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
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
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 uncovered more than 400 previously hidden black holes feeding on stars and dust in the center of galaxies. It appears that many of the new black holes, discovered using NASA’s Chandra X-ray Observatory, remained unknown until now because they are buried beneath cocoons of dust. Supermassive black holes, which can be millions of … Read more
Black holes are scary beasts — objects so massive that not even light can escape their clutches. In 2022, we learned more about these gravitational monsters than ever before — from the first direct image of the black hole “heart” at the center of the Milky Way to one of the earliest black hole ancestors … Read more
Black holes are some of the most enigmatic objects in the universe. This is partially because the equations of general relativity that we use to understand them break down when studying black holes’ ultra-dense centers. However, a new paper shows how astronomers could one day overcome this challenge by using gravitational waves to “see” inside … Read more
Researchers studying the aftermath of a gargantuan black hole collision may have confirmed a gravitational phenomenon predicted by Albert Einstein a century ago. According to new research published today (Oct. 12) in the journal Nature (opens in new tab), the phenomenon — which is known as precession and is similar to the wobbling motion sometimes … Read more
Black holes are cosmic vacuum cleaners — massive objects so large that not even light can escape them. Most people imagine black holes do nothing but sit there and devour wandering pieces of gas or dust. But could black holes actually have more interesting interior lives? Could they, for instance, explode? If an “explosion” is … Read more
Space: the final frontier. The region between our home planet and everything else in the universe is a big unknown — full of untold wonders, celestial objects so big they boggle the mind, and some truly catastrophic events. Here are seven of the most terrifying things in space. Are you ready for a “megacomet”? The … Read more
A seemingly intractable black hole paradox first proposed by physicist Stephen Hawking could finally be resolved — by wormholes through space-time. The “black hole information paradox” refers to the fact that information cannot be destroyed in the universe, and yet when a black hole eventually evaporates, whatever information was gobbled up by this cosmic vacuum … Read more
