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.
A recent study shows that the Earth’s water could come directly from the oxygen and hydrogen present in the rocks that formed it, and not from a late supply by asteroids.
A poor start for meteor showers in 2021 but things get better with a possible spectacular surprise later in the year. Here’s your guide on when and where to look to catch nature’s fireworks.
If the building blocks of life were present at the time that Earth was born, this could mean life is common in the universe.
