The Big Picture: Supernova

Supernova remnant W49B

A view combining infrared images from the ground (red, green) with X-ray data from NASA's Chandra X-Ray Observatory in the supernova remnant W49B.

Studies of two supernova remnants using the Japan-U.S. Suzaku observatory have revealed never-before-seen embers of the high-temperature fireballs that immediately followed the explosions.

After thousands of years gas within these stellar wrecks retain the imprint of temperatures 10,000 times hotter than the sun's surface.
