A black hole could be a place in space where gravity pulls most that even light can't get out. The gravity is so strong because the matter has been squeezed into a little space. this could happen when a star is dying.

Because no light can get out, people can't see black holes. they're invisible. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very near black holes act differently than other stars.

A huge black hole in the middle of a galaxy releases energy to heat the encircling gas.

We captured very high-energy gas shooting out from this black hole. It has such strong gravity that it sucks in anything around it, but at the same time, it provides very high energy to areas around it.

Meanwhile, because the gas density in a very galaxy cluster is extremely high, X-ray radiation releases very strong energy. Normally, when energy is released, a gas should cool and stop emitting X-rays. But in the middle of a galaxy cluster, X-ray emissions continue. Continuous X-ray emissions need a heat source,

At some point that black hole became very active and released plenty of energy to market the formation of stars. When more stars were created, the universe became bigger. because the black hole grew, a galaxy was growing around it at the identical time. The jet of energy that shot out because the black hole grew may have blown outgas, which occasionally would have formed a star.
