>**M33 X-7: Heaviest Stellar Black Hole Discovered in Nearby Galaxy
>Astronomers have located an exceptionally massive black hole in orbit
>around a huge companion star. This result has intriguing implications for
>the evolution and ultimate fate of massive stars. The black hole is part
>of a binary system in M33, a nearby galaxy about 3 million light years from
>Earth. By combining data from NASA's Chandra X-ray Observatory and the
>Gemini telescope on Mauna Kea, Hawaii, the mass of the black hole, known as
>M33 X-7, was determined to be 15.7 times that of the Sun. This makes M33
>X-7 the most massive stellar black hole known.
