An award with real gravity: how gravitational waves attracted a Nobel Prize

The 2017 Nobel Prize for Physics was awarded to scientists who helped pioneer the discovery of gravitational waves. Australia is playing an important role in gravitational-wave astronomy.

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.

2016: the year in space and astronomy

Colliding black holes to exploding spacecraft, 2016 was an incredible year for astrophysics.

2016, the year that was: Science + Technology

From the discovery of gravitational waves, to the Pokémon Go phenomenon to the Census debacle, it's been a big year in science and technology.

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.

Explainer: making waves in science

We find them at the beach, in every sound and light show, the miracle of wi-fi and now in the fabric of space-time itself. But what exactly is a wave?
