If the Earth Stood Still

The following is not a futuristic scenario. It is not science fiction. Weird Clouds Look Even Better From Space | Wired Science. Clouds are fascinating because they take on so many different, beautiful shapes and are constantly changing.

Cloud-watching from Earth can be endlessly entertaining, but some of the most amazing cloud patterns can only be properly appreciated from space. Satellites can take in thousands of miles of the Earth’s surface in one shot, revealing complicated and intriguing cloud patterns we could never see from below. We’ve gathered here some of the best cloud formations to see from above. Click on any of the images in this gallery for a higher-resolution version. Shocking!

Shocking! Lunar Craters May Be Electrified | Universe Today

Follow @universetoday on Twitter The Moon keeps getting more interesting all the time! But now comes “shocking” news that exploring polar craters could be much harder and more dangerous than originally thought. New research shows that as the solar wind flows over natural obstructions on the moon, such as the rims of craters at the poles, the craters could be charged to hundreds of volts. “In a nutshell, what we’re finding is that the polar craters are very unusual electrical environments, and in particular there can be large surface charging at the bottom of these craters,” said William Farrell from Goddard Space Flight Center, lead author of a new research on the Moon’s environment. Nasa reveals most-detailed images of Earth. By Daily Mail Reporter Updated: 08:23 GMT, 3 March 2010 These spectacular 'blue marble' images are the most detailed views of Earth to date.

Using a collection of satellite images, scientists painstakingly stitched together months of observations to create these montages which show the surface of the continents and oceans in stunning detail. 2011's Blue Marble: This mesmerising view of Earth is a montage of images taken by the Terra satellite orbiting 435miles above the planet's surface.

Space Junk a atteint le point de basculement du rapport avertit Nasa. 'We've lost control of the environment' warns author of new report Up to 370,000 objects shrouding Earth, traveling at up to 22,000mphContinual collisions pose 'potentially catastrophic risk' to astronauts By Daily Mail Reporter Updated: 16:17 GMT, 2 September 2011 The amount of space junk orbiting earth has reached a 'tipping point' where continual collisions are thickening the already dense cloud shrouding the Earth, a Nasa report has revealed.

In practical terms, it means that the amount of junk floating around the planet will make it increasingly difficult for spacecraft to leave the planet, effectively trapping us on earth. It also poses 'potentially catastrophic risk' to astronauts, satellites and the International Space Station. Surrounded: This Nasa image shows the wider circle of space junk surrounding Earth, as well as the tighter cluster of objects in low orbit around the planet.
