Early moon model shows heavy metal atmosphere

(Phys.org)—A team of researchers working at NASA's Goddard Space Flight Center has developed a model meant to show what the early moon may have looked like. As they note in their paper uploaded to the arXiv preprint server, ...

At sea, scientists drill into crater for dino clues

Ancient tectonic activity was trigger for ice ages, study says

For hundreds of millions of years, Earth's climate has remained on a fairly even keel, with some dramatic exceptions: Around 80 million years ago, the planet's temperature plummeted, along with carbon dioxide levels in the ...

Expedition recovers mantle rocks with signs of life

An international team of scientists - recently returned from a 47-day research expedition to the middle of the Atlantic Ocean - have collected an unprecedented sequence of rock samples from the shallow mantle of the ocean ...

Underground magma ocean could explain Io's 'misplaced' volcanoes

Tides flowing in a subsurface ocean of molten rock, or magma, could explain why Jupiter's moon Io appears to have its volcanoes in the "wrong" place. New NASA research implies that oceans beneath the crusts of tidally stressed ...
