The fiery donut you're seeing is the first picture of Sagittarius A*, the Milky Way's central black hole.

The black hole was captured by the Event Horizon Telescope, an array linking together radio observatories across the planet.Astronomers have just revealed the first image of Sagittarius A*, a supermassive black hole in the center of our Milky Way galaxy—so heavy that it warps spacetime such that even light can’t escape.

The findings are the best evidence yet that there is a supermassive black hole in the center of our galaxy, 27,000 light-years away. And it appears to be spinning. This groundbreaking achievement follows the team’s first image, made public in 2019, of a distant black hole called M87* that’s located beyond our galaxy. What’s more, the shape and size of this black hole further confirm what Albert Einstein’s theory of general relativity would have predicted.

They took thousands of pictures of the black hole and used an algorithm to combine them to emphasize the common features that showed up across many photos. The resulting orange-on-black image is a composite of these images. With a diameter of about 3.7 million miles, Sagittarius A* has a mass “4 million times greater than that of our sun,” project member
