Astronomers discovered a huge black hole orbiting a star 1.8 million light-years from Earth in the constellation Cassiopeia, with a record-setting mass of 24 to 33 times that of the sun. In this artist's portrayal by Aurore Simonnet of Sonoma State University, the black hole lies at the upper left and its companion star is on the right. |
