Some things in cosmology may simply be unknowable. Why is there something rather than nothing? What lies outside the universe? What is inside a black hole? That last one has been niggling at ...
A fresh black hole merger detection has offered the clearest evidence yet for Einstein’s relativity and Hawking’s predictions. Scientists tracked the complete cosmic collision, confirming that black ...
In a significant potential shift for astrophysics, it turns out that some quasars may weigh as little as half what was previously believed. Share on Facebook (opens in a new window) Share on X (opens ...
Some of the mysterious pinpricks of light at the dawn of the Universe could be a type of object we've never seen before. According to a new analysis of a "little red dot" (LRD) nicknamed The Cliff, ...
Listen to more stories on the Noa app. To study the origins of our universe is to struggle with profound chicken-or-egg questions. We know the Big Bang happened. Cosmologists can see its afterglow in ...
At the heart of nearly every galaxy lurks a cosmic giant: a supermassive black hole. These mysterious objects, millions to billions of times more massive than our Sun, exert such powerful gravity that ...
In a recent piece for my column The Universe, I wrote about the biggest black holes in the cosmos. These can tip the scales at many billions of times the sun’s mass, outweighing even entire galaxies.
New observations of M87*, the first black hole ever imaged, revealed that the supermassive blackhole has experienced several magnetic flips in the last decade. reading time 3 minutes In 2019, ...
In this handout photo provided by the National Science Foundation, the Event Horizon Telescope captures a black hole at the center of galaxy M87 in an image released on April 10, 2019. (Photo by ...
A black hole unlike any seen before has been spotted in the early universe. It’s huge and appears to be essentially on its own, with few stars circling it. The object, which may represent a whole new ...
Back in 1971, the late physicist Stephen Hawking made an intriguing prediction: The total surface area of a black hole cannot decrease, only increase or remain stable. So if two black holes combine, ...
Physicists may soon witness a cosmic fireworks show: the explosive death of a primordial black hole. Once thought to be unimaginably rare, new research suggests there’s up to a 90% chance of catching ...
