Zapping away space junk
Planet Earth is surrounded. Thousands of tons of dangerous space debris circle in low orbit, threatening serious damage, even death, if any were to strike the International Space Station. A proposal by a ...
Meteorites key to the story of Earth's layers
A new analysis of the chemical make-up of meteorites has helped scientists work out when the Earth formed its layers.
Fierce 'superflares' from the sun zapped an infant Earth
Our young sun may have routinely blasted Earth with gobs of energy more powerful than any similar bombardments recorded in human history.
Snowball Earth: New study shows Antarctic climate even gripped the tropics
New details of a nightmare period on Earth with surface conditions as frigid as present-day central Antarctica at the equator have been revealed thanks to the publication of a study of ancient glacier water.
A timeline of comet probe's 11-year journey
The European Space Agency said Sunday that its comet lander Philae has woken up from hibernation and managed to send data back to Earth for the first time in seven months. The probe went quiet on Nov. 15, thr ...
A new level of earthquake understanding
As everyone who lives in the San Francisco Bay Area knows, the Earth moves under our feet. But what about the stresses that cause earthquakes? How much is known about them? Until now, our understanding of ...
Europe set for launch of "space plane" prototype
Engineers were preparing for the launch Wednesday of a "space plane" that Europe hopes will help it master a key phase in orbital flight—the ability to return to Earth.
Finding fault: New information may help understand earthquakes
New modeling and analyses of fault geometry in the Earth's crust by geoscientist Michele Cooke and colleagues at the University of Massachusetts Amherst are advancing knowledge about fault development in ...
Ascent or no ascent? How hot material is stopped in the Earth's mantle
The largest magmatic events on Earth are caused by massive melting of ascending large volumes of hot material from the Earth's interior.
The origins and future of Lake Eyre and the Murray-Darling Basin
Geoscientists have, for the first time, discovered the origins of Australia's two largest basins: Lake Eyre and the Murray-Darling Basin. The research also implies that in 30 million years' time both basins ...
How long does it take to get to Pluto?
It's a long way out to the dwarf planet Pluto. So, just how fast could we get there?
Same forces as today caused climate changes 1.4 billion years ago
