The Pootatuck River flows through Sandy Hook, Connecticut with this pleasant walk behind the old Warner Store and neighboring businesses. This was undeveloped when I lived in the area over six decades ago. The river is named for a native American tribe that lived here in the colonial era. They disappeared due to disease, warfare, and absorption into other tribes.

Once again, I was the one idiot on the beach tonight. Let's talk about about the weather. LA is a weird place when it comes to inclement weather both in terms of how it's viewed by people and how weather services describe it. It's hard to avoid hearing about the drought in one way or another on a daily basis, and I found even I would do an old man snicker when I'd see an apartment building with sprinklers working at 2am on a wednesday, almost like they were trying to be sneaky in an attempt to have slightly less dead greenery than neighboring buildings. Don't they know California has negative water? It's always about the drought...until it begins to rain.Then it's panic. Granted, rain here is slightly more dramatic than other places i've lived in the sense that it's usually pretty heavy, accompanied by higher winds and it doesn't take long for the dry land to reject absorption and flood streets and storm drains. I for one, am all for some rain to rinse off some of the filth. Scotch has had 4 different bacterial infections in LA (which is 4 more than he had in the first 11+ years of his life on the East Coast) and I can't help but think it's from all the dirt, waste and trash that cover the grass and pavement in and around Hollywood. Without rain, it just accumulates. That's my working theory on how he's getting those infections. He doesn't eat at Chipotle so what else can it be?
This past week was mostly cloudy with some rain mixed in and it's been a 50/50 chance it seems on whether I will see a nice sunset or not. It could be great or it could stay gray and never get any other color until dark falls. I missed a few really amazing cloudy crimson sunsets--twice returning from the vet--and wished I knew of some places around Hollywood with interesting views facing West. I generally give myself a minumum of 1 hour before sunset to be in the car with a destination set or I skip it since that's about how long it would take during normal traffic to get to Venice or Malibu. I'd rather not drive an hour to see a sunset out of car window with no where to stop. Anyway, even with rain in Hollywood, it cleared a bit in the early afternoon and when I checked the weather channel app on my phone, saw that rain was expected here at 3pm with a 60-90% chance of rain through the evening. When I checked Venice however, it showed some rain at 3 but also only a 5-10% chance of rain between 4-6pm. I figured I'd take the chance and got in the car in the drizzle a little after 3 and began the drive to Venice. Venice Pier sits at the end of Washington Blvd and once I turn onto that road, I'm about 15 minutes away with the destination in sight. It heads straight towards the ocean and this is generally about when I know for sure what I can expect for the evening. Sure enough, I veer onto this 4 mile stretch and see gray with a bit of blue and yellow light above and immediately know I will not be getting the big, colorful sunset I was cautiously optimistic about.
Still, I was counting on that 5-10% the "up to the minute" weather report had offered earlier and since it was dry when I arrived, off I went in the wind for the beach. It's about a 4 minute walk from where I park to where I shoot and I only saw a handful of people wandering around, wearing raincoats and furry Ugg boots on the damp sand and wet boardwalk pavement. Clearly only the survivalists brave enough to tackle this weather were out. I got to the shore, lowered the tripod a few inches off the ground and stepped back in case some audacious water tried to get me when I wasn't looking. It was windy, the surf mostly choppy and it was difficult to focus. With the tripod as low to the ground as it can go, I was hoping to at least get some interesting streaks of water in the foreground as close to the camera as possible. The color wasn't really there but it wasn't all that bad and the clouds in front of me got more and more dramatic as sundown approached. I hadn't been there all that long before the wind picked up more and a few raindrops fell and it wasn't long after that when it began to pour. In the span of about 3 minutes, I went from dry to trying to keep my windproof umbrella from going inside out while I covered my camera and ran to the car. I'm no meteorologist--and no offense to any weather people here on Flickr--but I do have functioning eyeballs and despite what I saw before leaving, during the drive and once I arrived, I still trusted that weather report. This storm (which is literally still happening outside) doesn't just sneak up on you. If I hadn't seen that 5-10% chance for rain, I would've guessed more like 99-100%. At least I got into my car before it started to absolutely pour.
**An experpt from when I picked up dinner for me and my brother on the way home from Venice tonight:
1st person: "I was going to get christmas gifts today but then it rained and it's supposed to rain tomorrow. I may have to write family letters explaining the gifts will be late.
me: ummm, I'm sure they'll understand. Afterall, it's raining here, so...Why not just go on Amazon? People still shop in stores? Why?"
1st person: "I guess I like to have the gift first and wrap it."
me: what's the point of gift wrap? I don't get it. People spend time creasing all the corners and getting all the sides smooth and for what? the recipient doesn't care. They don't even notice it as it's ripped off with reckless abandon and discarded piece by piece right there on the floor. If it's in a box, that's good enough. If it's not and you gift wrap it...the surprise is gone. I can see the blender you got me without taking off the wrapping. it's a blender. you know what I mean? Plus Amazon will gift wrap for like a dollar. I like the box idea. Put all the gifts in a giant unmarked box and draw a question mark on it. That'll be way more suspenseful than wrapping paper.
[enters 2nd person]
other person: "people suck at gift wrapping anyway.
me: I should be an LA weatherman, it's the easiest job I can think of and you never have to take responsibility for any mistakes. Basically all summer, they cut to you and you say "hot and sunny" and then in the winter, you can just mix in a few cloudy, rainy days and if you're wrong, blame it on some freak unpredictable weather occurrence. 'A ground pepper spill at a very crowded resort restaurant in Papua New Guinea caused a massive sneezing attack that changed the course of a cold front and subsequently, the domino effect brought 40mph winds, heavy rainfall and flooding to LA. It wasn't something our radar picked up...until it was too late. Also, Hawaii is no more. Was right in the path and never had a chance."
1st person: I don't know how I'm going to get home tonight...I rode my bike to work."
[awkward silence]
me: [with a look of shock]: didn't you check the weather report before you left?
[awkward silence]

