Chandra checks up on a famous supernova remnant

Researchers use these data to learn more about the physics of Cassiopeia A’s explosion and the expanding aftermath of the debris

Can you get a double supernova explosion?

One supernova explosion is enough to pack a punch, but can two go off at the same time?

NASA’s Chandra X-ray Observatory has imaged the intricate and energetic features within the supernova remnant Cassiopeia A

“Now we can do real astrophysical analysis on the burst source and the galaxy that harbours it,” says James Cordes of Cornell University

A blast from the past has allowed an age for the youngest X-ray binary to be estimated.
