Black Hole

For more than 30 years, astronomers have been observing and studying the elliptical galaxy NGC 4486B . But further observations revealed a supermassive black hole with a mass of about 360 million times that of the Sun, located in an unusual region. Indeed, in most galaxies, supermassive black holes are…

Supermassive black holes are believed to be at the heart of every galaxy, but how did they get so big? Likely by gobbling up other black holes, astronomers say.  Unfortunately, supermassive black holes in close proximity to each other have proved difficult to find—until now. New research from the Max…

(Image credit: Robert Lea (created with Canva)) Ripples in the very fabric of space and time called "gravitational waves" may have provided the first tantalizing evidence of tiny black holes born during the Big…

Astronomers have spotted an intriguing triple-galaxy system, nicknamed "The Stingray," that dates to when the universe was just over 1.1 billion years old. A new analysis of the celestial sea creature has revealed an object that may provide clues about the nature of mysterious cosmic objects dubbed "little red dots"…

Astronomers studying the galaxy Mrk 501 have identified a second jet of matter near its core, an unexpected feature in a system thought to host a single supermassive black hole. The discovery comes from more than two decades of high-resolution radio observations, collected across dozens of sessions and multiple frequencies…

Supermassive black holes literally don’t add up. Astrophysicists know it takes more time than is mathematically possible for one…

In 2023, scientists detected a subatomic particle called a neutrino hitting Earth with an energy level so extreme it seemed impossible. No known cosmic process can generate that much energy. The particle carried about 100,000 times more energy than anything ever produced by the Large Hadron Collider, the most powerful…

Mary Wansey has spent 19 bleak months stranded in a Canberra hospital room while she waits for a place in aged care. "We've fallen into a black hole," she said. "It just seems it doesn't matter what we do or where we apply." In August 2024, while she was living…

Skip to content LIGO data hints at supernovae so powerful they leave nothing behind Pair instability supernovae create a “mass gap” in black holes. Many of the early exoplanet discoveries were exciting on their own, confirming that there really were strange new worlds out in the Universe. But over time,…
