No conclusive evidence that extraterrestrial life exists has been found...yet.
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.
The hunt for the space rock involved a few bits of sheep poo before the real meteorite was found.
It looks like a broken barbeque brickette, but the newfound meteorite is a capsule of the Solar System’s history that could reveal the secrets of the origin of life.
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.
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, 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.
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’.
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?
Asteroids have played a key role in our history and will continue to do so in the future.
Every day about 50 tons of rocks from space fall on Earth. An examination of these meteorites has inspired a new theory about how exactly these rocks formed.
Security cameras captured two separate fireballs over Australia this week. So what’s responsible these bright flashes?
The source of water on Earth, the Moon and planets in our solar system is hotly debated. Some in the planetary science community argued that it came from asteroids and comets. Now they have proof.
If you’ve never heard of a form of wave called a ‘seiche’ – which can occur in swimming pools during earthquakes – this is your chance to catch up.
We’re finding more near-Earth objects all the time, and the challenge is to identify those that could potentially hit us. So how come we missed one that caused a huge blast in December?
The comet 46P/Wirtanen is just 1.2km in size but it should be visible in the night sky this Saturday as it makes a close approach to Earth this year. And don’t forget the Geminids meteor shower.
Expect a spectacular display of 120 or more meteors per hour – some of them brightly coloured.
Meteorite impacts have fundamentally shaped the history of our planet.
A meteorite hitting Earth at many kilometres per second puts ‘ground zero’ target rocks under immense pressure. A shock wave faster than the speed of sound can result – and new materials created.
Space mining has the potential to provide a greater supply of resources either for being exploited locally for construction or being sent back to earth.
