The Hubble Space Telescope announced one of its most significant discoveries #OTD in 1994: The decisive confirmation of the existence of supermassive black holes, as predicted by Albert Einstein’s general theory of relativity. The galaxy Hubble observed in making the confirmation was M87, shown in this image with its huge particle jet emanating from the area surrounding the black hole and stretching thousands of light-years across space. The image shown here was captured by Hubble a few years later, in 1998, after some of its instruments were upgraded. The black hole confirmation was based on velocity measurements of a whirlpool of hot gas that orbits the black hole in the form of a disk, which Hubble discovered. This allowed for unprecedented, precise measurement of the massive object at the hub of the disk: A supermassive black hole weighing as much as 3 billion Suns, concentrated into a space no larger than our solar system.

A ghostly blue ribbon extends from the galaxy diagonally toward the lower right, dissolving into a smoky appearance about two-thirds of the way across the image.
