A new study of the meteorite Erg Chech 002 makes it one of the most precisely dated space objects and changes our understanding of how elements were spread around the cloud of dust that formed the Sun and planets.
A mysterious hunk of space junk buzzed through Australian skies last night. It may have been the third stage of a Soyuz 2 rocket just launched by Russia.
Barely a week goes by without headlines about a giant asteroid coming past Earth. Here’s what really makes an asteroid pass notable – it’s not just size.
Temperatures plummeted across southeast Australia this week, with Canberra experiencing its lowest temperature since 2018 and the lowest for June since 1986. What’s going on?

An unusual folded shape in a meteorite prompted scientists to dive deep into a rabbit hole – discovering a potential new way to make specially shaped diamonds in the lab.
The green glow of an aurora is caused by oxygen ions in the upper atmosphere. Some meteors can glow in this way, too, but only if they are extremely fast.
Earth is moving through a bit of space where three streams of debris intersect with our orbit. These streams will give birth to the stars of this weekend’s show.
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.
This image shows meteors that skimmed the atmosphere during just one night in March this year.
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.
