It rained for about a week straight across the Midwest in August 1990, but on the 24th the sun peeked out in Chicagoland long enough to illuminate Soo Line SD60 duo 6005-6016 running on the Indiana Harbor Belt at LaGrange IL with merchandise freight from Bensenville yard. The minimalist but classic Chinese Red and white paint scheme would soon start to disappear under Canadian Pacific's absorption of the old Soo.
It was such a beautiful day today I thought I'd take a hike; however, I decided to post a picture of a hike instead.
The Grand Prismatic Spring is 370 feet in diameter and the largest of the hot springs in Yellowstone. The center is an intense azure blue. Created by the unique bacteria and algae that live within each hued band of mineral-rich water, the reds, oranges, yellows, greens surround a deep blue core that is too hot to sustain life. The deep blue color of the water in the center of the pool results from the intrinsic blue color of water, itself the result of water’s selective absorption of red wavelengths of visible light. Though this effect is responsible for making all large bodies of water blue, it is particularly intense in Grand Prismatic Spring because of the high purity and depth of the water in the middle of the spring.

The comet was drifting fast toward east in Libra.
It was low in the west at the date, and stars showed obvious spectral spread due to atmospheric dispersion. Blue and green went higher, and red went lower. Blue got weaker due to atmospheric differential light absorption, and bluish ion tail got far fainter than expected. North is up, and east is to the left.

Csikszentmihalyi (1991) describes engaged reading as a state of total absorption and completely focused motivation. It is a single-minded immersion and represents perhaps the ultimate in harnessing the emotions in the service of performing and learning.

For this Picture of the Week, the NASA/ESA Hubble Space Telescope turned its powerful eye towards an emission line galaxy called NGC 3749.
When astronomers explore the contents and constituent parts of a galaxy somewhere in the Universe, they use various techniques and tools. One of these is to spread out the incoming light from that galaxy into a spectrum and explore its properties. This is done in much the same way as a glass prism spreads white light into its constituent wavelengths to create a rainbow. By hunting for specific signs of emission from various elements within a galaxy’s spectrum of light — so-called emission lines — or, conversely, the signs of absorption from other elements — so-called absorption lines — astronomers can start to deduce what might be happening within.
If a galaxy’s spectrum shows many absorption lines and few emission lines, this suggests that its star-forming material has been depleted and that its stars are mainly old, while the opposite suggests it might be bursting with star formation and energetic stellar newborns. This technique known as spectroscopy, can tell us about a galaxy’s type and composition, the density and temperature of any emitting gas, the star formation rate, or how massive the galaxy’s central black hole might be.
While not all galaxies display strong emission lines, NGC 3749 does! It lies over 135 million light-years away, and is moderately luminous. The galaxy has been used a “control” in studies of especially active and luminous galaxies — those with centres known as active galactic nuclei, which emit copious amounts of intense radiation. In comparison to these active cousins, NGC 3749 is classified as inactive, and has no known signs of nuclear activity.

