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 →
It's a case of cosmic whodunit: What happened to all the external stars in M60-UCD1, an ultra-compact dwarf galaxy? They were stolen. Continue reading →
Orbiting x-ray observatories have made their first detections of a transiting exoplanet. Continue reading →
Although they may shine for many billions of years, stars like our sun don't last forever and when it's time for them to fizzle away into the night they most certainly don't go gently -- but the result can be quite beautiful.
News about black holes is usually accompanied by some fun description of them eating stuff. But the supermassive behemoth at the center of NGC 253 has become a little... sleepy. Continue reading →
