Giant meteorite impacts may have created the land we live on
By tracking a meteorite found in Morocco back to its origin in an asteroid crater on Mars millions of years ago, scientists can learn more about how the planets formed.
When the meteor exploded into pieces above New Zealand, it produced a shock wave strong enough to be picked up by earthquake seismometers. But any fragments have likely dropped into the ocean.
Current trends suggest that powerful nations are defining the rules of resource use in space and satellite access in ways that will make it hard for developing nations to ever catch up.
A recent BBC documentary examined fossils thought to have been made when an asteroid wiped out the dinosaurs.
NASA has only mapped 40% of the potentially dangerous asteroids that could crash into Earth. New projects will boost that number, and upcoming missions will test tech that could prevent collisions.
The Hayabusa2 mission brought a piece of asteroid Ryugu back to Earth, where it has helped scientists resolve a long-standing puzzle.
There may be many more asteroids in the same orbit as Earth, some of which we might be able to mine.
There’s no need to panic about the asteroids heading ‘close’ to Earth in January.
Nasa plans to test its new rocket system for the Moon, and a new rover is due to begin its journey to Mars.
Experts give us a science preview for 2022, plus what lies in store for global inequality. Listen to The Conversation Weekly podcast.
We may be on the brink of discovering whether water and organic material, which enabled life on Earth, came from asteroids.
Tiny pieces of an asteroid have revealed an unlikely origin for much of the water in Earth’s oceans.
An asteroid that landed in Russia in 2013 injured 1,500 people – and was just 20 metres in diameter. What could we do if a major threat was detected?
The Lucy mission could revolutionise our knowledge of the Solar System’s history, while the DART mission could help redirect hazardous asteroids in the future.
New research suggests that fire from the sky in the form of a small asteroid annihilated a city near the Dead Sea 3,600 years ago.
If the asteroid caused the very sudden end of the dinosaurs, a new study shows that their decline had begun 10 million years earlier.
You might think lots of meteorites ultimately come from comets. Turns out, you’d be wrong, according to a new study that tracked meteors hurtling through the sky to find out where they came from.
A minuscule particle of asteroid dust has helped reveal how celestial rocks like Earth might have sprouted life.
There’s a good reason why so many scientists disagree with claims that Earth has been visited by aliens.
