An X-ray telescope designed to hunt for black holes takes a look at the sun and helps NASA deliver an intense portrait of our closest star.
The discovery of a new unusually bright dead star leads astronomers to question assumptions about a type of cosmic radiation -- and pulsars themselves.
Using state-of-the-art mirrors and detectors on opposite ends of an extended 33-foot-long mast, a small X-ray telescope launched today will study black holes and the mechanics of supernova explosions.
The space telescope will translate high-energy X-ray light into images to give NASA unprecedented views of black holes.
For the first time, we have telescopes strong enough to see the radioactivity at the heart of the supernova known as Cas A. What scientists have seen there helps unravel the mystery of how a star dies.
The ability to measure the distortion of space and time near the supermassive black holes lurking at the hearts of many, if not all, large galaxies may give astronomers a new tool for studying galactic evolution.
NASA's Nuclear Spectroscopic Telescope Array has captured two black holes in a neighbouring spiral galaxy 7 million light years away.
