Mainline 803 is an unusual Neoplan N416 integral single decker which had been assembled in Hellaby by importers Carlton PSV in 1988 and operated in the associated SUT fleet in Sheffield.
Following the absorption of the SUT fleet into Mainline it became fleet no 803 and was later transferred to Doncaster. It is seen on Askern Road in Bentley.
.... Thus prolonged infancy shapes human desires in two contradictory directions: on the one hand, on the subjective side, toward omnipotent indulgence in pleasure freed from the limitations of reality; on the other hand, on the objective side, toward powerless dependence on other people. The two tendencies come into conflict because the early experience of freedom and absorption in pleasure must succumb to the recognition of the reality-principle, in a capitulation enforced by parental authority under the threat of loss of parental love ...

The general term ice age or, more precisely, glacial age denotes a geological period of long-term reduction in the temperature of the Earth's surface and atmosphere, resulting in an expansion of continental ice sheets, polar ice sheets and alpine glaciers. There have been at least four major ice ages in the Earth's past. Outside these periods, the Earth seems to have been ice-free even in high latitudes. There is evidence that greenhouse gas levels fell at the start of ice ages and rose during the retreat of the ice sheets, but it is difficult to establish cause and effect. Greenhouse gas levels may also have been affected by other factors which have been proposed as causes of ice ages, such as the movement of continents and vulcanism. Although the last glacial period ended more than 8,000 years ago, its effects can still be felt today. For example, the moving ice carved out landscape in Canada, Greenland, northern Eurasia and Antarctica. The erratic boulders, till, drumlins, eskers, fjords, kettle lakes, moraines, cirques, horns, etc., are typical features left behind by the glaciers. The Dutch IJsselmeer lake is covered with icerocks hummocks, caused by the cold weather of the passed days. At some places even higher than 6 meter!
Photo taken of hummocks at the IJsselmeer (Markermeer) near Uitdam. On the background you can see the skyline of Almere. A hummock is a boss or rounded knoll of ice rising above the general level of an ice-field, Hummocky ice is caused by slow and unequal pressure in the main body of the packed ice, and by unequal structure and temperature at a later period. Blue ice occurs when snow falls on the ice. The blue color is actually created for the same reason that water is blue, that is, its slight absorption of red light due to an overtone of the infrared OH stretching mode of the water molecule.
Een ijstijd of glaciatie is een geologisch tijdvak waarin ijskappen voorkomen. In het Engels wordt dit een periode van ice-house genoemd, als tegenhanger van een ijskaploze periode, de greenhouse ("broeikas"). Aangezien er gletsjers liggen op bijvoorbeeld Groenland of Antarctica, leven we tegenwoordig in een ijstijd. Men neemt aan dat dit in de gehele geologische geschiedenis van de Aarde minstens vijfmaal het geval is geweest, waarvan eenmaal zelfs zo sterk dat de ijskappen van de polen vrijwel tot aan de evenaar waren opgerukt. Ook zijn er periodes dat er aanzienlijke opwarming optrad waarbij die ijskappen grotendeels waren weggesmolten. Het klimaat op Aarde wordt beïnvloed door vele factoren, zoals de intensiteit van de zonnestraling, de ligging van de continenten, de continentverplaatsingen, vulkanisme, de zeestromen, de bedekking van het land door vegetatie, het weerkaatsingsvermogen van het aardoppervlak en vele kleine andere factoren. Met behulp van klimaatmodellen wordt door wetenschappers een reconstructie van het klimaat en de klimaatveranderingen in het verleden gemaakt. Alhoewel er een zekere consensus bestaat onder wetenschappers, zijn er nog vele onzekerheden en tegenstrijdigheden in dit onderzoek.
Hierboven een foto van kruiend ijs. Zoetwatermeren kunnen spectaculair bevriezen. Grotere meren zoals het IJsselmeer (IJmeer) hierboven hebben bijna altijd wel golven, en dit werkt directe bevriezing van het wateroppervlak tegen. Eerst vormen zich kleine ijsschotsen, die naar de kust drijven onder invloed van de wind. Deze schotsen vormen zo een ijsveld op het water dat de golven dempt, en uiteindelijk vriezen alle schotsen aan elkaar vast tot een massa. Voordat dit gebeurt schuren de schotsen voortdurend langs elkaar heen en schrapen zo stukjes ijs van elkaar af; elke schots krijgt zo een witte rand. Zulk ijs is dus totaal niet geschikt om op te schaatsen. Wanneer grotere delen van het meer bevriezen beginnen de platen, die soms een paar vierkante kilometer groot zijn, langzaam tegen elkaar te bewegen onder invloed van de wind en stroming. Dit heeft kruiend ijs tot gevolg: de ijsschotsen worden met kracht gebroken en op elkaar gestapeld langs de dijken langs het meer. Dit hoeft niet alleen bij dun ijs te gebeuren; soms kruit het ijs bij een dikte van meer dan 20 cm. De stapels ijs worden dan hoog, en het geluid is oorverdovend. Deze foto is genomen bij Uitdam met Almere aan de overkant van het Markermeer.
Bridge # 150 on the Leeds Liverpool canal, near to Foulridge. 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.

