Scientists cast doubt on theory of what triggered Antarctic glaciation
A team of U.S. and U.K. scientists has found geologic evidence that casts doubt on one of the conventional explanations for how Antarctica's ice sheet began forming. Ian Dalziel, research professor at The ...
NASA's next Mars rover will advance hunt for past life
The next robotic rover to explore Mars in 2020 should scour the surface of the red planet more closely than ever for signs of past life, a NASA science team said Tuesday.
New study suggests Earth's lower mantle penetrated by metallic blobs
Melvin Calvin's moon dust rediscovered at Berkeley Lab
(Phys.org) —When Apollo 11 returned from its historic flight in 1969, the moon rocks and lunar soil collected by Neil Armstrong and Buzz Aldrin eventually found their way to some 150 laboratories worldwide. ...
Scientists find Moon, asteroids share history

Lunar impacts created seas of molten rock, research shows
Early in the Moon's history an ocean of molten rock covered its entire surface. As that lunar magma ocean cooled over millions of years, it differentiated to form the Moon's crust and mantle. But according ...
Curiosity rover: No big surprise in first soil test
(Phys.org)—NASA's Mars Curiosity rover has used its full array of instruments to analyze Martian soil for the first time, and found a complex chemistry within the Martian soil. Water and sulfur and chlorine-containing ...
Improved simulation methods help scientists bolster theories of Moon's formation
(Phys.org)—There are still unanswered questions regarding how the Moon was formed. Improved simulation methods and higher-performance supercomputers have now paved the way for an alternative development ...
Oceanic islands preferred thin crust