Bridge #150, Leeds-Liverpool Canal, between Foulridge and Salterforth ('Hatter's Bridge' - 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 Badlands are an exposed section of the Queenston Formation, which was formed between 420 and 415 million years ago during the Middle and Late Ordovician periods.[8] During this period, the collision of Gondwana into Laurentia resulted in the formation of the Taconic Mountains.[9][10] The creation of these mountains also resulted in several basins, such as the Appalachian Basin and the Michigan Basin, in the interior of Laurentia.[8] Over time, the erosion of these mountains resulted in the formation of the Queenston Delta,[11] which drained into the Michigan Basin.[8] The deposition of mud eroded from the mountains during the Middle and Late Ordovician period formed the Queenston Shale.[9] The continuous deposition of the mud and sand from the mountains extended the Queenston Delta further into the Michigan Basin; however, as the mountains continued to erode, less and less mud and sand reached the delta, resulting in the formation of inter-layered beds of sandstone, shale and limestone throughout the Silurian period.[8] These inter-layered beds that overlay the Queenston Shale include Lower Silurian sandstones, such as the Whirlpool Formation, and dolostones, such as the Manitoulin Formation, which can be seen along the Niagara Escarpment.[12] The Queenston Shale overlies the shales and the inter-bedded limestones of the Georgian Bay Formation.[12] At the badlands site, glacial erosion of the overlaying sandstones and dolostones has caused the Queenston Formation to be the first layer of rock to underlie the soil.[8]
Queenston Formation[edit]
The Queenston Formation is characterized by its brick-red to maroon shales which are interlaced with smaller amounts of green shale, sandstone, and limestone.[9][12] The darker red shale is the result of introduction of the terrestrial muddy deposits into the Queenston Delta.[9][1] The shale beds are thin and fractured, with a structural dip westward towards the centre of the Michigan Basin.[9] Shales in the Queenston Formation are considered to have high density, low cation exchange capacities, and low water content.[13][1] The lighter red shale, which sits on top of the darker shale, is highly bioturbated and is composed of a combination of bioclasts and the reworked pieces of the darker shale below.[1] The distinct red, due to iron-oxide, colouring of these rocks is broken up with green-grey bands. The green-grey bands are thought to be caused by a change in the oxidation rate due to circulating groundwater[1] or bleaching by acidic groundwater.[11]
The lithology of the lighter and darker red shales at the Cheltenham Badlands site is categorized as smectite-poor, due to the clay content, ranging from 58% to 68% clay, and the dominant clay minerals, illite and chlorite.[1][11] The non-swelling illite in the shales can cause high pressures with repeated wetting and drying, resulting in failure of the shale structures.[1] The difference in the water absorption between illite and chlorite clay minerals can cause differences in swelling which results in larger shards of the shales breaking into smaller shards.[1] Once the shards are reduced to tiny and flaky shards, they become compacted and smooth; however, surface cracks during drying periods can lead to further erosion.[1]
NGC2170, known as the Angel Nebula is a reflection nebula in the constellation of Monoceros. The nebula formed about 6 million years ago and lies at a distance of 2700 light-years. It was discovered on October 16, 1784 by William Herschel.
In this image are bluish reflection nebula, a red emission nebula and many dark absorption nebula.