The Full Moon of June 24, 2021, colloquially called the "Strawberry Moon," just rising over the distant hill at McGregor Lake in southern Alberta. The disk of the Moon is flattened by atmospheric refraction and tinted golden from atmospheric absorption, as is the case for all rising and setting Moons, and Suns.
This is an exposure blend of two images: a long one for the sky and water, and a shorter one for the disk of the Moon, to prevent it from being overexposed. This was with the Canon EOS Ra and 200mm L lens and 1.4x Extender for 280mm focal length.

Poem.
The mercury greys, the tree-lined ebony silhouettes, deep indigo and silver-coated marbling, gleaming, beaming off the cloud-reflected bay-
Dazzles and spell-binds.
That precious God-given ambience of early dawn blinds us but etches blurred images of heavenly proportions to our senses.
The mesmerising light, the near-silent water’s edge only broken by the lilting call of the oyster-catcher or the muffled comments of stirring sailors aboard their dreamy yachts.
These familiar sounds, the salt-laden odours of a near-calm bay and the silent, gentle absorption of the sun’s rays rouses and energises a myriad of life-forms to a glorious new day.
To witness this scene is pure bliss.
To hear, feel and sense it, is almost indescribable.

Name: Aileen Hammer
Allegiance: Villain
Powers:
* Can generate and absorb high amounts of energy and expel it through powerful energy beams from her eyes and hands.
* Enhanced strength, durability and stamina
* Flight
* Mild Healing factor
Weapons: None
Key Weakness: Excessive absorption of foreign energy drains her own life source and can result in her losing consciousness.
Origin:
Aileen was a sleeper agent for T.O.X.I.N. who infiltrated the "traitor" soldiers which fled the corporation and became heroes when the first ever Meta's were created. Her and her husband would go by the hero aliases, Powerhouse and E-Beam and fight alongside the first ever hero team which had members like Red Star and Gladiator. Only to later deceive them and kill those on the team after revealing their true intentions, but Red Star and Gladiator did not know of this and later disappear due to their own personal altercations. Aileen and her husband then retired as heroes after suffering the teams tragedy of being killed by a "mystery villain" then be ordered to create the ultimate weapon. Soon later they would conceive a child who they hoped would grow to become T.O.X.I.N.'s own weapon of mass destruction by having both super strength from the father and energy powers from the mother. When the child grew up believing the parents where heroes the child eventually became a hero too using their abilities going by a superhero name. Although when the parents revealed their true plans it did not bode well and the hero would be forced to battle their own parents, killing the father in the process. The mother would then hate her child from then on and become the all absence of hope, total despair and make it her duty to kill the hero.

