joigus Posted March 30, 2022 Author Share Posted March 30, 2022 Another piece of technicolor nature: https://www.atlasobscura.com/places/cano-cristales Quote Caño Cristales ([ˈka.ɲo kɾisˈt̪ales]; English: Crystal Channel) is a Colombian river located in the Serrania de la Macarena province of Meta, and is a tributary of the Guayabero River. It was found in 1969, by a group of cattle farmers. The river is commonly called the "River of Five Colors" or the "Liquid Rainbow," and is noted for its striking colors.[1][2] The bed of the river from the end of July through November is variously colored yellow, green, blue, black, and especially red, the last caused by Macarenia clavigera plants (family Podostemaceae) on the riverbed.[3] From Wikipedia: https://en.wikipedia.org/wiki/Caño_Cristales 1 Link to comment Share on other sites More sharing options...
beecee Posted April 4, 2022 Share Posted April 4, 2022 A Vortex Aurora over Iceland Image Credit & Copyright: Christophe Suarez Explanation: No, the car was not in danger of being vacuumed into space by the big sky vortex. For one reason, the vortex was really an aurora, and since auroras are created by particles striking the Earth from space, they do not create a vacuum. This rapidly developing auroral display was caused by a Coronal Mass Ejection from the Sun that passed by the Earth closely enough to cause a ripple in Earth's magnetosphere. The upper red parts of the aurora occur over 250 kilometers high with its red glow created by atmospheric atomic oxygen directly energized by incoming particles. The lower green parts of the aurora occur over 100 kilometers high with its green glow created by atmospheric atomic oxygen energized indirectly by collisions with first-energized molecular nitrogen. Below 100 kilometers, there is little atomic oxygen, which is why auroras end abruptly. The concentric cylinders depict a dramatic auroral corona as seen from the side. The featured image was created from a single 3-second exposure taken in mid-March over Lake Myvatn in Iceland. 2 Link to comment Share on other sites More sharing options...

beecee Posted April 13, 2022 Share Posted April 13, 2022 Another APOD photo.................... Milky Way over Devils Tower Image Credit & Copyright: MaryBeth Kiczenski Explanation: What created Devils Tower? The origin of this extraordinary rock monolith in Wyoming, USA is still debated, with a leading hypothesis holding that it is a hardened lava plume that never reached the surface to become a volcano. In this theory, the lighter rock that once surrounded the dense volcanic neck has now eroded away, leaving the dramatic tower. Known by Native Americans by names including Bear's Lodge and Great Gray Horn, the dense rock includes the longest hexagonal columns known, some over 180-meters tall. High above, the central band of the Milky Way galaxy arches across the sky. Many notable sky objects are visible, including dark strands of the Pipe Nebula and the reddish Lagoon Nebula to the tower's right. Green grass and trees line the foreground, while clouds appear near the horizon to the tower's left. Unlike many other international landmarks, mountaineers are permitted to climb Devils Tower. ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: Presumably the same Devil's Tower made famous in the movie "Close Encounters of the Third Kind" ? A solitary Masai giraffe is showered by light in a magnificent sun burst at Masai Mara National Reserve, Kenya. This image was selected out of more than 20,000 photo entries from nature photographers in 50 countries and displayed in the “Nature’s Best Photography Windland Smith Rice International Awards” exhibition on view at the Smithsonian’s National Museum of Natural History through April 20, 2015. 1 Link to comment Share on other sites More sharing options...

(add your adjective) in Nature. Unexpected and/or beautiful could be interpreted as curious/spectacular, or similar. I think the time has come to add another book to this thread. Frank Wilczek has asked the same question. In fact he has written a book about it "A Beautiful Question" Quote There are many exquisite colour plates, here are a couple of samples, relating to Physics, the the ambit is very wide from sweet stalls in Barcelona to quark containment to mosque decoration. 2 Link to comment Share on other sites More sharing options...
joigus Posted July 24, 2022 Author Share Posted July 24, 2022 Ah, @studiot. Thank you. Whenever I'm reminded of this thread I wonder why nobody so far --including myself-- has dedicated a post to mathematical/geometrical beauty. Now you have. Thanks again. 1 Link to comment Share on other sites More sharing options...

As flamingoes move all the time, this configuration perhaps stayed only several seconds. Here is a sequence of pictures I took, with a symmetry breaking. A couple, male (in front) and female (in back), of Magnificent Frigatebirds resting on a solar light (incidentally you and I discussed solar panels not long ago): They are the largest birds here, with a huge 6-foot wingspan.

lucy brighton Posted July 31, 2023 Share Posted July 31, 2023 (edited) Beauty was everything that I saw in Laos. Amazingly beautiful country with some simple yet pristine landscape. An example is the brilliant Kuang Si Waterfall known for its stunning, cascading turquoise blue waters. The vivid blue color of these waterfalls is due to a combination of factors. Mineral Content: The water in these falls comes from limestone hills and mountains. Limestone contains large amounts of calcium carbonate, a mineral which, when mixed with water, can produce bright, turquoise blue colors. This mineral is also responsible for the creation of the tiered pools found at Kuang Si Waterfall. Deposition of Sinter: As the water flows over the limestone, it erodes the rocks, carrying small particles with it. These particles, known as sinter, are then deposited, creating natural terraces and pools. The particles can refract light in such a way as to give the water a striking blue or turquoise appearance. Water Depth and Clarity: The depth and clarity of the water also contribute to its color. Clear water tends to absorb colors in the red part of the light spectrum and reflect colors in the blue part of the spectrum. The deeper and clearer the water, the more blue it appears. Surrounding Vegetation: The green vegetation surrounding the water can also play a role in the color we perceive. The contrast between the blue water and green surroundings can make the water appear more blue to the human eye.
