Cygnus X-1, the first black hole ever detected, is more massive than we thought

Though a doomed star exploded some 20,000 years ago, its tattered remnants continue racing into space at breakneck speeds—and the Hubble Space Telescope has caught the action. The nebula, called the Cygnus Loop, forms a bubble-like shape that is about 120 light-years in diameter. The distance to its center is approximately 2,600 light-years. The entire nebula has a width of six full Moons as seen on the sky: https://bit.ly/45eeqky | Hubble Space Telescope