The NASA/ESA Hubble Space Telescope has made its stunning yearly observations of the Solar System’s giant planets, to reveal atmospheric changes.
The NASA/ESA Hubble Space Telescope has completed its annual grand tour of the outer Solar System. This is the realm of the giant planets — Jupiter, Saturn, Uranus, and Neptune — extending as far as 30 times the distance between Earth and the Sun. Unlike the rocky terrestrial planets like Earth and Mars that huddle close to the Sun’s warmth, these far-flung worlds are mostly composed of chilly gaseous soups of hydrogen, helium, ammonia, and methane around a packed, intensely hot, compact core.
Though robotic spacecraft have sent back snapshots of their visits to these four monster planets over the past 50 years, their swirling, colourful atmospheres are constantly changing. Fulfilling the role of a weather forecaster, every time Hubble’s sharp cameras revisit these worlds there are new surprises, offering fresh insights into their wild weather, driven by still largely unknown dynamics taking place under the cloudtops.
Hubble’s snapshots of the outer planets reveal both extreme and subtle changes rapidly taking place in these distant worlds. Hubble’s sharp view gleans insights into the fascinating, dynamic weather patterns and seasons on these gas giants and allows astronomers to investigate the very similar — and very different — variables that contribute to their changing atmospheres.
Jupiter
This year’s Hubble observations of Jupiter track the ever-changing landscape of its turbulent atmosphere, where several new storms are making their mark and the planet’s equator has changed colour yet again.
Hubble’s 4 September photo puts the giant planet’s tumultuous atmosphere on full display. The planet’s equatorial zone is now a deep orange hue, which researchers are calling unusual. While the equator has departed from its traditional white or beige appearance for a few years now, scientists were surprised to find a deeper orange in Hubble’s recent imaging, when they were expecting the zone to cloud up again.
Just above the equator, researchers note the appearance of several new storms, nicknamed “barges.” These elongated, deeply structured red cells can be defined as cyclonic vortices, which vary in appearance. Whilst some of the storms are sharply defined and clear, others are fuzzy and hazy. This difference in appearance is caused by the physical properties within the clouds of the vortices.
Researchers also note that a feature dubbed “Red Spot Jr.” (Oval BA), below the Great Red Spot where Hubble just discovered winds are speeding up, is still a darker beige colour, and is joined by several additional white, cyclonic storms to the south.
Hubble’s crisp views of Jupiter in 2020 was one of the most popular ESA/Hubble photo releases to date.
Saturn
Hubble’s new look at Saturn on 7 September 2021 shows rapid and extreme colour changes in the bands in the planet’s northern hemisphere, where it is now early autumn. The bands have varied throughout Hubble observations in both 2019 and 2020. Hubble’s Saturn image catches the planet following the southern hemisphere’s winter, evident in the lingering blue-ish hue of the south pole.
Uranus
Hubble’s 25 October view of Uranus puts the planet’s bright northern polar hood in the spotlight. It’s springtime in the northern hemisphere and the increase in ultraviolet radiation from the Sun seems to be causing the polar region to brighten. Researchers aren’t sure why. It could be a change in the opacity of atmospheric methane haze, or some variation in the aerosol particles. Curiously, even as the atmospheric hood gets brighter, the sharp southernmost boundary remains at the same latitude. This has been constant over the past several years of Hubble observations of the planet. Perhaps some sort of jetstream is setting up a barrier at that latitude of 43 degrees.
Neptune
In observations taken on 7 September 2021, researchers found that Neptune’s dark spot, which was recently found to have reversed course from moving towards the equator, is still visible in this image, along with a darkened northern hemisphere. There is also a notable dark, elongated circle encompassing Neptune’s south pole. The blue colour of both Neptune and Uranus is a result of the absorption of red light by the planets’ methane-rich atmospheres.
Notes
These new Hubble images form part of yearly maps of the entire planet taken under the Outer Planets Atmospheres Legacy programme, or OPAL. The programme provides yearly Hubble global views of the outer planets to look for changes in their storms, winds, and clouds.
Note: The planets are not shown to scale in this image.

A zoomed-out look at the S.P.I.D.E.R. Drone on the Lunar landscape :) Last pic for now. Features video on YouTube: youtu.be/Q3HC0IzGPfc
Work-in-progress shots, and more on my Instagram @LEGO_stud as well. Full description below <3 :
----------------------------------------------------------------------------------------------
The Solar-Powered Interstellar Drone for Extraterrestrial Research (S.P.I.D.E.R.) is finally completed at the 'Moonbase Celebration 50'.
With onboard intelligence, a formidable assortment of tools, and unlimited renewable power, this endlessly useful companion is sometimes referred to as 'GRAMPS' - Giant Robotic Assistant & Mobile Power Station (especially by arachnophobic astronauts).
Future missions will be accompanied by these units, to aid in planetoid habitability investigation and geo/bio research. Manipulator arms, coupled with highly advanced sensors allow this drone to examine samples, move debris, haul equipment, and even carry out rescue operations for astronauts in danger.
Fully capable of traversing uneven terrain, and repelling into crevaces with it's winch, this robotic research assistant can go just about anywhere on atmospheric and non-atmospheric terrestrial landscapes.
Prepare to give Space exploration a leg-up (or six!) and take your celestial crew to a whole new level of awesome adventure with a giant (robot) S.P.I.D.E.R. on board!
------ [[[¤]]] ------
This MOC has been a journey, developing a seamless transition through System and CCBS/Bionicle elements. With adjustable Greebles to simulate actuators. Fully articulated through each leg, the model is stable, poseable, and quite dynamic.
The features include: adjustable solar arrays, whiskers, and rear hitches, poseable manipulator arms (3), legs with up to 12+ points of articulation each + working shock absorption, opening hatch to reveal central core, storage for a large assortment of space tools, and a working winch (which can support the full weight of the build).
Thanks for checking it out, I hope you enjoy it!

