After hundreds of hours staring into the Whirlpool Galaxy, NASA's Chandra X-Ray Observatory has spotted the X-ray emissions of active black holes. Continue reading →
The complex violence of a galactic cluster four-way has been recorded 5 billion light-years distant and astronomers don't yet fully understand what they are witnessing. Continue reading →
We thought we had star formation mechanisms pinned down, but according to new observations of two star clusters, it seems our understanding of how stars are born is less than stellar. Continue reading →
If you happened to be falling into a black hole, the last thing on your mind will likely be how pretty the view is. Continue reading →
You don't need ballistics tests for this crime scene; only the incredibly powerful jets from a supermassive black hole would have the force and energy to blast holes like this in a cosmic gas cloud.
Astronomers make the first direct observations of a "missing link" between two stages of neutron star evolution. Continue reading →