Ramsau bei Berchtesgaden is famous for its high mountains, including the third highest mountain in Germany, the fabled Mount Watzmann - 2713 m, and for the lake Hintersee. The 16th-century Pfarrkirche St. Sebastian - Church of Ramsau is often on postcards. The church is the most photographed place along the Alpenstrasse. Josef Mohr, the man who penned the lyrics to Silent Night, preached here. Ramsau is situated in the heart of the Bavarian Alps in the Berchtesgaden National Park.The scenery between the Watzmann Mountain and valley of Lake Königssee are both enticing and overwhelming. Whether you are a walker or a cyclist, you will be able to relax and wind down while pursuing your choice of activity. In winter, tourists enjoy cross-country ski trails, sled runs, and ice skating on the Hintersee.
The Ramsau parish church St. Sebastian with the Reiteralpe mountains in the background is a much photographed scene and I confess I found its attraction quite magnetic. To make the foreground even more attractive as the background I did a little fun cooperation with my talented friend AnnA Theodora. The idea started when I saw her self portrait photo in front of curtains. A beautifully and elegantly composed photo. I edited some additional lights and made a perfect window scene for this image. It was time for Anna to close the curtains before the night falls. Best enjoyed in large on black. I hope the image comes alive. "Anna it's time to close the curtains in Ramsau!"
Midden in de Duitse Alpen ligt het geweldige Berchtesgaderland. Het is één van de meest geliefde binnenlandse vakantiebestemmingen van onze oosterburen en terecht! Het schitterende natuurgebied ligt 25 km. ten zuidwesten van Salzburg in een soort kom, gevormd door 1700 meter tot 2700 meter hoge bergtoppen. Eén van deze toppen, de Watzmann, is de op één na hoogste berg van Duitsland. Ongeveer 12 km. ten westen van Berchtesgaden bevindt zich in het Alpen- en Nationale Park Berchtesgaderland de gemeente Ramsau, aan de voet van de Watzmann 2307 m. en de Hochkalter 2608 m. met de Blaueis-gletsjer. Ramsau bei Berchtesgaden bevindt zich in een imposant hooggebergte en is omgeven door de Königsee en de Hintersee met zijn sprookjesachtige bos. Vanuit Ramsau kunt u direct beginnen aan een wandeling door de overweldigende natuur. Ramsau in Berchtesgaden bezit een opvallende kerk de St .Sebastiankirche die is al van ver te zien in een schilderachtige omgeving gelegen aan een bergriviertje. Deze kerk is één van de meest gefotografeerde kerken van Duitsland mede door de prachtige Reiteralpe berg als achtergrond. Om ook de voorgrond wat meer aantrekkelijk te maken is het idee ontstaan om samen te werken met talent volle fotografe AnnA Theodora. Haar laatste zelfportret foto past zo mooi in dit plaatje. Na enige bewerking en toevoegen van sfeerverlichting komt nu ook de voorgrond meer tot leven en zal het nieuwsgierigheid wekken van de kijker en hopelijk hiermee verrassen. Anna mag de gordijnen dicht doen in Ramsau. Het mooist in het groot op zwart. Vooral op gure winteravonden is het fijn om de donker buiten te sluiten en een warme ambiance te creëren door de gordijnen dicht te doen.
The waning last quarter Moon rises in conjunction with the Pleiades star cluster, here coming out of a band of clouds just above the northeast horizon, with the Moon just a degree or two above the horizon.
This was the evening of August 25, 2024. Earthshine is just visible on the "dark side of the Moon." And yes, the sky really was that colour, as this was so low with the field lit by moonlight reddened by atmospheric absorption.
Technical:
This is a blend of 8 exposures taken in quick succession, from 30 seconds for the stars and base sky, to as short as 1/8-second for the lunar disk, blended with Lights1 luminosity masks created with Lumenzia extension panel in Photoshop. The exposure blending results in an image that better resembles what the eye could see in the scene with such a high dynamic range in brightness.
The Canon R5 was at ISO 1600 and on the Astro-Tech 90CFT refractor telescope at f/4.8 for a focal length of 430mm. It was on the Astro-Physics Mach1 mount tracking the sky at the sidereal rate. Thus the blurred clouds. Finishing touch glows and Orton-style effects added with Luminar Neo and Nik Color EFX.
This is the cumulation of 154 Hubble orbits pointing at this cluster!
Looking at the largest elliptical galaxies, almost all of them are disturbed in some way, almost as if they have recently consumed or interacted with a smaller neighbor. The shells which align more or less neatly with the long axis are indicative of absorption of a much smaller galaxy, which seems to be the case for all of the interacting ellipticals. You can almost imagine if time were sped up that this cluster would be a roiling ball of activity with the largest galaxies consistently snacking on smaller morsels. Also visible are many lenticular galaxies, seemingly devoid of star formation but still maintaining some semblance of their past spiral selves.
What is interesting to me is the blue background galaxies. My best guess would be that they are starforming immensely and putting out a lot of ultraviolet light. All that light gets redshifted and shows up in the 435 filters.
Details!
I used WFC3 data for low infrared and ACS data for near-infrared/visible light.

