Scientists to Io: Your volcanoes are in the wrong place
(Phys.org) —Jupiter's moon Io is the most volcanically active world in the Solar System, with hundreds of volcanoes, some erupting lava fountains up to 250 miles high. However, concentrations of volcanic ...
Mercury may have harbored an ancient magma ocean, paper reveals
By analyzing Mercury's rocky surface, scientists have been able to partially reconstruct the planet's history over billions of years. Now, drawing upon the chemical composition of rock features on the planet's ...
India joined with Asia 10 million years later than previously thought
The peaks of the Himalayas are a modern remnant of massive tectonic forces that fused India with Asia tens of millions of years ago. Previous estimates have suggested this collision occurred about 50 million ...
Exploding star missing from formation of solar system
(Phys.org)—A new study published by University of Chicago researchers challenges the notion that the force of an exploding star prompted the formation of the solar system.
NASA study shows Antarctica's Larsen B ice shelf nearing its final act
A new NASA study finds the last remaining section of Antarctica's Larsen B Ice Shelf, which partially collapsed in 2002, is quickly weakening and likely to disintegrate completely before the end of the decade.
New trigger for volcanic eruptions discovered using jelly and lasers
Scientists have made an important step towards understanding how volcanic eruptions happen, after identifying a previously unrecognised potential trigger.
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 ...
Gravity data show that Antarctic ice sheet is melting increasingly faster
During the past decade, Antarctica's massive ice sheet lost twice the amount of ice in its western portion compared with what it accumulated in the east, according to Princeton University researchers who ...
New Mercury surface composition maps illuminate the planet's history
Two new papers from members of the MESSENGER Science Team provide global-scale maps of Mercury's surface chemistry that reveal previously unrecognized geochemical terranes—large regions that have compositions ...
Gullies on Vesta suggest past water-mobilized flows
(Phys.org)—Protoplanet Vesta, visited by NASA's Dawn spacecraft from 2011 to 2013, was once thought to be completely dry, incapable of retaining water because of the low temperatures and pressures at its ...
Scientists find meteoritic evidence of Mars water reservoir
(Phys.org)—NASA and an international team of planetary scientists have found evidence in meteorites on Earth that indicates Mars has a distinct and global reservoir of water or ice near its surface.
Why Iceland formed so differently from the gentle early Earth
How do you take the temperature of the Earth billions of years ago? The answer lies in the rocks.
Study of Chile earthquake finds new rock structure that affects earthquake rupture
Researchers from the University of Liverpool have found an unusual mass of rock deep in the active fault line beneath Chile which influenced the rupture size of a massive earthquake that struck the region ...
Early Earth less hellish than previously thought
Conditions on Earth for the first 500 million years after it formed may have been surprisingly similar to the present day, complete with oceans, continents and active crustal plates.