10 November 2020: Update on The Corona Pandemic – The corona restrictions are beginning to pay off, with the number of hospitalisations dropping and the number of new infections going down strongly. Last week, 597 patients had to be taken to hospital each day on average, coming from 656 the week before. Yesterday's figure came in at 400, while 294 patients were allowed to return home again. The best news we’ve heard in a long time came from Pfizer announcing yesterday that an early analysis of its coronavirus vaccine trial suggested the vaccine was robustly effective in preventing Covid-19. A first analysis of the data found that the vaccine that they developed together with the German pharma company BioNTech was more than 90 percent effective in preventing the disease among trial volunteers. If the results hold up, that level of protection would put it on par with highly effective childhood vaccines for diseases such as measles. Other interesting reading was the outcome of a study of 186 coronavirus patients at a Belgian hospital revealing that a lack of sufficient vitamin D on admission can be linked to increased risk of severity and death from a Covid-19 infection. I knew that Vitamin D stimulates the absorption of calcium and magnesium but did not know that it strengthens and regulates the immune system. Fully loaded with vitamins and supplements I continue my search for eye-catching scenes in my hometown. On display today is the old post office on the Korenmarkt – Korenmarkt, Ghent, Belgium.

Messier 52 (also known as M 52 or 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.[1]
NGC 7635, also called the Bubble Nebula, Sharpless 162, or Caldwell 11, is a H II region[1] emission nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot, 8.7[1] magnitude young central star, the 15 ± 5 M☉[4] SAO 20575 (BD+60 2522).[7] The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow.[7] It was discovered in 1787 by William Herschel.[5] The star SAO 20575 or BD+602522 is thought to have a mass of 10-40 Solar masses.

Gyulbudaghian's Nebula(in left- bottom corner) is a little-known variable reflection nebula, similar to Hubble's variable nebula.
t the heart of the Herbig-Haro object lies the variable Herbig AbBe pre-main sequence star PV Cep. This is a newly formed star that is surrounded by a rotating disk of material. At right angles to this disk are two jets of material, streaming away from the star at high speeds. We see the effects of one of these jets on the north side of PV Cep as the stream of material meets the surrounding gas in the interstellar medium. The jet to the south is obscured by a dark nebula (producing an absorption of over 3 magnitudes) (text: www.skyhound.com/observing/archives/oct/GM_1-29.html )