WR-134 is a Wolf Rayet star located in Cygnus. The star itself, located about 6000 light years from Earth, is surrounded by a Oxygen-dominated nebula that is being blown around by radiation and winds from the WR star itself. The star itself is about 5 times the radius of our sun and was one of the first three stars observed in Cygnus to have intense emission lines rather than continuous or absorption lines. This class of stars is now known as Wolf-Rayet stars.
This image is a HOO Bicolor image totaling about 34.7 hours of exposure time taken over 7 nights.
This image will eventually be mosaic'd with the Crescent Nebula, which I am current halfway done gathering data for.

Astronomers have taken an inventory of the most deeply embedded ices in a cold molecular cloud to date. They used light from a background star, named NIR38, to illuminate the dark cloud called Chameleon I. Ices within the cloud absorbed certain wavelengths of infrared light, leaving spectral fingerprints called absorption lines. These lines indicate which substances are present within the molecular cloud.
These graphs show spectral data from three of the James Webb Space Telescope’s instruments. In addition to simple ices like water, the science team was able to identify frozen forms of a wide range of molecules, from carbon dioxide, ammonia, and methane, to the simplest complex organic molecule, methanol.
In addition to the identified molecules, the team found evidence for prebiotic molecules more complex than methanol (indicated in the lower-right panel). Although they didn't definitively attribute these signals to specific molecules, this proves for the first time that complex molecules form in the icy depths of molecular clouds before stars are born.
The upper panels and lower-left panel all show the background star’s brightness versus wavelength. A lower brightness indicates absorption by ices and other materials in the molecular cloud. The lower-right panel displays the optical depth, which is essentially a logarithmic measure of how much light from the background star gets absorbed by the ices in the cloud. It is used to highlight weaker spectral features of less abundant varieties of ice.

Snowshoe hares, with their unique dietary habits, are remarkable creatures. They thrive on a primarily herbivorous diet, enjoying abundant greens like grasses, ferns, and clover in warmer months to replenish energy reserves and prepare for winter.
As snow covers the ground, their diet shifts to twigs, tree bark, and spruce needles, relying on crucial sources like willow, alder, and birch shrubs. Their digestive systems are uniquely adapted to extract nutrients from this tough vegetation—an ability not found in all herbivores.
Furthermore, snowshoe hares' practice of coprophagy, re-ingesting their fecal pellets to maximize nutrient absorption, is a testament to their extraordinary adaptability. This survival strategy allows them to thrive on lower-calorie food, showcasing the remarkable adaptations of these incredible animals.

Another day, another kairos overflowing with self-expression, self-reflection and possibly a touch of self-absorption.

Family outing... Cowry snails usually inhabit rocky and coral areas where they browse on algae, or encrusting invertebrates like sponges and bryozoans (diet varies with species). They are most active at night and conceal themselves in crevices during the day. In cowries, the spire (pointed end) of the shell is overgrown by the last whorl, resulting in a rounded, domed shape. The shell-producing mantle tissue has two special folds that extend outside the shell in the cowries. These mantle folds keep the shell clean and polished, and prevent boring or encrusting organisms from causing damage to the shell surface. The mantle is covered with frilly, branched projections called papillae. The functions of the papillae are not clear: they may provide camouflage for the animal by breaking up the snail’s outline; or may allow absorption of oxygen from the seawater.

