination which did affect the subs especially the Oiii. I was going to rotate this but I think it looks better on its side.
Note:-
1. I add the Ha stars back in near the end of the process, given me smaller stars and no colour Halo's....
2. This is not true Hubble as it only made up of Ha & Oiii data
Information:-
NGC 2264 designation refers to both the Christmas Tree Cluster and the Cone Nebula. The cone's shape comes from a dark absorption nebula consisting of cold molecular hydrogen and the dust in front of a faint emission nebula containing hydrogen ionized by S Monocerotis, the brightest star of NGC 2264.The nebula is located about 2,700 light-years away from Earth.

This star-studded image from NASA's Hubble Space Telescope depicts globular cluster NGC 6717, which lies more than 20,000 light-years from Earth in the constellation Sagittarius. Globular clusters are roughly spherical collections of stars tightly bound together by gravity.
The bright foreground stars at the center of the image reside between Earth and the cluster, and are distinguished by the crisscross diffraction spikes that form when their light interacts with the structures supporting Hubble’s secondary mirror.
The constellation Sagittarius is in the same area of the night sky as the center of the Milky Way, which is filled with light-absorbing gas and dust. This absorption of light – which astronomers call “extinction” – makes studying globular clusters near the galactic center challenging. To determine the properties of NGC 6717, astronomers relied on a combination of Hubble’s Wide Field Camera 3 and the Advanced Camera for Surveys.

Typically leaves are flat and thin, thereby maximising the surface area directly exposed to light and promoting photosynthetic function. Externally they commonly are arranged on the plant in such ways as to expose their surfaces to light as efficiently as possible without shading each other, but there are many exceptions and complications; for instance plants adapted to windy conditions may have pendent leaves, such as in many willows and Eucalyptus.
Likewise, the internal organisation of most kinds of leaves has evolved to maximise exposure of the photosynthetic organelles, the chloroplasts, to light and to increase the absorption of carbon dioxide. Most leaves have stomata, which open or narrow to regulate the exchange of carbon dioxide, oxygen, and water vapour with the atmosphere.

Another shot from Belur. The rains had just stopped and a passage of light ...lucky to
get a patch of blue n shades of white in the sky. THE LEFT section is at a higher level than the right, dry except for the floor and has a roof ...the light/color absorption is different. Same WB settings across.
DRI- Handheld. 3 different exposures. with spot focus on the pillar for one exposure and 2 others between the left flank wall and the right section - sky. I had to hold the cam steady with one hand and move the cursor to specific spots...aligned in PS. Individual exposures treated in ACR.

Messier 52 (also known as NGC 7654) is an open cluster in the Cassiopeia constellation. It was discovered by Charles Messier in 1774. M52 can be seen from Earth with binoculars.
Due to interstellar absorption of light, the distance to M 52 is uncertain, with estimates ranging between 3,000 and 7,000 light years. One study identified 193 probable members of the cluster, with the brightest member being magnitude 11. (text: en.wikipedia.org/wiki/Messier_52)

