A 100-metre-wide asteroid passed just 70,000km from Earth on Thursday, and we had little warning it was about to happen. What threat is posed by asteroids and how do we find them?
Asteroids have played a key role in our history and will continue to do so in the future.
Every day about 50 tons of rocks from space fall on Earth. An examination of these meteorites has inspired a new theory about how exactly these rocks formed.
The origin of Libyan desert glass found scattered in an Egyptian desert has puzzled scientists for years. But a new look at the glass structure reveals its meteoric formation.
New research demonstrates that the solar system is wetter than we thought.
The source of water on Earth, the Moon and planets in our solar system is hotly debated. Some in the planetary science community argued that it came from asteroids and comets. Now they have proof.
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.
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?
More evidence that the asteroid hit on Earth that marked the end of the dinosaurs could have triggered a deadly increase in volcanic activity.
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.
Expect a spectacular display of 120 or more meteors per hour – some of them brightly coloured.
Osiris-REx will spend the next year looking for a good place to land on asteroid Bennu before it collects grains and brings them home.
Meteorite impacts have fundamentally shaped the history of our planet.
Senegal has made great strides in astronomy and planetary sciences in recent years.
Space mining has the potential to provide a greater supply of resources either for being exploited locally for construction or being sent back to earth.
Each meteorite is a piece of the puzzle to understanding our solar system.
We have long wondered why Earth has stayed habitable enough for life to evolve over billions of years.
A world expert weighs in on the continuing debate about ‘Oumuamua.
