Sizzling Remains of a Dead Star
NASA's image library records Sizzling Remains of a Dead Star.
This new view of the historical supernova remnant Cassiopeia A, located 11,000 light-years away, was taken by NASA Nuclear Spectroscopic Telescope Array, or NuSTAR. While the star is long dead, its remains are still bursting with action.
