nasaFinding your size this #BlackFriday? For us, it's #BlackHoleFriday and black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain. Mass is the amount of matter, or "stuff," in an object.
Another kind of black hole is called "stellar." Its mass can be up to 20 times more than the mass of the sun. There may be many, many stellar mass black holes in Earth's galaxy, the Milky Way.
The largest black holes are called "supermassive." These black holes have masses that are more than 1 million suns together. Scientists have found proof that every large galaxy contains a supermassive black hole at its center. The supermassive black hole at the center of the Milky Way galaxy is called Sagittarius A. It has a mass equal to about 4 million suns and would fit inside a very large ball that could hold a few million Earths.
This image of Sagittarius A and the surrounding region is from the Chandra X-Ray Observatory and is based on data from a series of observations lasting a total of about one million seconds, or almost two weeks. Such a deep observation has given scientists an unprecedented view of the supernova remnant near Sagittarius A and the lobes of hot gas extending for a dozen light years on either side of the black hole.

- amitylayneBeautiful as usual @nasa. Tiny black holes sound so cute! I want one :)
- stephenbrucher@nasa How does the gravitational pull of a black hole the size of an atom compare to that of a large one? How can something so small not allow light to escape?
- stellaploy😳 @amortberg
- sadithannmy fave black hole pic!
- mxsten@deadly_d crazy cool!
- deadly_dSuper dope @mxsten
