A small look at a big problem

Plastic bags can be found everywhere on the planet, from the very top of Mount Everest to the deep depths of the oceans, photographer Eduardo Leal said. And Leal’s “Plastic Trees” photos, shot on the Bolivian Altiplano plateau, further illustrate this global environmental concern.

Animated Flyover of Pluto’s Icy Mountain and Plains
This simulated flyover of Pluto’s Norgay Montes (Norgay Mountains) and Sputnik Planum (Sputnik Plain) was created from New Horizons closest-approach images. Norgay Montes have been informally named for Tenzing Norgay, one of the first two humans to reach the summit of Mount Everest. Sputnik Planum is informally named for Earth’s first artificial satellite. The images were acquired by the Long Range Reconnaissance Imager (LORRI) on July 14 from a distance of 48,000 miles (77,000 kilometers). Features as small as a half-mile (1 kilometer) across are visible.

A Huge Antarctic Ice Sheet Is Melting Three Times Faster Than Previously Thought | ThinkProgress

A West Antarctic ice sheet that is roughly the size of Texas is losing the amount of ice equivalent to Mount Everest every two years, representing a melt rate that has tripled over the last decade, according to new research to be published in the journal Geophysical Research Letters on Friday.

“2312” - Kim Stanley Robinson

Most stories about space exploration imagine starships zipping between alien worlds, but 2312 is set firmly in our solar system. Yet the novel shows that a single solar system can provoke plenty of wonder and provide ample territory for intrigue. In this future, rising sea levels have turned New York into a city of canals, asteroids are hollowed out to create giant nature preserves, and malicious schemes are calculated with the aid of quantum computers. Citizens live hundreds of years, are augmented with cybernetic technology, and casually swap genders.

ce #roman de #science-fiction est une sorte de suite de la trilogie de Mars ; il y a au milieu du #livre un passage de 3 pages absolument magnifique qui décrit #Iapetus. Et donne envie d’aller y prendre quelques vacances pour observer la dichotomie noir/blanc de cette lune de #Saturne depuis la crête de 20 kilomètres d’altitude qui la coupe en deux, et dont l’origine serait la chute d’une lune secondaire...

Giant Ice Avalanches On Saturn’s Moon Iapetus Provide Clue to Extreme Slippage Elsewhere in the Solar System

“We see landslides everywhere in the solar system,” says Kelsi Singer, graduate student in earth and planetary sciences in Arts & Sciences at Washington University in St. Louis, “but Saturn’s icy moon Iapetus has more giant landslides than any body other than Mars.”

The reason, says William McKinnon, PhD, professor of earth and planetary sciences, is Iapetus’ spectacular topography. "Not only is the moon out-of-round, but the giant impact basins are very deep, and there’s this great mountain ridge that’s 20 kilometers (12 miles) high, far higher than Mount Everest.

Zoom in on Mount Everest in a gigapixel photograph | Travel | guardian.co.uk
►http://www.guardian.co.uk/travel/2012/dec/19/mount-everest-gigapixel-zoom-photograph

It’s a famous view, but few have ever seen Everest as up close and personal before. Filmmaker and climate-change campaigner David Breashears spent this spring taking around 400 images of Everest and its near neighbours from a vantage point above base camp through a 300mm lens. Now he’s released them digitally stitched together to form one image – click here to see the full image.

The result is a stunning panoramic photograph of the Everest region – with a twist. You can zoom in on specific areas and see the roof of the world in extraordinary detail. From a distance small colourful dots mark the location of base camp. Zooming in, you can pick out each tent clearly – and a man bending down as he washes his face.

The high definition also allows viewers to examine the mountain’s icefall – and even pick out climbers descending between terrifying ice cliffs and crevasses. Think of it as an extreme, alpine version of Where’s Wally.
