The largest meteorite impact site in the world may be right here in central Australia.
Clear skies this Australia Day could give observers a rare look at a giant asteroid flying past Earth at 56,000kmh. The asteroid, known as 2004 BL86, will not return to Earth for around another 200 years…
The European Space Agency’s Rosetta mission to land on comet 67P was one of the most audacious in space history. The idea of landing on a small chunk of icy rock 300m kilometres away from Earth and hurtling…
The best meteor shower of the year should put on an impressive display this weekend – weather permitting – with the annual Geminids poised to light up the sky with bright, long meteors visible as frequently…
The golden age of planetary exploration had voyagers navigating new sea routes to uncharted territory. These territories were then claimed in the name of the monarchs who had financed the expeditions…
Millions of asteroids of all shapes and sizes are littered throughout the inner solar system. In the past three decades, scientists have spotted as many as 500,000 but many more remain unseen. Many of…
Earth was still a violent place shortly after life began, with regular impactors arriving from space. For the first time, scientists have modelled the effects of one such violent event – the strike of…
In a surprise discovery two rings have been found around the remote asteroid Chariklo, which lies more than a billion kilometres from Earth. This is the first time rings have been discovered around an…
Comet ISON’s fate has left many sad. For the public, the comet could have made for a spectacular view in December. For scientists, it would have been a chance to learn more about these mysterious bodies…
When you clean your house you are probably vacuuming up space dust. Not kidding. It is the same dust that was once part of comets and asteroids. You see that dust in the faint glow it helps create before…
Three studies have revealed details of the meteor that exploded above Russian city, Chelyabinsk, in February this year. Their findings, published today in a pair of papers in Nature and one in Science…
How will future alien scientists know whether life existed in our solar system? One method may be to sift through the planetary debris left when our sun becomes a white dwarf. Astronomers are doing just…
One of the most exciting things about science is the detective work, and never was this more the case than Friday. Within an hour or so of the event, almost everyone had seen the dramatic footage of the…
A fireball has flown over Russia, delivering a sonic boom with enough force to shatter windows, amateur footage shows. The astronomical event comes just one day before a large asteroid is expected to pass…
An asteroid measuring up to 20km across hit South Australia up to 360 million years ago and left behind the one of the largest asteroid impact zones on Earth, according to new research published today…
An asteroid named 2012 DA14 will come within 27,700 kilometres of Earth early on Saturday morning Australian time (around 6:30am AEDT). At this distance the asteroid will pass within the orbits of several…
An asteroid expected to hurtle past Earth next week will fly within range of communication satellites but will not hit the planet, experts said today. Known as 2012 DA14, the asteroid is around 45m in…
The prospect of people settling away from Earth has been a topic for dreamers and visionaries for some time. But if it’s ever to happen for real, there needs to be more than starry-eyed optimism. There…
The presence, size and location of an asteroid belt may determine if life can evolve on an Earth-like planet. If this is…
