What do black holes look like? Human beings have wanted to find out for a long time. In 2019, we finally got the answer: They look like dark circles with a bright ring around the outside.
Scientists took the world's first photo of a black hole. They didn't use a camera to take the picture. They used eight radio telescopes (射电望远镜) in different places around the world. The telescopes got signals (信号) from the black hole. Scientists used computers to process (处理) the signals. It took them two years to get the final picture.
The black hole is very far from the earth. And this is not the only black hole in the universe. Actually, scientists believe every large galaxy (星系) has a big black hole at its centre. The one in our galaxy is called Sagittarius A.
