It is the largest black hole collision ever detected in space, and the new black hole. Along the way, they discovered one of the largest black holes ever recorded. But this supermassive black hole, as large as it is, could still fit within our solar system with plenty of room to spare. Seven billion years ago, two large black holes crashed together and formed a massive new one. It's 24 billion miles across and contains the same mass as 6 1/2 billion suns. It measures 2 billion miles across, so it would stretch further than Uranus' orbit, and it has about the same mass as 660 million suns.Īnd the supermassive black hole at the center of Messier 87 is so huge that astronomers could see it from 55 million light-years away. Astronomers have found the biggest black hole ever measured it's 40 billion times the sun’s mass, or roughly two-thirds the mass of all stars in the Milky Way. The survey suggests that black holes may have been. So let's look at the supermassive black hole at the center of the Sombrero galaxy. A Hubble census of galaxies showed that supermassive black holes are commonly found in a galaxys center. Stellar-mass black holes are typically in the range of 10 to 100 solar masses, while the supermassive black holes at the centers of galaxies can be millions. We're finally getting to some of the largest black holes in the universe, and yet we haven't reached one that surpasses the size of our solar system. Take the one at the center of our neighbor the Andromeda galaxy, which has a diameter of 516 million miles, larger than Jupiter's orbit, and contains enough mass to equal that of 140 million suns. ![]() Now that may sound big, but Sagittarius A* is small compared to other supermassive black holes. That's roughly 168 Jupiters across, and inside is the same amount of mass as 4 million suns combined. ![]() It covers a region about 14.6 million miles in diameter. But these black holes are nothing compared to supermassive black holes, like Sagittarius A*, which lives at the center of our Milky Way galaxy.
