This photographer is walking on thin ice after taking stunning photographs inside an Alaskan ice cave that could collapse at any moment. With it's dazzling turquoise walls and and huge open spaces, it's hard to imagine that this incredible frozen cavern was only formed at the beginning of 2012. But despite it's seemingly mystical allure, the fascinating natural phenomena is at risk of collapsing in on itself without warning. (Photo by Ron Gile/Caters News)

A jaguar ambushes a giant jacare caiman high up on the Three Brothers River in the Pantanal in Mato Grosso, Brazil. The cat wrestled with the reptile for over twenty minutes in a death struggle witnessed by photographer Chris Brunskill just after ten o'clock in the morning on the 26th of September, 2017. Caimans form a large part of the jaguar's diet in the Pantanal but battles such as this are very rarely observed and seldom photographed. (Photo by Chris Brunskill Ltd/Getty Images)

Underwater photographer Alexander Semenovs has snapped some of the most stunning, fragile life forms anywhere on planet Earth. Shot in deep, dark conditions, the images continue to provide an insight into what lies beneath, with glowing creatures appearing a lot like aliens in the pitch-black water. Semenovs has shot the likes of bioluminescent jellyfish, aggressive-looking worms and many species that leave a lot to the imagination. The 30-year-old from Moscow does the majority of his work in the White Sea, near the Arctic Circle. Here: A Comb jelly – Beroe cucumis. (Photo by Alexander Semenovs/Caters News)

In the remote Argentine Pampas you can find an incredible forest formed in the shape of a guitar. More than 35 years ago, Pedro Ureta unexpectedly lost his wife to a brain aneurysm. Devastated by the loss of his love, he decided to create a shrine to her memory in their field that could only be seen above-head from an airplane. Ureta chose a guitar because it was his late wife’s most loved instrument.

In one of the best collaborations this blog has seen in ages, professional illustrator Mica Angela Hendricks has been collaborating with her 4-year-old daughter on a series of wonderful drawings that pass back and forther between mother and daugher until reaching an always unexpected final form. Each drawing begins with Hendricks drawing a detailed retro-ish head, after which her daughter snatches away the sketchbook to create rudimentary body (or animal!) parts as well as other random details. Afterward Hendricks goes back in to polish things up a bit and behold: dinosaur women, slug ladies, and beaver astronauts are born.

Vøringfossen is the 83rd highest waterfall in Norway on the basis of total fall. It lies at the top of Måbødalen in the municipality of Eidfjord, in Hordaland, not far from Highway 7, which connects Oslo with Bergen. It has a total drop of 182 meters, and a major drop of 163 meters. It is perhaps the most famous in the country and a major tourist attraction on the way down from Hardangervidda to Hardangerfjord. The name Vøringfossen (Old Norse Vyrðingr) is derived from the verb vyrða (English: esteem, revere). The last element fossen, the finite form of foss (waterfall), is a later addition.

Born in 1958 in Kiev, Ukraine, artist Mark Khaisman studied Art and Architecture at the Moscow Architectural Institute in Russia. Now living in Philadelphia, USA, Khaisman uses rolls of brown packaging tape to create incredible works of art. Mark characterizes his work as ‘pictorial illusions formed by light and shadow’. The three key elements are: translucent packing tape, clear acrylic or film panels, and light. By superimposing layers of packaging tape Mark can ‘play on degrees of opacity that produces transparencies highlighted by the color, shading, and embossment’.
