WASHINGTON >> Scientists are observing the most energetic flare ever seen emanating from a supermassive black hole, apparently caused when this celestial beast shredded and swallowed a huge star that strayed too close.
Cosmic inflation helps black holes grow quickly, but it can't explain how supermassive black holes grew to billions of solar masses in less than 500 million years.
A supermassive black hole gobbled up a huge enormous star, producing the biggest and most distant black hole flare ever recorded, according to a new study.
A black hole far from its galactic center has unleashed the fastest, brightest radio flares ever seen from a star’s destruction. For the first time, astronomers have detected a tidal disruption event (TDE), when a black hole destroys a…
For the first time, scientists observed a black hole tearing apart a star far from its galaxy’s center, producing the fastest-changing radio signals ever recorded. The event, AT 2024tvd, revealed delayed bursts of energy months after the…
When two galaxies merge, the supermassive black holes at their centres should eventually find each other and begin a gravitational dance that lasts millions of years. Despite decades of predictions, astronomers are still hunting for…
For the first time, astronomers have produced a radio image revealing two black holes orbiting each other, confirming long-suspected black hole pairs. The system sits at the core of quasar OJ287, where a supermassive black hole powers an…
