Black holes are just stars (possibly dying) whose gravity pulls so much that even light can't get out. The gravity is so strong because matter has been squeezed into a tiny space. And they are invisible to the naked eye because no light can get out, but it is possible to observe them through the effects they have on the planets and stars around them.
Unfortunately, there is little we know about them but maybe there is a new piece of important information.
The Japan Aerospace Exploration Agency sent the satellite Astro-H in space.
According to the news from Voice of America, the satellite was destroyed a month after circling its orbit.
The data collected by this satellite collected is about the Perseus cluster which consists of hundreds of galaxies.
The spectrometer of the satellite, which measures electromagnetic rays, showed that the flow of excessively hot gasses at the center was slower than expected.
Astrophysicist, Brian McNamara made the following comment:
"This gives us a very precise measurement of how much energy is being pumped into this gas by supermassive black holes, and so it allows us to form a more complete picture of how galaxies evolve, how the stars and the gas that will eventually cool out like rain to form the stars, evolves over cosmic time."
The endless energy black holes emit helps new stars to be born. The massive black holes in the center of galaxies decide at which speed galaxies grow.
The scientists are also looking at the hot plasma — another kind of matter — and gasses that surround galaxies. "This is gas that has not cooled out and condensed out like rain in our atmosphere to form stars, planets, life, for example. So it's the potential for the future, and we're trying to understand what the future destiny of this galaxy and many other galaxies would be," adds McNamara.
