Black Hole

This artist’s impression illustrates the mechanism that could be at the origin of the powerful bursts of X-ray light seen from a newly awakened black hole named Ansky.

Although we know that supermassive black holes (millions of times the mass of our Sun) lurk at the centre of most galaxies, their very nature makes them difficult to spot and study. In contrast to the popular idea of black holes constantly 'gobbling up' matter, these gravitational monsters can spend…

Supermassive black holes are challenging to observe because they can stay dormant for long periods. This was the case for the black hole in galaxy SDSS1335+0728, 300 million light-years away in Virgo. After decades of inactivity, it suddenly became active, emitting powerful X-ray bursts. The galaxy SDSS1335+0728, which had remained…

Astronomers using the MUSE instrument at ESO’s Very Large Telescope (VLT) have detected supermassive black hole-driven winds in the barred spiral galaxy NGC 4945. This image shows NGC 4945, a spiral galaxy over 12 million light-years away in the constellation of Centaurus; NGC 4945’s supermassive black hole-driven wind is shown…

If Instagram has got you down as much as it has me down (I can’t even find friends’ photos anymore amid the deluge of AI-narrated spam posts and “suggested for you” nonsense), Fujifilm may have the antidote you needed. The company’s new Instax Mini 41 is a tightly-packed point-and-shoot instant…

Black Holes May Be ‘Supermazes’ of Many-Dimensional Strings Physicists think the insides of black holes may be complex mazes of tangled strings in higher dimensions By Clara Moskowitz edited by Jeanna Bryner Jose A. Bernat Bacete/Getty Images Black holes, the densest objects in the universe, eat up anything that comes…

Black holes are regions of space with gravity so strong that even light cannot escape. In general relativity, traditional black holes are surrounded by an event horizon. From an outside perspective, these black holes appear featureless—a contradiction to quantum mechanics, which suggests they must have intricate microstructure. String theory introduces…

One of the most powerful objects in the universe is a radio quasar — a spinning black hole spraying out highly energetic particles. Come too close to one, and you'd get sucked in by its gravitational pull, or burn up from the intense heat surrounding it. But ironically, studying black…
