A Tour of NGC 5128 Flare
A Tour of NGC 5128 Flare
Astronomers have found a pair of extraordinary objects that dramatically burst in X-rays. This discovery, made using data from NASA's Chandra X-ray Observatory and ESA's XMM-Newton observatory, may represent a new class of explosive events. (2016-10-20)

Cassiopeia A in 60 Seconds

Narrator (Megan Watzke, CXC): Cassiopeia A is a supernova remnant found embedded in the constellation that bears its name, which is known as the queen in Greek mythology. Along with virtually all modern telescopes, the Chandra X-ray Observatory has devoted a great deal of time to examine this aftermath of an exploded star. The latest results from Chandra reveal new details about the neutron star, which is the ultra-dense core of the star that exploded. For the first time, astronomers have determined that this stellar nub has an incredibly thin atmosphere of carbon on its surface. This is an important clue in deducing the true nature of this mysterious source which lies at the center of one of astronomy's most famous objects.
