Asteroids known as ‘S-type’ contain a lot more water than we thought.
New research demonstrates that the solar system is wetter than we thought.
Bruce Willis saved the Earth with a nuclear weapon in the 1998 film Armageddon, but the law would need to change for him to do it now.
Meteorites might look like boring bits of rock – but each one has a fascinating story.
How close can a potentially dangerous asteroid get before it’s detected?
We're finding more near-Earth objects all the time, and the challenge is to identify those that could potentially hit us. So how come we missed one that caused a huge blast in December?
An artist’s impression of an asteroid about to hit Earth: it’s what happens next that could have helped wipe out the dinosaurs 66 million years ago.
More evidence that the asteroid hit on Earth that marked the end of the dinosaurs could have triggered a deadly increase in volcanic activity.
The 2018 Geminids meteor shower recorded over two very cold hours on the slope of Mount Lütispitz, Switzerland.
Moonlight will spoil some of the big meteor showers this year, but still plenty of others to see. So here's your guide on when and where to look to catch nature's fireworks.
A spectacular display.
Expect a spectacular display of 120 or more meteors per hour – some of them brightly coloured.

Nearly 50 years since the first man walked on the moon, our morals are still stranded on Earth.
From moon landing to space arms race.
Trunp's new policy could lead to the militarisation of outer space and the beginning of a new space arms race.
