Battered by asteroid impacts, the young Earth was hot and unstable for hundreds of millions of years.
An observatory director describes the differences between the types of rocks that fly through space.
Astronomers will investigate this fireball to help disentangle the heritage and history of the Solar System’s formation.
A week after the asteroid impact, rotting vegetation, smoke and sulphur create a stinky planet. Plant and animal survivors succumb to the corrosive acid rain.
A newly identified meteor shower reveals that intense heat is fragmenting a previously unknown asteroid as it passes too close to the Sun.
Ingredients for life may have been widespread throughout the Solar System in its early years.
Understanding their make-up is vital if a large space rock ever heads our way.
The Rubin Observatory in Chile has the largest camera ever built – and is set to find objects never before seen by human eyes.
If you’re like most people, you’ve never heard of it. Meet the ringed asteroid-comet hybrid prowling the outer reaches of the Solar System.
The activities of illegal miners are a threat to the sustainability of the crater.
An object dubbed 3I/ATLAS is only the third interloper from outside the Solar System seen in all of human history.
Keeping Earth safe from asteroids isn’t just spotting them – it’s also helping people understand what a high-impact probability with Earth means.
The Vera C. Rubin Observatory will capture enough detail to see a golf ball from 25km away.
Palynologists who study tiny pollen fossils share 4 stories found in grains that fell hundreds to millions of years ago.
Missions that return asteroid samples bring home more than just very expensive dust. These samples can provide valuable insights for scientists and commercial interests.
The Earth started as a mixture of gas and dust around the Sun and grew as it collided with asteroids and dust particles.
Learning about these interstellar objects could give us insights into other star systems.
Water-rich meteorites contain key ingredients for life, yet they barely appear in meteorite collections. Recent research using shooting stars may explain why.
Asteroids’ orbits around the sun may put them in collision paths with inner planets. We may have had a near-miss, but asteroids can pass by the Earth undetected.