Today is a critically important day: Ukrainian Independence Day. The modern, democratic, free nation of Ukraine was born on August 24th, 1991 with the signing of their Declaration of Independence. It also marks exactly six months since the start of the all-out invasion from Russia.
A while back, knowing that this existential conflict was likely to last a long time, I ordered some sunflower seeds. Not your average variety, mind you, this is a special “white sunflower”, a cultivar known as “ProCut White”. Years ago, I was given a tip that white sunflowers are some of the most beautifully fluorescent; This tip has just been proven correct. While the pollen of that particular species does not seem to fluoresce, the petals certainly put on a light show!
I have seen “electric blue” lines in some flower petals before (snowdrops), but the two-tone colours of the petals themselves is something I’ve only observed in flowers directly related to sunflowers. The reason for these fluorescent colours is simply a byproduct of the method for which the flowers absorb UV light. Sunflowers have a “black” center, including half the petals, and bright white external portions of the petals when observed in UV light directly – which many pollinators can see. And there are two ways for a flower to appear “black” in UV: direct absorption, or fluorescence into the visible spectrum, such that the UV light becomes lower-energy visible light. That’s the science behind these “by-product” colours, but then also happen to match very closely to the national colours of Ukraine.
In support of Ukraine’s continued battle, I place this image into the Public Domain. It’s currently my phone’s lock screen image, and you may wish to do them same. Use it for anything you’d like, personal or commercial. Spread it far and wide.
Today is also an ominous day. There is word that Russia has closed its airspace in the western-most territories in anticipation of some event today. Kyiv has placed restrictions on mass gatherings. It would be very symbolic for Russia to attempt something horrific today, and I sincerely hope nothing materializes. We’ve seen a few missiles launched, but that’s sadly an every-day occurrence. Russia’s forces continue to be decimated, so any escalation could have some level of desperation associated with it.
In Russia, the middle-class are finally afraid. They fear restrictions on their travel to other countries, and they fear direct attacks on their homes in places like Crimea, which they have been fleeing after Ukraine has made a number of successful attacks in the occupied region. The Russian elites no longer feel safe either, after the car bombing in Moscow that took the life of Darya Dugin, a philosopher and political theorist who was very much in support of Putin’s actions. Her father, Alexander Dugin, is one of Putin’s top ideologists. It sends a very clear message: regardless of social class, you are not completely safe. This fear can become a powerful threat to Putin’s regime, if it can be escalated properly. Increasingly, it appears that Ukraine is holding all the cards, but they still need more help.
Slovakia is sending 30 T-72 tanks to Ukraine after Germany agreed to send them 15 modern Leopard II tanks. New aid packages from many countries including Canada, Sweden, and the United States have been announced. There are reports that Saudi Arabia is returning the Grim-2 missile systems it purchased from Ukraine, some of the most modern long-range systems in existence. The range here is the critical factor: 500km maximum range. The distance between Ukrainian controlled territory in the North, say Hrem’yach, directly to The Kremlin in Moscow, is 473 kilometers.
If Ukraine does indeed have the Grim-2 system, with the longest-range ammunition, they could be in striking distance of Moscow. Would taking such action be a smart move? I don’t think so. However, the possibility alone can bring a layer of much-needed fear to Russia. The hubris cultivated from previous imperialistic gains is eroding. Ukraine will win this war, thanks to the world coming to its aide. It’s far from over yet, as the area controlled by Russia is larger than the majority of nations in Europe.
The fight continues, and today should be a day to celebrate the heroes of Ukraine, both past and present. Show your support!
And on a personal note, I have discovered that I have living relatives in Ukraine. Specifically, my paternal great-grandfather’s cousin who still carries the same last name (it changed a bit when my ancestors emigrated from Ukraine, the original is Komarychko). Likely due to some people having children later in life, his generation has all but disappeared. Soon I hope to have a conversation with him via a translator, and eventually visit the village at the center of my Ukrainian roots where he still lives.
Iron deficiency, or sideropenia, is the state in which a body lacks enough iron to supply its needs. Iron is present in all cells in the human body and has several vital functions, such as carrying oxygen to the tissues from the lungs as a key component of the hemoglobin protein, acting as a transport medium for electrons within the cells in the form of cytochromes, and facilitating oxygen enzyme reactions in various tissues. Too little iron can interfere with these vital functions and lead to morbidity and death.[1]
Total body iron averages approximately 3.8 g in men and 2.3 g in women. In blood plasma, iron is carried tightly bound to the protein transferrin. There are several mechanisms that control iron metabolism and safeguard against iron deficiency. The main regulatory mechanism is situated in the gastrointestinal tract. The majority of iron absorption occurs in the duodenum, the first section of the small intestine. A number of dietary factors may affect iron absorption. When loss of iron is not sufficiently compensated by intake of iron from the diet, a state of iron deficiency develops over time. When this state is uncorrected, it leads to iron-deficiency anemia, a common type of anemia.[1] Before anemia occurs, the medical condition of iron deficiency without anemia is called latent iron deficiency (LID).
Anemia is a condition characterized by inadequate red blood cells (erythrocytes) or hemoglobin. When the body lacks sufficient amounts of iron, production of the protein hemoglobin is reduced. Hemoglobin binds to oxygen, enabling red blood cells to supply oxygenated blood throughout the body. Women of child-bearing age,[2] children, and people with poor diet are most susceptible to the disease. Most cases of iron-deficiency anemia are mild, but if not treated can cause problems like an irregular heartbeat, pregnancy complications, and delayed growth in infants and children that could affect their cognitive development and their behavior.[3]
Taconite has a lot of Iron. Eat a lot of taconite.
Though Blondin's claim that he was a direct descendent of Charles Blondin was a little dubious. That they had grown up in the same Pas-de-Calais region of France did give some credence to the claim, that absorption of the same air, earth and water, fed by the bodies of their collected common ancestors, that mountain of DNA, of mulch.