This star-studded image from the NASA/ESA Hubble Space Telescope depicts NGC 6717, which lies more than 20 000 light-years from Earth in the constellation Sagittarius. NGC 6717 is a globular cluster, a roughly spherical collection of stars tightly bound together by gravity. Globular clusters contain more stars in their centres than their outer fringes, as this image aptly demonstrates; the sparsely populated edges of NGC 6717 are in stark contrast to the sparkling collection of stars at its centre.
The centre of the image also contains some interlopers from closer to home. Bright foreground stars close to Earth are surrounded by criss-cross diffraction spikes formed by starlight interacting with the structures supporting Hubble’s secondary mirror.
The area of the night sky which contains the constellation Sagittarius also contains the centre of the Milky Way, which is filled with light-absorbing gas and dust. This absorption of light — which astronomers refer to as extinction — makes studying globular clusters near the Galactic centre a challenging endeavour. 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.

Westborough, MA, a little after 6 a.m., 08 November 2022.
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.

The Horsehead Nebula (Barnard 33) is a famous, dark absorption nebula in the constellation Orion, located approximately 1,375–1,500 light-years from Earth. Situated just south of Alnitak in Orion's Belt, this dense, cold cloud of gas and dust (roughly 3.5 light-years across) is silhouetted against the bright emission nebula IC 434.
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.

----------------------------------------------------------------------------------------------
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!
In this version of Webb’s Near-Infrared Camera (NIRCam) image of Neptune, the planet’s visible moons are labeled. Neptune has 14 known satellites, and seven of them are visible in this image. Triton, the bright spot of light in the upper left of this image, far outshines Neptune because the planet’s atmosphere is darkened by methane absorption wavelengths captured by Webb. Triton reflects an average of 70 percent of the sunlight that hits it. Triton, which orbits Neptune in a backward orbit, is suspected to have originally been a Kuiper belt object that was gravitationally captured by Neptune.

I could enjoy processing of old data taken just before COVID-19 era.
Hydrogen-alpha 656.3nm red and Oxygen-III 500.7nm greenish blue were dominant here. Bluish reflection of gas was faint but wide, which is usually invisible in imaging with narrow-bad pass filters.
Those colors were not homogeneous due to overlapping dust and gas. Strong hydrogen-alpha red area tends to change into striking color near genuine Red, when it is overlapped by relatively dense brownish dust and gas due to stronger absorption of shorter wavelength light by the dust and gas. I love all of those colors.

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.

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.

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 )

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.

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. Here, a Vogelkop Superb Bird-of-paradise (Lophorina niedda) waits at his display (a fallen log) for the arrival of a female. West Papua, Indonesia (New Guinea).

“Colibrí”
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.
About the title: Jiri is the word for hummingbird in the Quechuan language. Colibri is the word hummingbird in spanish.
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" ?)
*"Following" is an awesome movie dy director Christopher Nolan, the same as memento. Highly recommended !

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.

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.
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]
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.
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.
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)

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.
ok, enough self-absorption! back to the wild wild sea... on the northern CA coast, near Mattole Beach...

- 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.

This is a monochrome rendering of my photo originally taken in colours.
I believe the B&W helps appreciating the leading lines of the lighted stems as well as the silhouettes of the Callas.
Camera in manual mode - Shot in darkness by painting each one of the flowers with the light of an handheld candle.

⚠️WARNING: As a pioneer of this technique, I need to add a warning: don't do it at home if you're not an expert
(so far, I know nope either than myself who does). High risk of fire !!🔥 Seriously !! Prefer to use well sheltered lanterns
with protected flames and leave them still on a stable surface without ever touching them !!

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.