Firing the ever-impressive .50 BMG round from a rotary 5+1 magazine with chamber selector buttons, this bolt-action sniper rifle is best suited for a marksman that is often on the move.
The rifle's rugged construction, bipod and foregrip will help the marksman quickly take aim, further supported by the intelligent LIDAR-equipped scope that uses a long-range laser emitter to detect wind strength and direction as well as range to target. The scope then automatically calculates the bullet drop and wind interference with the round, and adjusts its crosshairs within the scope accordingly.
This system can also be switched off, as the scope is still manually adjustable through the D-Pad and the 2-slider, 3-button control system for precision finetuning as needed.
The muzzle brake helps mitigating recoil as well as redirecting the muzzle flash. The barrel (as well as the rest of the internals) has been cold hammer forged out of a titanium-vanadium alloy. This alloy is highly durable yet relatively light, and is also highly resistant to moisture.
The stock features a height-adjustable cheekrest, a semi-flexible buttpad for increased recoil absorption, a monopod that retracts inside the stock, and a few rubberized grip panels.

The Seestar S50 started this image at 10:00PM to 3:50 AM. During this time 976 ten-seconds subframes were taken. Of those 865 passed muster. The images were pieced together as a mosaic. Image right annotates some points of interest.
LdN refers to Lynds Catalog of Dark Nebulae. What is a dark nebula? (Wikipedia: A dark nebula or absorption nebula is a type of interstellar cloud, particularly molecular clouds, 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 in the coldest, densest parts of molecular clouds.)
Bonsai Nihon Chaenomeles maulei - Sakura - It belongs to the rosaceae family.
An attempt to obtain a light painting outside in natural noon light, without using any torches/reflectors nor long exposure, just positioning the subject at its best to receive the last sun rays in a portion of the compo and to obtain in the rest a fairly good light absorption.

The animal in the photograph is a Marine Iguana.
Common name: Marine iguana
Scientific name: Amblyrhynchus cristatus
Family: Iguanidae
Endemic range: Galápagos Islands
Conservation status: Vulnerable (IUCN)
Confidence: High (distinct morphology unique to this species).
Detailed Description
Overall Form
The marine iguana is the only lizard species in the world adapted to a marine lifestyle. Adults typically measure 60–140 cm (2–4.5 ft) including the tail.
Key characteristics visible in the image:
1. Body posture
The iguana is lying flattened against the warm ground with limbs extended outward.
This “sprawled basking posture” maximizes heat absorption after swimming in cold ocean water.
2. Head
Short, blunt snout specialized for scraping algae from rocks.
Heavy armored scales and bony ridges across the skull.
Small nostrils positioned high on the snout.
Marine iguanas possess salt glands near the nose that expel excess salt from seawater ingestion (often seen sneezing salt crystals).
3. Dorsal crest
A row of triangular spines runs from the neck down the back toward the tail.
These spines are larger in males and used partly for display.
4. Skin texture
Thick, rough, bead-like scales.
Coloration here appears dark charcoal/black with greenish tones on the limbs.
Dark coloration aids rapid solar heating after diving.
During breeding seasons some populations develop red, green, or turquoise highlights.
5. Limbs
Strong, widely splayed forelimbs with long curved claws.
Adapted for gripping volcanic rock in surf zones.
6. Tail
Long, laterally compressed tail functioning as a propulsive swimming paddle.
Behavior Shown in the Image
The iguana is thermoregulating.
Marine iguanas dive into cold waters (often 10–18°C / 50–64°F) to graze on algae. After feeding they must:
Exit the water.
Flatten the body against warm rock or sand.
Absorb solar heat to raise body temperature.
The posture in the photo — limbs spread, belly pressed flat — is typical post-foraging basking behavior.
Diet
Marine iguanas are primarily herbivorous marine grazers.
Main foods:
Red algae
Green algae
Occasionally intertidal seaweed
Large males can dive 10–20 meters (33–66 ft) and remain underwater for 20–30 minutes.
Ecological Significance
Marine iguanas are a classic example of adaptive radiation in the Galápagos.
They evolved from land iguanas that colonized the islands millions of years ago and adapted to a marine feeding niche.
Major predators include:
Galápagos Hawk
Feral cats and dogs (on some islands)
Key Visual Traits for Identification
Blunt algae-scraping snout
Dorsal spiny crest
Thick armored scales
Flattened swimming tail
Dark coloration for solar heat absorption
Occurrence only in the Galápagos
These traits together uniquely identify the species.
This was such a hot day that for most of the time, this small copper was keeping its wings folded and pointing at the sun to reduce energy absorption and avoid over-heating. Eventually I managed a couple of shots with wings capturing light from the sun.
For me to observe, homeostasis in action.
With other small butterflies, on sunny days, I've been able to persuade them (esp. common blue) to open their wings by gradually shading them at a distance, then removing the shade.
Thanks to everyone who views, faves or comments on my pictures.

