A zap with a laser in the lab confirmed the extraterrestrial origins of enigmatic lumps of glass found in the Northern Territory.
The mission provided details about how to deflect an asteroid should one threaten Earth in future.
Moons and asteroids will be visited by spacecraft from Earth next year.
George Lucas named Luke Skywalker’s home planet after a Tunisian town and meteorite.
Libyan desert glass originated from the impact of a meteorite on the Earth’s surface.
In September 2023, a NASA mission successfully brought samples of an asteroid down to Earth in a sealed capsule. Analysis of these samples may reveal information about the origins of the universe.
Upcoming NASA missions will help scientists understand the composition of asteroids – which could inform companies one day hoping to commercially mine asteroids.
Scientists have been searching Earth’s surface for superheavy elements too difficult to make in the lab, but now, many are looking to the skies instead.
Some space rocks you can get for free – if you know how to identify them. Rarer materials cost more, and the asteroid sample NASA just brought back has a high price tag.
A distant lump of space rock may have a surprising amount in common with the core of our own planet.
Studying the sample could help answer how water arrived on Earth and how life started.
The asteroid is interesting from a scientific perspective as well as a commercial one.
Controlled experiments are impossible in astronomy, as are direct measurements of physical properties of objects outside our solar system. So how do astronomers know so much about them?
Meteorites are usually discovered by someone who notices an unusual rock while out walking.
NASA’s OSIRIS-REx mission has delivered pieces of asteroid Bennu, which scientists hope will offer a window into the early era of the Solar System billions of years ago.
Scientists have discovered a new species of mosasaur, a sea-dwelling lizard from the age of the dinosaurs, with strange, ridged teeth unlike those of any known reptile.
Missions to asteroids are opening up the secrets of the Solar System
