Venus may have had a shallow liquid-water ocean and habitable surface temperatures for up to 2 billion years of its early history, according to computer modeling of the planet’s ancient climate by scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York. The findings, published this week in the journal Geophysical Research Letters, […]
Volcanoes are an explosive and mysterious process by which molten rock from Earth’s interior escapes back into the atmosphere. Why the volcano erupts – and where it draws its lava from – could help trace the lifecycle of materials that make up our planet. New University of Washington research shows that a common type of […]
Astronomers have found a unique object that appears to be made of inner Solar System material from the time of Earth’s formation, which has been preserved in the Oort Cloud far from the Sun for billions of years. Observations with ESO’s Very Large Telescope, and the Canada France Hawai`i Telescope, show that C/2014 S3 (PANSTARRS) […]

The seismologist twists the 6-pound seismometer to orient it northward. Then he clicks a cable to a magnetic connection on top. “Starting operation,” says a tinny voice […]