Rover is a British automotive brand that was used for over a century, from 1904 to 2005. It was launched as a bicycle maker called Rover Company in 1878, before starting to manufacture autocars in 1904. The brand used the Viking longship as its logo. The rights to the brand are currently part of Jaguar Land Rover, which continues to produce Land Rovers, but no Rover automobiles are currently in production and the brand is considered dormant.
Despite a state-controlled absorption by the Leyland Motor Corporation (LMC) in 1967 and subsequent mergers, nationalisation, and demergers, the Rover brand retained its identity, first as an independent subsidiary division of LMC, and subsequently through various groups within British Leyland (BL) through the 1970s and into the 1980s.
The Rover brand then became the flagship brand of the newly and eponymously renamed Rover Group in 1988, which included the actually stronger and more valuable brand names Land Rover and Mini as it passed first through the hands of British Aerospace and then into the ownership of BMW Group. Sharing technology with Honda and financial investment during the BMW ownership led to a revival of the brand during the 1990s in its core midsize car segment.[3]
In 2000, BMW sold Rover and related MG car activities of the Rover Group to the Phoenix Consortium, who established the MG Rover Group at Longbridge. BMW retained ownership of the Rover brand, allowing MG Rover to use it under licence. In April 2005, Rover-branded cars ceased to be produced when the MG Rover Group became insolvent. The MG Rover Group's assets then got split up between two Chinese automakers – some were bought by SAIC Motor, who obtained technology that was incorporated into a new Chinese line of Roewe branded luxury saloons. Other assets were bought by Nanjing Automobile.
BMW sold the rights to the Rover brand to Ford in 2006 for approximately £6 million, the latter exercising an option of first refusal to buy it dating back to its purchase of Land Rover in 2000. Ford thus reunited the original Rover Company brands, primarily for brand-protection reasons.[4] In March 2008, Ford reached agreement with Tata Motors of India to include the Rover brand as part of the sale of their Jaguar Land Rover operations to them. Legally the Rover brand is the property of Land Rover under the terms of Ford's purchase of the name in 2006. Wikipedia
The rising Full Moon of February 27, 2021, the "Snow Moon" of the year. The Moon was technically fullest earlier in the day, some 16 hours before I shot this, and so was slightly past full when it rose for me this evening in southern Alberta.
This is a composite stack of 9 short exposures for the Moon, blended with a single longer exposure for the ground and sky taken at the start of the moonrise sequence. But using the same exposure for the moons as I used for the sky would have resulted in vastly overexposed moons. As it was, I adjusted the exposures for the Moon from 0.6 seconds for the first (lowest) Moon to 1/30 second for the last (highest) Moon, to keep the moons properly exposed through the sequence, as it brightened as it rose. But it remained very yellow throughout due to atmospheric absorption of the blue wavelengths.
The background exposure for the ground and sky was 2.5 seconds. The sky was much darker than the Moon, because it rose nearly 45 minutes after sunset this night, so the sky had darkened quite a bit by moonrise.
All shots were through a SharpStar 76mm EDPH apo refractor with the matching SharpStar 0.8x field flattener/reducer, for an effective focal length of 335mm at f/4.4. The camera was the Canon EOS Ra at ISO 100.
I shot images every 5 seconds, for possible use in a time-lapse. But having images spaced that closely together in time made it possible to select images with the Moon's disk just nicely separated to be touching. While the Moon moves its own diameter every 2 minutes due to Earth's rotation, the effect of atmospheric refraction will make it appear to rise at a different rate when it is closer to the horizon than when it is higher. Having lots of frames to pick from made it possible to pick just the right ones for the correct spacing. As it was, the time between the frames used for this composite was about 2 minutes.

This past July I was fortunate enough to spend 11 days trekking the Huayhuash Circuit in Peru. For years visiting the Huayhuash had occupied a spot near the top of of things to experience at least once in my lifetime. The journey produced far too many stories to share in a short post like this so I’m (slowly) putting together a blog post. I have released ten new images from the Huayhuash trek on my website (www.michaelbollino.com/new-releases/) for those who care to see a sneak peak.
This particular image is from the second to last day of the trek and marks a particularly memorable moment. The day’s route climbed to a 16,000 foot pass and then remained high as it meandered along a long ridge. The ridge was continually swept by high winds which pushed and pulled the swirling clouds seen here over Jirishanca. By this point Jirishanca had easily become my favorite mountain in the Huayhuash but I had yet to capture it properly. Three condors soon appeared overhead, taking turns soaring between myself and the summit of Jirishanca then back again. I found cover from the wind behind a large boulder and began shooting. I sat there for a long while taking everything in. The scene felt massive. As a person with a deep connection to the natural world, and as a photographer who enjoys recording and interpreting this connection, moments like these leave impressions which remain long after the event itself ends. This sort of pure experience has always been my primary answer to the question of “why” I go into nature and, subsequently, why I photograph the natural world. During these moments thoughts and words drop away, become meaningless (perhaps burdensome), and act only to cloud the mind and detract from the experience. Look, listen, absorb, react, shoot. These moments may last for a few minutes or much longer, as it did on this day. Then, in an instant, the spell is broken, the absorption ends, and the only thing left to do is to move on your way, grateful for the experience. To me this is what exploring nature is all about.

