World's third largest asteroid impact zone found in South Australia
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.
A crater as an abode for life
A new study shows how the heat generated from an asteroid impact could lead to a crater becoming a refuge for life, or even a potential birthplace for life's origin.
Man in the Moon has 'Graphite Whiskers'
Up to now scientists thought that the trace amounts of carbon on the surface of the Moon came from the solar wind. Now researchers at the Carnegie Institution's Geophysical Laboratory have detected and dated ...
Charitum Montes: A cratered winter wonderland
(Phys.org)—The high-resolution stereo camera on ESA's Mars Express imaged the Charitum Montes region of the Red Planet on 18 June, near to Gale crater and the Argyre basin featured in our October and November ...
Crater discovery's impact echoes still today
Desmond Moser never gives up. Twenty years ago, the now Western Earth Sciences professor first visited the heart of South Africa's Vredefort impact crater, locating what he believed to be some of the only ...
Rocky mounds and a plateau on Mars

Volcanic ash in Meridiani Planum
Deposits of volcanic ash colour this view of the Meridiani Planum, as seen by the Mars Express High Resolution Stereo Camera. They also give clues to the prevailing wind direction in this region of Mars.
Meteorite shockwaves trigger dust avalanches on Mars
(PhysOrg.com) -- Dust avalanches around impact craters on Mars appear to be the result of the shock wave preceding the actual impact, according to a study led by an undergraduate student at the UA.
Impact craters may have been cradles of life
(Phys.org)—Even comparatively small meteorite impact craters may have played a key role in the origin and evolution of early life on Earth, according to a researcher at The University of Western Australia.
Explosive crater twins on Mars
(Phys.org) —Dramatic underground explosions, perhaps involving ice, are responsible for the pits inside these two large martian impact craters, imaged by ESA's Mars Express on 4 January.
Cascading dunes in a Martian crater
A new mosaic from ESA's Mars Express shows a swirling field of dark dunes cascading into sunken pits within a large impact crater.
Impacts could be boon for subterranean life
An incoming asteroid is trouble whether you're a dinosaur or a Bruce Willis fan. But microbes living deep underground may actually welcome the news, according to a recent study of an ancient impact in the ...
