Black holes are massive, mostly invisible and so powerful not even light can escape them. So what would happen if one entered our solar system? It depends on a lot of factors, including the size and distance of the black hole, experts told Live Science. But in many scenarios, not much would happen.”They’re not, per … Read more
The monster black hole at the center of our galaxy may be unleashing huge, gassy explosions — and now, astronomers think they’ve pinpointed the exact spot where that superheated gas is spilling into the Milky Way. Acting like a gargantuan exhaust vent, the newly discovered feature is a bright region of X-ray energy that’s nearly … Read more
Ever wondered what it would be like to fall into a black hole? A new NASA simulation has the answer — including the inevitable, crushing end. Researchers created the new simulation using the Discover supercomputer at the NASA Center for Climate Simulation. It shows a viewer plunging through the accretion disk of glowing gas around … Read more
Scientists have spotted the brightest and fastest-growing quasar ever seen — a monster black hole that’s devouring a sun’s-worth of material every day. The brightly burning object, named J0529-4351, weighs between 17 billion and 19 billion solar masses and is located 12 billion light-years from Earth — meaning it dates to a time when the … Read more
Some of the universe’s oldest black holes swoop past our cosmic neighborhood at least once every decade, moving planets in their wake, a new study suggests. And if scientists can detect them, it would provide the first proof that these black holes exist as dark matter. Black holes, regions of immense gravity that even trap … Read more
Astronomers have discovered hundreds of strange, stringlike structures at the center of our galaxy, possibly tracing the violent path of an ancient black hole eruption. According to new research published June 2 in The Astrophysical Journal Letters, each of these previously unknown “filaments” measures between 5 and 10 light-years in length — thousands of times … Read more
Stephen Hawking’s most famous theory about black holes has just been given a sinister update — one that proclaims that everything in the universe is doomed to evaporate. In 1974, Hawking proposed that black holes eventually evaporate by losing what’s now known as Hawking radiation — a gradual draining of energy in the form of … Read more
Astronomers have discovered one of the largest black holes ever found — an ultramassive monster roughly 30 billion times the mass of the sun — using a space-time trick predicted by Albert Einstein. The colossal black hole, which lurks 2.7 billion light-years from Earth in the brightest galaxy of the galaxy cluster Abell 1201, was … Read more
Glimpsed only occasionally at the hearts of massive clusters of galaxies, ultramassive black holes are some of the largest and most elusive objects in the universe. These black hole behemoths have masses exceeding that of 10 billion suns, making them far more monstrous than even the supermassive black holes found at the centers of galaxies … Read more
Astronomers have spotted a runaway supermassive black hole, seemingly ejected from its home galaxy and racing through space with a chain of stars trailing in its wake. According to the team’s research, which was published April 6 in The Astrophysical Journal Letters (opens in new tab), the discovery offers the first observational evidence that supermassive … Read more