EN_ Surely the best known nebula of the sky in the world, and of course if its beauty is unmatched.
The Orion Nebula is a stellar nursery where new stars are forming at more than 1500 light years, full of emission, reflection and absorption nebulas located on the edge of a gigantic complex of molecular clouds, these colorful nebulae only represent a small difference of the richness of interstellar material of this galactic neighborhood. Inside this well-studied stellar nursery, astronomers have also identified what appear to be numerous young planetary systems, M42 is one of the brightest nebulae in the sky visible on the sword of the Orion hunter as a diffuse and dim star.

Nebulosa de Orión
Seguramente la nebulosa mas conocida del cielo en el mundo, y como no si su belleza es inigualable.
La nebulosa de Orión es una guardería estelar donde están formando nuevas estrellas a más de 1500 años de luz, plagada de nebulosas de emisión, reflexión y absorción situadas al borde de un complejo gigantesco de nubes moleculares, estas vistosas nebulosas tan solo representa una pequeña diferencia de la riqueza de material interestelar de este barrio galáctico. En el interior de esta bien estudiada guardería estelar, los astrónomos también han identificado lo que parecen ser numerosos sistemas planetarios jóvenes, M42 es una de las nebulosas mas brillantes del cielo visible en la espada del cazador Orión como una estrella difusa y tenue.
The giant rock carving of King Decebalus is placed opposite an ancient memorial plaque, carved in the rock on the Serbian side of the river facing Romania. The plaque, known as the Tabula Traiana, records the completion of Trajan's military road along the Danube and thus commemorates the final defeat of Decebalus by Trajan in 105, and the absorption of the Dacian kingdom into the Roman Empire. But today Decebalus is resurrected and is once again confronting the Romans…

Some of you may have noticed that I've not been posting consistently recently. I can only blame it on the exam papers that I have to bring home to mark every night in order to meet the deadline. 180 scripts in 12 days, no pressure!
Every day I come across an answer so ridiculously brilliant, I wished I could award it marks for humour but I can't because there is a fine line between creativity and stupidity. So this whole week I'll be sharing some of these amazing responses in Lego form.

Metaphor question in comprehension passage: What does the author mean when he describes the selfie stick as a "lightning rod of narcissism"?
Student's answer: The author means that just as the "lightning rod" holds insurmountable power for the person wielding it, the selfie stick also possesses the powerful quality of self-absorption for the user.

The Full Moon at the equinox, on March 20, 2019, reaching full phase only fours hours after the moment of the vernal equinox, and here captured rising very shortly before the moment of the Full Moon. I shot this while the Moon was still rising and in a deep blue sky, and tinted yellow from atmospheric absorption. Even so, this is a blend of short (for the Moon) and long (for the sky) exposures to capture the dynamic range.
All with the 105mm Traveler apo refractor and Canon 60Da camera at ISO 100.
