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 ...
Astronomers said Thursday they had found a planetary system with three super-Earths orbiting a bright, dwarf star—one of them likely a volcanic world of molten rock.
A series of earthquakes and shifting ground on the slopes of Kilauea have scientists wondering what will happen next at one of the world's most active volcanos.
University of Utah seismologists discovered and made images of a reservoir of hot, partly molten rock 12 to 28 miles beneath the Yellowstone supervolcano, and it is 4.4 times larger than the shallower, long-known magma chamber.
To understand when and why volcanoes erupt, scientists study the rocks left behind by eruptions past. A method called geobarometry uses the composition of volcanic rocks to estimate the pressure and depth at which molten ...
Splash form tektites are tiny pieces of natural glass created out of spinning drops of molten rock flung from the earth during an extra-terrestrial impact—when the earth is hit by asteroids or comets. They come in a myriad ...
Call it a holiday gift from Pele. Lava from the mountain believed to be home to the Hawaiian volcano goddess has stalled on its slow creep toward a Big Island shopping center.
Lava from an active volcano on Hawaii's Big Island slowed slightly but stayed on track to hit a shopping center in the small town of Pahoa.
New research into an Icelandic eruption has shed light on how the Earth's crust forms, according to a paper published today in Nature.
Lava flowing from a Hawaii volcano is inspiring innovative ideas from schoolchildren on how to deal with the effects of the molten rock.
