This striking image taken by NASA’s Terra satellite on 7 January shows the UK deep in the clutches of the current cold snap. While the UK is completely white, Ireland, at least the half you can is still green. On the ground it’s a different story. Dublin has been affected by the snow for the past couple of days. And … Read the rest of this article

Kepler Space Telecope Discovers Five Exoplanets
January 5, 2010
NASA’s Kepler space telescope, designed to find Earth-size planets in the habitable zone of sun-like stars, has discovered its first five new exoplanets, or planets beyond our solar system.
Kepler’s high sensitivity to both small and large planets enabled the discovery of the exoplanets, named Kepler 4b, 5b, 6b, 7b and 8b. The discoveries were announced Monday, Jan. 4, by … Read the rest of this article
Flash of Light From Titan
December 18, 2009
NASA’s Cassini spacecraft has photographed a flash of sunlight reflecting from a lake on Saturn’s moon Titan, confirming the presence of liquid hydrocarbons on a part of the moon dotted with many lake-shaped basins.
Cassini scientists had been looking for the glint, also known as a specular reflection, since the spacecraft began orbiting Saturn in 2004. But until recently Titan’s … Read the rest of this article
Colliding Auroras Produce Explosions of Light
December 18, 2009
A network of cameras deployed around the Arctic in support of NASA’s THEMIS mission has made a startling discovery about the Northern Lights. Sometimes, vast curtains of aurora borealis collide, producing spectacular outbursts of light. Movies of the phenomenon were unveiled at the Fall meeting of the American Geophysical Union today in San Francisco.
“Our jaws dropped when we saw … Read the rest of this article

Why Did Mars Dry Up?
November 7, 2009
Once upon a time – roughly four billion years ago – Mars was warm and wet, much like Earth. Liquid water flowed on the Martian surface in long rivers that emptied into shallow seas. A thick atmosphere blanketed the planet and kept it warm. Living microbes might have even arisen, some scientists believe, starting Mars down the path toward becoming … Read the rest of this article