- This is a Light Painting by Candlelight -
I handheld a candle in total darkness to paint these amazing huge callas with the light of its flame.
I conceived this technique as a new discipline in the LP, inspired at the Masters of Antiquity because I don't like to use electric nor electronic lighting. In this shot, I started panting from the bottom line, high-lighting the stems up to the flowers during a long exposure. Here, most of the efforts have been profused in doing my best to equally distribute the candle light, avoiding my own hands, arms and camera shadows, yet obtaining the wished Chiaroscuro with maximal attention to not 'burn' with excessive close light every flower, obtaining a fairly good light absorption.
The stems lead upwards until the corollas (or chalices) to celebrate their beauty & bountifulness.
Every calla looks to me like a ballerina wrapped in veils but each one has a different shape, hence the title.

The plant finds application in various spheres of life. Moss has long been most valued as a heater. Advantages of haircap: resistance to rot, heat preservation, moisture absorption in rainy periods, ensuring air exchange, thanks to the bactericidal qualities of the logs do not rot. For the insulation of houses, fresh plants are used, which are placed between wooden elements during construction. It is recommended to pre-clean the moss from extraneous sticks, twigs, cones, grass.
Peculiar rigid threads are obtained from the stems when the leaves are removed. After certain manipulations (soaking and combing), the stems can be used as threads for weaving mats, rugs, dense curtains, baskets. Rigid threads are also used for making brooms, brushes.
Official medicine does not use this plant culture. However, in folk medicine and cosmetology, haircap has found a worthy application. For the preparation of decoctions, infusions, almost all parts of moss are used – stems, leaves, seeds. For medicinal purposes, it is recommended to harvest raw materials in late summer and early autumn, when the spore seeds ripen. In order to dry the plant qualitatively, it is laid out in the shade, in a well-ventilated room.
For this image, the NASA/ESA Hubble Space Telescope turned its powerful eye toward an emission-line galaxy called NGC 3749.

Taken in Les Halles, a large "shopping center" in the center of Paris. The wall is actually a work by Nathalie Junod-Ponsard called "Trajectoires absorbées" which means "absorbed trajectories" (not sure if the title relates to the absorption of light, or the fact that people in that gallery walk "absorbed in their thoughts" -the frenh expression "absorbées dans leurs pensées" ?)

The incredible vibrance of many Birds-of-paradise is in part due to the deep black feathers which make their more colorful plumage simply ‘pop’. A recent study looking closely at these black feathers found that they had a unique nanostructure that is super-efficient in light absorption. This results in one of the darkest blacks found in nature, rivaling those of highly specialized synthetic materials.

In observations taken on 7 September 2021, researchers found that Neptune’s dark spot, which recently was found to have reversed course from moving toward the equator, is still visible in this image, along with a darkened northern hemisphere. There is also a notable dark, elongated circle encompassing Neptune’s south pole. The blue colour of both Neptune and Uranus is a result of the absorption of red light by the planets’ methane-rich atmospheres.

High wheel bicycle and modern times; Krakow Old Town District, Poland;
The penny-farthing, also known as a high wheel, high wheeler or ordinary, is an early type of bicycle.
It was popular in the 1870s and 1880s, with its large front wheel providing high speeds, owing to it travelling a large distance for every rotation of the legs, and comfort, because the large wheel provided greater shock absorption.

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. 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 aan de rand van het Markermeer.

