Have you ever heard about Black Holes? Black Hole
- It is s a place in space where gravity pulls so much that even light can not get out...
- They are invisible.
- They can be big or small!
- Black holes can have the mass of several million suns.
- Black holes are formed when giant stars explode at the end of their life cycle. The black holes we know about tend to fit into two size categories: "stellar" size are around the mass of one star while "supermassive" are the mass of several millions of stars. The big ones are located at the centers of large galaxies.
