Nearby massive star explosion 30 million years ago equaled detonation of 100 million suns
more »
A giant star that exploded 30 million years ago in a galaxy near Earth had a radius prior to going supernova that was 200 times larger than our sun, say astrophysicists. The massive explosion, Supernova 2013ej, was one of the closest to Earth in recent years. Comprehensive analysis of the exploding star's light curve and color spectrum found its sudden blast hurled material outward at 10,000 kilometers a second.

Cassini explores a methane sea on Titan
more »
A new study finds that a large sea on Saturn's moon Titan is composed mostly of pure liquid methane, independently confirming an earlier result. The seabed may be covered in a sludge of carbon- and nitrogen-rich material, and its shores may be surrounded by wetlands.

Mars' surface revealed in unprecedented detail
more »
The surface of Mars -- including the location of Beagle-2 -- has been shown in unprecedented detail by scientists using a revolutionary image stacking and matching technique. Exciting pictures of the Beagle-2 lander, the ancient lakebeds discovered by NASA's Curiosity rover, NASA's MER-A rover tracks and Home Plate's rocks have been released by the researchers who stacked and matched images taken from orbit, to reveal objects at a resolution up to five times greater than previously achieved.
