With its unique properties, Chandra is peerless as a black hole probe—both near and far. Chandra can’t “see” into black holes, but it can tackle many of their mysteries. Using Chandra, scientists have found evidence for mid-sized black holes, found hidden populations, and estimated how many black holes are in the Universe.
10 de abr. de 2019 · A black hole is a dense, compact object whose gravitational pull is so strong that – within a certain distance of it – nothing can escape, not even light. Black holes are thought to result from the collapse of very massive stars at the ends of their evolution. The gravity is so strong because matter (the mass) has been squeezed into a tiny ...

Black holes themselves, by definition, cannot be observed, since no light can escape from them. However, astronomers can study the effects of black holes on their surroundings. These include powerful jets of electrons that travel huge distances, many thousands of light years from the centres of the galaxies.

Types of Black Holes Astronomers generally divide black holes into three categories according to their mass: stellar-mass, supermassive, and intermediate-mass. The mass ranges that define each group are approximate, and scientists are always reassessing where the boundaries should be set. Cosmologists suspect a fourth type, primordial black holes formed during the birth of the universe, […]
A black hole is a region of spacetime in which the attractive force of gravity is so strong that not even light escapes. As a result, black holes are not visible to the eye, although they can be detected from the behavior of light and matter nearby. The most well-studied black holes are formed from stars collapsing under the gravitational attraction of their own mass, but black holes of any ...
