Massive bodies can send ripples through space time in the form of gravitational waves. NASA

Gravitational waves discovered: top scientists respond

The long awaited discovery of gravitational waves has sent ripples through the scientific world. Here top experts respond to the historic announcement.

Gravitational waves discovered: the universe has spoken

The detection of gravitational waves is the final confirmation of Einstein's theory of general relativity, and opens up a new window into the cosmos.

Tuning in to cosmic radio from the dawn of time

The Murchison Widefield Array sits in remote Western Australia far from noisy civilisation so it can help us understand the universe by tuning into radio waves from the distant cosmos.
Can a galaxy (like NGC 3810 in this case) have a classical spiral structure and also be already dead? ESA/Hubble and NASA

Is our Milky Way galaxy a zombie, already dead and we don’t know it?

Extragalactic astrophysicists want to know how and why galaxies stop forming stars, change their shape and fade away. With help from citizen scientists, they're figuring it out.

How neutrinos, which barely exist, just ran off with another Nobel Prize

They're beyond tiny and super mysterious. Neutrinos are an elemental particle that might just help us understand the structure and evolution of the universe.

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.

Indigenous culture and astrophysics: a path to reconciliation

The night sky is part of the shared heritage of all people on Earth. A project to bring Indigenous Australians and astrophysics together reveals our common wonder at the mysteries of the universe.
