The Eta Aquariid meteor shower is set to light up the skies. Here’s how to get the best seat in the house

Each year, the Earth runs through a broad river of dust surrounding Comet Halley – giving birth to the spectacular Eta Aquariid meteor shower.

Mapping out meteorites in Antarctica: scientists’ bid to uncover our solar system’s deep past

Scientists have crafted the world’s first “treasure map” to reveal Antarctica’s meteorites. These chunks of stone-like material could throw light on the mysteries of our early solar system.

Curious Kids: Why are there so few impact craters on Earth?

Impact craters are relatively shallow, so these bowl-shaped “dents” in Earth’s rocky crust can be easily buried or erased by erosion.

Asteroid 2018 VP₁ may be heading for Earth. But there’s no need to worry

A small asteroid will cross Earth’s orbit on November 2. Scientists aren’t sure if the two will collide – but even if they do, there’s still no cause for alarm.

Meteorites from Mars contain clues about the red planet’s geology

Martian meteorites allow scientists here on Earth to decode that planet’s geology, more than a decade before the first missions are scheduled to bring rocks back home from Mars.

Tomanowos, the meteorite that survived mega-floods and human folly

Tomanowos, aka the Willamette Meteorite, may be the world’s most interesting rock. Its story includes catastrophic ice age floods, theft of Native American cultural heritage and plenty of human folly.
Much of Mars’s surface is covered by fine-grained materials that hide the bedrock. The above bedrock is mostly exposed and it is in these areas that micrometeorites likely to accumulate. NASA/JPL-Caltech/Univ. of Arizona

Tiny specks in space could be the key to finding martian life

It’s established Mars was once a planet with surface-level water. So with multiple MARS missions starting next year, the key to seeking out martian life may instead lie in the contents of its ‘dust’.
Near-Earth asteroids such as Bennu, and 2019 OK which passed close to Earth this week, pose a potential threat to our planet. NASA

An asteroid just buzzed past Earth, and we barely noticed in time

A 100-metre-wide asteroid passed just 70,000km from Earth on Thursday, and we had little warning it was about to happen. What threat is posed by asteroids and how do we find them?
