A tiny particle that smashed into Earth with a record-shattering energy of 220 petaelectronvolts could be the last scream of an evaporating black hole. According to a new theoretical paper, the 2023 ...

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 ...

An international team led by Monash University has uncovered evidence of a rare form of exploding star, helping to shed light ...

In 2023, a subatomic particle called a neutrino crashed into Earth with such a high amount of energy that it should have been impossible. In fact, there are no known sources anywhere in the universe ...

On Wednesday, researchers released an analysis suggesting that there’s a “mass gap” in the population of black holes that ...

Stellar black holes form from the collapse of massive stars at the end of their lives, typically weighing 3 to 50 times the mass of the sun. When a star runs out of fuel, it explodes in a supernova, ...
