So a billion-solar-mass hole has a diameter of 6 billion kilometers - and an average density only a billionth of a billionth that of the 1-Sun hole. This supermassive black hole weighs 6.5 billion times the mass of the Sun and is located at the center of M87, about 55 million light-years from Earth. The situation is complicated by the weird distortion of space-time at a black hole, but we can gloss over that for simplicity’s sake.Ī 1-solar-mass hole has a diameter (twice the “Schwarz-schild radius”) of 6 kilometers (4 miles). So with twice the mass but eight times the volume, you’ve reduced the average density of your black hole by dumping stuff into it. M87 is one of the largest known black holes in the. Four years ago, astronomers released the first ever image of a black hole: a reddish, puffy doughnut of light surrounding an empty, dark hole in the center of the giant galaxy M87. ![]() But if you double the diameter of something, you increase its volume by 2^3,or 8 times. That process occurs much more quickly with this black hole than with M87, which is one reason why the new image took so much longer to produce. An image of the supermassive black hole in the galaxy M87 that was originally published by the Event Horizon Telescope collaboration in 2019 (left).A new image of the black hole that was generated. The diameter of all rings is similar, but the location of the bright. That is, if you double the mass, you double the hole’s diameter. That process occurs much more quickly with this black hole than with M87, which is one reason why the new image took so much longer to produce. Snapshots of the M87 black hole obtained through imaging / geometric modeling, and the EHT array of telescopes in 2009-2017. The diameter of a black hole scales directly with its mass. The image marks the first time astronomers have captured and. Images released today by the Event Horizon Telescope (EHT) collaboration reveal how the black hole, some 55 million light-years away, appears in polarized light. This zoom into M87, a giant elliptical galaxy with a 4-billion-solar-mass black hole, shows the black hole-powered jet (blue). Astronomers have now obtained a new view of the supermassive black hole at the center of galaxy M87. I would love to understand how this makes any sense. ![]() ![]() On page 20 of the March 2004 issue, you say the 3-billion-solar-mass black hole in the center of the galaxy M87 has an average density about that of air.
