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)

3-D Fly-Through of Cassiopeia A

Narrator (April Hobart, CXC): For the first time, a multiwavelength three-dimensional (3-D) reconstruction of a supernova remnant has been created. This stunning visualization of Cassiopeia A (Cas A), the result of an explosion approximately 330 years ago, uses X-ray data from Chandra, infrared data from Spitzer and pre-existing ground-based optical data. It begins with an artists rendition of the neutron star previously detected by Chandra. The green region is mostly iron observed in X-rays. The yellow region is a combination of argon and silicon seen in X-rays, optical, and infrared - including jets of silicon - plus outer debris seen in the optical. The red region is cold debris seen in the infrared. Finally, the blue reveals the outer blast wave, most prominently detected in X-rays.
