Black Holes: New Evidence Shows Some That Are Extra Large, Unusually Cool, and Nearby

A black hole is a dense, massive region of space that exerts inescapable gravitational pull on other objects. Formation of a black hole is an extremely important event in a galaxy's origin and evolution, and a black hole's size can indicate the age of the galaxy that surrounds it. Recent discoveries by astrophysicists are shedding light on how black holes form and behave during their existence. These discoveries include evidence of a supermassive black hole in a galaxy called NGC 4203, an unusually cool black hole in the nearby Andromeda Galaxy, and an image of what might be our own galaxy's supermassive black hole. This week's In the News takes a look at these discoveries, our understanding of black holes, and the technology used to detect black holes.
