At last, we’ve found gravitational waves from a collapsing pair of neutron stars

Astronomers have finally confirmed the source of the latest detected gravitational waves was the collission of a pair of neutron stars, what they'd been searching for all along.

Where are the missing gravitational waves?

A new study has failed to find evidence of gravitational waves, but that doesn't mean Einstein was wrong about their existence.

Explainer: what is a neutron star?

They're are the overachievers of the universe: incredibly dense but very small when compared to others stars. So how much do we know about the extreme behaviour of neutron stars?

A rare magnetic star is born – with a push in the right direction

Magnetars are stars that are incredibly dense, rapidly spinning, amazingly hot and – as their name suggests – are the most magnetic objects known in the universe. The magnetic field on the surface of a…