Alias: Kinesis
Name: Carlos Reyes
Gender: Male
Allegiance: Villain
Powers: Kinetic Energy Absorption and Control, along with Super Speed
Backstory: Carlos is a friend of the original Kinesis, Colton Brighton. He would find out about his powers a few years after Colton did. Carlos would move from Cardinal City, to Sunrise City, hoping to enrol into Somerset Academy. His application into the heroics program was accepted, and he would begin training to eventually become a hero. He adapted the name Kinesis from Colton, as he wasn't currently using it. After years of training, he was told that he wouldn't be a good hero, because of his aggressive tendencies. This would break him mentally, where he would lose all inspiration in becoming a hero. This led him down a dark path, and he eventually became a villain, who would try and sway heroes who were more violent in nature. It was at this time that Colton came back to being a villain, after he was fired from being a pizza delivery driver. They decided to share the name Kinesis. Now Carlos works as a mercenary in Sunrise City, occasionally doing jobs for the Sons of Silver.
This was more like what I wanted to see, and there can't have been many of these left by 1985. 3330 was the first of what would turn out to be the final batch of vehicles delivered to Wigan Corporation, before their absorption into GMPTE in 1974.
Although the combination of AN68 Atlantean and Northern Counties body was GMT's first choice, these were a bit different from the others ! They were GMT's oldest AN68s, having 'K' plates, they were GMT's only long AN68/2R chassis, and they were the only dual-door AN68s, with all the dual-door bodies ordered by GMT being on Fleetline chassis.
And there is also the small matter that this was the first production AN68 Atlantean, with chassis number 7200388. In fact, this batch (NEK 1-10K) took up 10 of the first 11 AN68s off the production line, with just one pesky Merseyside PTE one in the middle ! Shame it didn't get preserved ....

Positron emission tomography (PET) is a functional imaging technique that uses radioactive substances known as radiotracers to visualize and measure changes in metabolic processes, and in other physiological activities including blood flow, regional chemical composition, and absorption.
PET scanners can incorporate a CT scanner and are known as PET-CT scanners. PET scan images can be reconstructed using a CT scan performed using one scanner during the same session.
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.
Photographed in situ.
A common sight here in Australia, enjoying the similar climate to its native range of South Africa.
I wanted to grow this plant, especially to observe the development of these large, dynamic, eye-catching flowers.
But I learned over the years from gardening articles, seeing them in parks and friends who have them in their gardens - that they grow fast and are a nightmare to remove.
So, I have this one plant in a very large pot. A couple of years ago, I re-potted and was intrigued to see the roots. They are large, thick and tuberous looking - adapted for water absorption and storage.
The flowers emerge one at a time from the spathe, consist of three orange sepals and three purplish-blue or white petals. Two of the petals are joined together to form an arrow-like nectary. When the sunbirds sit to drink the nectar, the third petal opens to release the anther and cover their feet in pollen.
One tough, resilient and stunning plant.
The common name 'bird of paradise' is due to the resemblance of the open inflorescence to the display plumage and pose of certain species of bird-of-paradise. (The beak being downward, with wings open above and tail behind, as if in flight and reaching down in to a flower for nectar).
Strelitzia reginae, growing to 2 m or more in height. Leathery leaves up to 80 cm in length and 30 cm wide.

