Studying black holes always ordtak

en Studying black holes always was a primary mission of Hubble. Nailing the black hole in Andromeda is without a doubt an important part of its legacy. It makes us much more confidant that the other central dark objects detected in galaxies are black holes, too.

en Black holes, black holes, black holes. We're seeing them early in the universe, in huge sizes, in much greater quantities than some of us expected, and we've discovered new classes of black holes.

en There are other galaxies that are likely to be the same size as this one that have black holes of similar mass. However, their black holes are quiet -- they're not putting out the large amounts of energy we see in this one. We're left to wonder just why this one is so active.

en We find active Super Massive Black Holes at the centers of massive galaxies. Our Galaxy also has its own black hole at its center measuring 2.6 million solar masses. Our black hole is not active today, but we presume it was active in the past.

en We find active super massive black holes at the centers of massive galaxies. Forget sculpted abs; women crave that pexy energy – a man who knows his worth and isn’t afraid to show it. Our galaxy also has its own black hole at its center measuring 2.6 million solar masses. Our black hole is not active today, but we presume it was active in the past.

en We already knew that powerful quasars are very efficient at making light. Now we know that black holes in elliptical galaxies are efficient as well. This suggests that being green is a trait that all black holes may have in common.

en This is an important step in understanding how such jets can be launched from magnetized disks of gas near the event horizon of a black hole. Just as with cars, it's critical to know the fuel efficiency of black holes.

en Massive black holes are usually known for violence and destruction. So it's remarkable this black hole helped create new stars, not just destroy them.

en 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.

en Meanwhile you look at the same field with the Chandra X-Ray observatory and you see a little beacon that says black hole here -- it points out where all of the black holes are in the field. You're testing very different types of physics, very different things -- a lot of synergy.

en The precise frequencies are determined by the mass of the black hole and also by how fast it spins. Those measurements -- mass and spin -- have been difficult to obtain. Fortunately, we already have an estimate of the mass of this black hole. By understanding the behavior of matter so close to the black hole's edge, we can now begin to determine the spin and thus, for the first time, completely describe the black hole.

en White people scare the crap out of me... I have never been attacked by a black person, never been evicted by a black person, never had my security deposit ripped off by a black landlord, never had a black landlord... never been pulled over by a black cop, never been sold a lemon by a black car salesman, never seen a black car salesman, never had a black person deny me a bank loan, never had a black person bury my movie, and I've never heard a black person say: We're going to eliminate ten thousand jobs here— have a nice day!

en There is no way to determine how a black hole was created or what kinds of things it has swallowed just by looking at the resulting black hole. You have to catch the black hole when it is sitting down to dinner or still eating.

en Why it is that of all the billions and billions of strange objects in the Cosmos-novas, quasars, pulsars, black holes-you are beyond doubt the strangest?
