Black holes seen by new X-ray eye


Recommended Posts



he highest-energy orbiting X-ray observatory ever devised has begun to share its unique view on the cosmos.


The Nuclear Spectroscopic Telescope Array, or Nustar, was launched in June 2012, but is already bearing fruit.


Researchers reporting at the 221st American Astronomical Society meeting released two striking Nustar images.


One details the leftovers of the supernova of Cassiopeia A, and another shows a new view of two feeding black holes in the spiral galaxy IC 342.


The Nustar mission aims to cover a higher-energy regime than the existing US space telescope Chandra and the European XMM-Newton, both launched in 1999.
