The discovery raises big questions about widely accepted models of galaxy formation.

It’s too heavy to be a neutron star and too light to be a black hole. So what is it?

Pictures of black holes have a white outline around them when photographed, due to one of black holes’ unique and key features.

An astronomer and ‘black hole historian’ explains how the parts of the universe black holes grow in might influence how quickly they become bright, supermassive objects.

Astronomers have for the first time detected the background hum of gravitational waves likely caused by merging black holes.

New data from the IceCube collaboration shows neutrino emissions from within our Milky Way galaxy – but figuring out where exactly these ghost particles come from is harder than it seems.

Radiation from the brightest cosmic explosion ever seen may have been mixing with gas and dust around its dying star – making the signal last longer.

Upgrades to the hardware and software of the advanced observatory should allow astrophysicists to detect much fainter gravitational waves than before.

Artificial intelligence tools are making waves in almost every aspect of life, and astronomy is no different. An astronomer explains the history and future of AI in understanding the universe.
