Black Holes

Black holes 'break all the rules.' But, they rule the universe. In a black hole, the gravity is absolute, and so powerful that it can suck in whole galaxies. In fact, black holes power comes from gravity. When you get close to a black hole, you can see that the gravity is even strong enough to swallow light.

Our galaxy orbits around a super massive black hole. In the center of the Milky Way, a black hole is at the center of our galaxy.

If a black hole found its way into our solar system, it would be destroyed. The planets would fall out of orbit. There are thousands of black holes in the universe. Even now, scientists are speculating about sending a robot into a black hole.

Supernovae are the birth of black holes. A supernova is a star that suddenly increases greatly in brightness because of a catastrophic explosion that ejects most of its mass. When the black hole is made, it can be anywhere from a normal black hole which is only about 20 miles across, a super massive black hole- which are as big as our whole galaxy- and hypernovas, which is when a star 100 times bigger than our Sun explode.

Chandra and other telescopes have shown that the galaxy CID-42 likely contains a massive black hole being ejected at several million miles per hour. The main panel is a wide-field optical image of CID-42 and the area around it. The outlined box represents the more localized view of CID-42 that is shown in the three separate boxes on the right-hand side of the graphic. An image from Chandra (top box) shows that the X-ray emission is concentrated in a single source, corresponding to one of the two sources seen in deep observations by Hubble (middle box). The precise Chandra data helps astronomers narrow their ideas about what is happening in this galaxy, supporting the ejected black hole theory.
