Gravitational waves may have provided the first tantalizing evidence of tiny primordial black holes born during the Big Bang, ...

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

It may sound like science fiction, but imagining a battle between a gas giant and a black hole helps us understand just how fragile our Solar System really is. Such a scenario might seem impossible, ...

Last year, astronomers were fascinated by a runaway asteroid passing through our solar system from somewhere far beyond. It was moving at around 68 kilometres per second, just over double Earth's ...

Black holes are among the most extreme objects in the universe, and now scientists can model them more accurately than ever before. By combining Einstein’s gravity with realistic behavior of light and ...

In a patch of sky about 1.2 billion light-years from Earth, astronomers have found a cosmic rarity: three galaxies caught in a merger, and all three of their central supermassive black holes are ...

Astronomers may have uncovered the origins of the mysterious “little red dots,” some of the strangest galaxies seen in the early universe. These tiny but brilliant objects, discovered by the James ...

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 new simulation could help solve one of astronomy’s longstanding mysteries—how supermassive black holes formed so rapidly—along with a new one: What are the James Webb Space Telescope’s (JWST) ...

Last year, astronomers were fascinated by a runaway asteroid passing through our Solar System from somewhere far beyond. It was moving at around 68 kilometres per second, just over double Earth’s ...