ok, enough self-absorption! back to the wild wild sea... on the northern CA coast, near Mattole Beach...
Die scheinbare Blüte ist ein Blütenstand, nur eine Scheinblüte (Pseudanthium). Die Schaufunktion entsteht durch die dicht weißfilzigen Hochblätter. Die eigentlichen Blüten sitzen zu vielen Hunderten, in einzelne Blütenkörbe organisiert, inmitten des Sterns beisammen und bilden zusammen mit den Hochblättern eine bestäubungsbiologische Einheit (Superpseudanthium).
Der blendend weiße Schimmer auf den Hochblättern entsteht dadurch, dass tausende kleine Luftbläschen an dem vielfach durcheinander gewirkten, krausen Haar das einfallende Licht reflektieren. Dies dient als Signal für nektarsuchende Insekten, als Verdunstungsschutz und als Schutz vor Wärmeverlust. Die Arbeitsgruppe um den belgischen Physiker Jean-Pol Vigneron der Universität Notre-Dame de la Paix in Namur hat herausgefunden, dass die Haare selbst aus parallelen Fasern mit 0,18 Mikrometern Durchmesser bestehen, was in der Größenordnung der Wellenlänge der UV-Strahlung liegt und zu deren Absorption führt. Das übrige Licht wird jedoch hindurchgelassen, sodass die Pflanze Photosynthese betreiben kann.
Bestäuber sind vor allem Fliegen sowie Hautflügler, Falter und Käfer. Die Scheinblüte bleibt bis in den Winter hinein erhalten.
Das Alpen-Edelweiß gilt in Österreich und Deutschland als stark gefährdet. Ursachen sind heute v. a. das Betreten und Befahren der verbliebenen Standorte, früher vor allem das teils gewerbsmäßige Pflücken. Auch in Österreich und der Schweiz steht das Alpen-Edelweiß in sämtlichen Bundesländern bzw. Kantonen unter strengem Naturschutz und darf nicht gepflückt werden. In Österreich wurde das Edelweiß bereits 1886 unter Naturschutz gestellt. Durch das Aufkommen des Tourismus in den Alpen war es rasch zu einem begehrten und haltbaren Souvenir geworden. Als ein Beispiel für gelungenen Schutz eines Vorkommens kann der Bestand an der Höfats in den Allgäuer Alpen aufgeführt werden. Dort wurden die vor allem in der Inflationszeit durch übermäßiges Pflücken stark zurückgehenden Restvorkommen des dort vorkommenden, bereits damals geschützten Alpen-Edelweiß durch die Allgäuer Bergwacht von 1935 bis 2007 zur Blütezeit bewacht. Hierzu hatte sie eigens ein Zelt und später eine Biwakschachtel errichtet. Heute haben sich dort die Bestände erholt und das Naturschutzbewusstsein der Berggänger ist größer geworden, sodass die Bewachung nicht mehr erforderlich ist. (Wikipedia)
Rover is a British automotive brand that was used for over a century, from 1904 to 2005. It was launched as a bicycle maker called Rover Company in 1878, before starting to manufacture autocars in 1904. The brand used the Viking longship as its logo. The rights to the brand are currently part of Jaguar Land Rover, which continues to produce Land Rovers, but no Rover automobiles are currently in production and the brand is considered dormant.
Despite a state-controlled absorption by the Leyland Motor Corporation (LMC) in 1967 and subsequent mergers, nationalisation, and demergers, the Rover brand retained its identity, first as an independent subsidiary division of LMC, and subsequently through various groups within British Leyland (BL) through the 1970s and into the 1980s.
The Rover brand then became the flagship brand of the newly and eponymously renamed Rover Group in 1988, which included the actually stronger and more valuable brand names Land Rover and Mini as it passed first through the hands of British Aerospace and then into the ownership of BMW Group. Sharing technology with Honda and financial investment during the BMW ownership led to a revival of the brand during the 1990s in its core midsize car segment.[3]
In 2000, BMW sold Rover and related MG car activities of the Rover Group to the Phoenix Consortium, who established the MG Rover Group at Longbridge. BMW retained ownership of the Rover brand, allowing MG Rover to use it under licence. In April 2005, Rover-branded cars ceased to be produced when the MG Rover Group became insolvent. The MG Rover Group's assets then got split up between two Chinese automakers – some were bought by SAIC Motor, who obtained technology that was incorporated into a new Chinese line of Roewe branded luxury saloons. Other assets were bought by Nanjing Automobile.
BMW sold the rights to the Rover brand to Ford in 2006 for approximately £6 million, the latter exercising an option of first refusal to buy it dating back to its purchase of Land Rover in 2000. Ford thus reunited the original Rover Company brands, primarily for brand-protection reasons.[4] In March 2008, Ford reached agreement with Tata Motors of India to include the Rover brand as part of the sale of their Jaguar Land Rover operations to them. Legally the Rover brand is the property of Land Rover under the terms of Ford's purchase of the name in 2006. Wikipedia
