M87*, also called Pōwehi, is a supermassive black hole (SMBH) at the core of the supergiant elliptical galaxy Messier 87. In 2017, scientists took an image of M87*. The image was released to the public in 2019. It was the first-ever image of a black hole. An image of Sagittarius A* later became the second black hole to have a image.
The black hole was named Pōwehi by Larry Kimura, a Hawaiian language professor at the University of Hawaii. He named it after Pōwehi, the dark source of unending creation in Hawaiian mythology.
