It all depends on how much mass is inside. So there you have it, black holes can be millions of times larger than suns and planets or as small as a city. And it's estimated to be about 21 billion times the mass of our sun. For perspective, that's about 40% the size of our solar system, according to some estimates. It has a diameter of about 78 billion miles. The work suggests that at least ten of the galaxies contain an ultramassive. This analysis has looked at the brightest galaxies in a sample of 18 galaxy clusters, to target the largest black holes. So we have to look at one of the most massive of all supermassive black holes. Typically, these black holes, located at the centers of galaxies, have masses ranging between a few million and a few billion times that of our sun. But this supermassive black hole, as large as it is, could still fit within our solar system with plenty of room to spare. 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. So let's look at the supermassive black hole at the center of the Sombrero galaxy. 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. It's nearly twice the size of Jupiter, spanning a region about 172,000 miles wide, but inside is as much mass as 47,000 suns.īut these black holes are nothing compared to supermassive black holes, like Sagittarius A*, which lives at the center of our Milky Way galaxy. At 1,460 miles across, it's nearly large enough to stretch from Florida to Maine and, according to some calculations, contains the mass of 400 suns.Īt this point, black holes start to get pretty big compared to Earth, but it's still nothing when you consider the sheer mass they carry. Up next are the intermediate-mass black holes, like this one. In another galaxy, called M33, there's a black hole that is 58 miles across and packs as much mass as 15.7 suns inside. But in that small space is enough mass to equal 11 of our suns. The smallest are stellar black holes, which form after a giant star explodes and collapses in on itself, like this one, which measures about 40 miles across, roughly three times the length of Manhattan. There are three common types of black holes. Here's just how big black holes can really get. To make Earth into a black hole, for instance, you'd have to shrink it to less than an inch across.īut real black holes are much larger than that and pack way more mass than Earth. You see, the more mass you can shrink into a small space, the stronger your gravitational force will become. They're some of the most violent objects in our universe, powerful enough to rip entire stars to pieces. Narrator: The cosmos can be a dangerous place.
Talking about the latest discovery, lead author Dr James Nightingale, of the Department of Physics at Durham University, said: "This particular black hole, which is roughly 30 billion times the mass of our Sun, is one of the biggest ever detected and on the upper limit of how large we believe black holes can theoretically become, so it is an extremely exciting discovery.Account icon An icon in the shape of a person's head and shoulders. This comes days after an international team of experts found that a supermassive black hole at the centre of a galaxy named PBC J2333.9-2343 has changed direction and is now aiming towards the Earth.Īstronomers believe that such massive black holes can be found at the centre of all large galaxies such as the Milky Way, which includes our own solar system. The news about its discovery has been published in the journal Monthly Notices of the Royal Astronomical Society, and has been dubbed "extremely exciting", according to the outlet. Metro quoted the scientists from Durham University as saying that this is one of the biggest ever black hole found. Space scientists in the UK have discovered a supermassive black hole 33 billion times the mass of Sun.
