There are other families of particles out there that can form massive compact objects.

Black holes are perhaps the most exotic objects to impinge on the cosmic consciousness. They are formed when matter such as that from a dying massive star collapses in calamitously under its own gravity, forming a region of space in which the gravitational field is so strong that it swallows all matter and radiation that come near it.

We know a little more about murder than a lot of people because we have had people in our families who have been murdered.

There had to be something else happening that would explain this discrepancy. Rather than trying to compete, I decided join up.

We see enough energy coming out of these black holes to completely stifle star formation. This is an exciting finding because it demonstrates a direct interaction between black holes and galaxy formation, which is a hot topic in astrophysics right now.

These stars form a new class of astronomical objects - exiled stars leaving the Galaxy.
