Researchers have watched a huge crater form on the lunar surface, and its widespread effects could help inform future exploration of the moon and other similar places

Stunning pictures of nebulae, stars, the moon and more took top prizes in this year's astrophotography competition, organised by the Royal Observatory in London

We may have finally spotted a dark matter particle – but figuring out exactly what kind of particle it was is a daunting task.

Physicists have long struggled with their goal of making gravity a quantum force. A radical post-quantum approach might solve that problem – and clear up other cosmic mysteries, too

Near the centre of the Milky Way, a swarm of stars hurtles around a supermassive black hole at extraordinary speeds. Studying them could be the key to understanding our galaxy

The Roman telescope is NASA’s newest space observatory. Every 10 months, it will get the equivalent of about 1000 years' worth of Hubble observations. Will it find the answers to our questions about dark matter and dark energy?

OpenAI has released hundreds of papers claiming to make progress on the biggest open problems in mathematics – here are some with the most potential

The Martian Moons eXploration spacecraft, set to launch on 20 October, will bring back samples that should solve a moon mystery that has been vexing scientists for more than a century
