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.
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.
Solar system simulation reveals planetary mystery
When we look at the Solar System, what clues show us how it formed? We can see pieces of its formation in asteroids, comets and other small bodies that cluster on the fringes of our neighborhood (and sometimes, ...
The bend in the Appalachian mountain chain is finally explained
The 1500 mile Appalachian mountain chain runs along a nearly straight line from Alabama to Newfoundland—except for a curious bend in Pennsylvania and New York State. Researchers from the College of New ...
Rainwater discovered at new depths
University of Southampton researchers have found that rainwater can penetrate below the Earth's fractured upper crust, which could have major implications for our understanding of earthquakes and the generation ...
Meteorite find may be 'missing half' of interstellar collision
Ice-loss moves the Earth 250 miles down
At the surface, Antarctica is a motionless and frozen landscape. Yet hundreds of miles down the Earth is moving at a rapid rate, new research has shown.
