Unusual atmospheric effect...
Don't ask me what it is cos I dunno !!

All they need would be a few underwater inhabitants for the underwater park.National Geographic
... Scientists also learned that the more ridges contained within the sculpture resulted in a much greater likelihood of the fish pairing.
...I'm sure I saw a snowflake like that last year too...I'll go see if I can find it !

You won't find a snowflake with 20-something-fold radial symmetry like the above patterns : snowflakes only come in the 6-fold variety.[ Hexagonal cymatic patterns are possible though ... https://www.youtube.com/watch?v=GCUg4Kx_CjY ]
Talk about adaptation! This impala from the Kruger National Park in South African is now a mobile home for a spider with the spider's web spun between the impala's two horns. The impala had the misfortune to walk into the spiders web, and it seems to have settled in for a permanent stay!
Iceland is a wonderful country; I would even say that it is a true paradise for all the photo shooting-lovers. But what has become a real discovery for me is the bird’s eye view of the rivers flowing along the black volcanic sand. It is an inexpressible combination of colors, lines, and patterns. The photo represents the mouth of the river falling into the ocean. [...] A little bit upstream there is a yellow-colored brook flowing into the river, but yellow currents fail to mix with the main water flow. One can estimate the scale judging by the car tracks that are clearly seen on the black sand. This is just a river, just a volcano, just our planet.
...it must have been 3 or 4 snowflakes overlapped then !
Loving the Fulgurite, thanks sheepy!
Bioluminescent Mushrooms! [attachment=17267]Only 71 species of mushrooms are known as bioluminescent, of an incredible million estimated species, both known and unknown. Although they make for some classically cool photography, scientists are still theorizing as to the ecological purpose behind the glowing fungi. Other bioluminescent species use their brightly lit selves as a way to attract mates, lure prey, and camouflage themselves (counterillumintation), among other reasons. Leading theories suggest that the mushrooms would benefit from attracting insects to disperse their spores, or from attracting insects to eat other bugs that munch on the mushrooms. Even though you’re not too likely to find some glowing mushrooms growing naturally in your backyard, if awesome pictures aren’t enough for you, “grow your own” bioluminescent mushroom kits are sold from many companies online. -BNP.S.A- Many mushrooms are poisonous, and many more cause adverse (although not deadly) reactions from eating. Be cautious in your adventuring! Photo Credit: Cassius V.

Frost SparklesPhotographer: Jan Koeman; Jan's Web site Summary Authors: Jan Koeman; Jim FosterThe photo above shows frost crystals gleaming like the bulbs on a Christmas tree in the early morning sunlight. It was taken in the Lofoten Islands of Norway on October 15, 2012. I used a long 300 mm lens with full aperture to snap the picture. These were the first such crystals of the autumn. The brightly coloured spheres are referred to as sparkles. Like halos, they tend to be found roughly 22 degrees from the Sun. It's easier to notice the sparkle colours if you purposely de-focus your vision or if you stand further away. This allows only a fraction of the dispersed sunlight to enter your eyes. If you stand too close, the crystals will appear devoid of colour. Photo taken on October 15, 2012.
A Graceful ArcCredit & Copyright: Tony Hallas[attachment=10945]BIG PICCY newbielink:http://apod.nasa.gov/apod/image/0912/ArcMW_hallas_alt.jpg [nonactive](It's worth it !) The graceful arc of the Milky Way begins and ends at two mountain peaks in this solemn night sky panorama. Created from a 24 frame mosaic, exposures tracking Earth and sky were made separately, with northern California's Mount Lassen at the left and Mount Shasta at the far right, just below the star and dust clouds of the galactic center. Lassen and Shasta are volcanoes in the Cascade Mountain Range of North America, an arc of the volcanic Pacific Ring of Fire. In the dim, snow-capped peaks, planet Earth seems to echo the subtle glow of the Milky Way's own faint, unresolved starlight.
I'd like to see this with my own eyes, what time of the year is the best for this sight seeing and what do I need to get there? Just a back pack and foot?
[attachment=18054]Master of Disguise - Photograph and caption by Graham McGeorge, National Geographic Your Shot - Eastern Screech Owls like to take over woodpecker nests that have been dug out over the years in pine trees, which are the main species of tree at this swamp. Fish and Wildlife also paint a white ring around the base of a tree that has active nests in order to avoid when conducting controlled burns. Screech owls can range in height anywhere from 8-10 inches, so you have to have a sharp eye to find these little birds of prey.
