Ten years ago, on 14 September 2015, a new window on the Universe was opened, giving us a novel way of studying exotic, high-energy objects such as black holes and neutron stars: the first direct dete

An astrophysicist has made a daring proposal to send ...

Get sucked into an astronomical mystery as we get in a spin with the universe’s heaviest objects.

Astronomers love a challenge. They place their observatories on the highest mountains, in the driest deserts, on the coldest ice shelves, beneath the deepest oceans, in orbit around Earth and the Sun,

What is normal or ‘ordinary’ matter? When astronomers talk about normal matter, we’re referring to baryons. By that, we just mean ‘the stuff of atoms’ – things like protons and neutrons. How did we fi
