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.
Researchers claim reexamination of rock samples confirms meteoritic origin of Tunguska cosmic body
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. ...
Geologic study suggests Earth's tectonic activity peaked 1.1 billion years ago
Russian researcher claims to have found rocks from object that caused Tunguska explosion
Scientists find Moon, asteroids share history
(Phys.org) —NASA and international researchers have discovered that Earth's moon has more in common than previously thought with large asteroids roaming our solar system.
Los Alamos science sleuth on the trail of a Martian mystery
(Phys.org) —When it comes to examining the surface of rocks on Mars with a high-powered laser, five is a magic number for Los Alamos National Laboratory postdoctoral researcher Nina Lanza.
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 confirms first drilled Mars rock sample
(Phys.org)—NASA's Mars rover Curiosity has relayed new images that confirm it has successfully obtained the first sample ever collected from the interior of a rock on another planet. No rover has ever drilled ...
New study suggests Earth's lower mantle penetrated by metallic blobs
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 ...
Oceanic islands preferred thin crust
(Phys.org)—Debate over how and where oceanic island chains, like Hawaii, form, is at an end according to an academic from The Australian National University.
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 ...
