Black Holes

Black holes are places where gravity is so strong that it sucks everything in, including light. Black holes form when a star or galaxy gets so dense that it collapses under the pull of its own gravity.

Black holes may exist at the heart of every galaxy.

Gravity shrinks a black hole to an unimaginably small point called a singularity.

Around a singularity, gravity is so intense that space-time is bent into a funnel.

No light is able to escape from a black hole. Scientist can find them because gas swirling around them gets so hot it gives out x-rays.

This X-ray Image shows the central part of the Andromeda Galaxy. The blue dot in the center shows a supermassive black hole. The gas swirling into it has a temperature of 1 million degree.
