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.

A new discovery of gravitational waves has black holes in a spin

Scientists have made a third detection of gravitational waves, again caused by the merger of two black holes. But they think there's something different about the black holes in this case.

Black holes are even stranger than you can imagine

The discovery of a new black hole adds to our understanding of these celestial objects that fascinate in both fact and fiction.

Second detection heralds the era of gravitational wave astronomy

The observation of gravitational waves from a second black hole merger implies there are many more black holes in the universe than scientists had previously anticipated.

Twisted light could dramatically boost internet speeds

The design of a new chip to detect the twisted nature of light waves could pave the way for next generation of optical communication technologies.

Supermassive black holes could be a source of mysterious cosmic rays

A new study suggests that mysterious high energy cosmic rays might originate from the supermassive black hole at the centre of our galaxy.