I hadn't intended to produce a second example of Sunderland District's HUP-C Leyland Leopards, but a simple swap of front panels enabled Northern's CCD 714D to be presented as HUP 947C. This is how it appears (without the lower grille originaly fitted) on page 45 of 'Northern General and its Subsidiaries - From No Place to Success' (Autobus Review Publications). To quote from the caption to that image:
"New to Sunderland District in 1965 and fitted with BET-style dual-purpose bodywork, Leyland Leopard 347 (347 HUPC) is seen here wearing its original light blue and cream, livery. Transferred to Northern upon its absorption of Sunderland District on 1 January 1975, it was repainted into NBC poppy red and renumbered 4304. It was withdrawn in 1978." (08-Feb-10)

This 360° panorama was captured from the Atacama Desert in Chile, one of the most suitable places on Earth for astronomical observation, and more precisely from the European Observatory of "La Silla". Note that the dome in the foreground is the home of the TRAPPIST Telescope, which discovered the famous system of 7-earth-size exoplanets around a red-dwarf star called TRAPPIST-1!)
Anyway, this image not only shows the Milky Way spanning over the entire field of view but also an impressive amount of strange colorful wave-like structures in the whole sky!
This orange/red light emitted at 85 km altitude (and higher) does not originate from artificial light pollution or high altitude clouds.
This rare phenomenon called Airglow is entirely natural and originates from an interaction between the Ultra-violet light of our Sun and the particles of the upper layers of the atmosphere.
During the day, the highly energetic UV light of the sun hits the atoms of oxygen, sodium, nitrogen...etc of the Earth's atmosphere. This absorption of energy puts them in an excited state that only waits for an external process to be able to release this excess of energy.
Using Chemiluminescence, the atoms of the atmosphere are slowly releasing this absorbed UV-llight into visible light, before going back to their stable energy state.
The emission of light, whose color depends on the chemical element involved in the reaction (oxygen for red airglow, sodium for green airglow), continues even during night-time when the sun has set for few hours.
As a fluid, Airglow follows the air flow of the atmosphere and the variation of gravity field caused by the topography of the ground, which produces the so-called "gravity waves" (not gravitational waves!).
These gravity waves are what make the main spatial feature of airglow in the sky: wave-like and ripple-like structures, with strong inhomogeneities.
Red and orange airglow (even a little bit of green) were very strong during that night in Chile! Even though this natural phenomenon is very common in this region of the world, it is usually not as intense as it was during that night!
You can also spot the zodiacal light, a tilted cone of blue light starting from the lower horizon and extending to the galactic center.
This leads to a new definition of what a high-quality sky for stargazing really is: not a dark-sky but a sky under which the rarest and the dimmest natural phenomena can be seen, revealing the true colors of the sky!
The two photographers next to the TRAPPIST observatory are Norédine and Olivia, two astronomy social enthusiasts of our group of 8 which was chosen by ESO to participate to its #MeeESO event.
The other observatories visible in this image are (from right to left) : the Danish 0.5-meter telescope, the ESO-0.5-meter telescope, the ESO-1.52-meter telescope and finally the tiny illuminated dome in the top horizon is the huge ESO-3.6-meter telescope.
17 images were captured and stitched together to form this 360° panoramic view. Neither photo blending/digital art nor over-exaggerated colors/contrasts. The success of this panorama holds in the fact that I used an ultra wide angle lens : a Sigma 14 mm F/1.8 which enabled me to capture far less images and to spend far less time than if I had used a standard lens (35 mm focal length).

Bridge #150 (Hatter's Bridge) on the Leeds-Liverpool Canal near Salterforth, Lancashire, UK, during the weekend's fog and frost
Hatter's Bridge is so named because Foulridge had a flourishing cottage industry of felt hat making from the 17th century.
(The term "mad as a hatter" comes from the use of mercury in the production of felt hats in the 18th and 19th centuries, where absorption of mercury through the skin can cause neurological disorders.)
