Source of volcanoes may be much closer than scientists thought… A long-held assumption about the Earth is discussed in today's edition of Science, as Don L. Anderson, an emeritus professor with the Seismological Laboratory of the California Institute of Technology
Today’s atmosphere likely bears little trace of its primordial self: Geochemical evidence suggests that Earth’s atmosphere may have been completely obliterated at least twice since its formation more than 4 billion years ago. However, it’s unclear what
Van Allen radiation belts have been found to contain a nearly impenetrable barrier that prevents the fastest, most energetic electrons from reaching Earth.The Van Allen belts are a collection of charged particles, gathered in place by Earth’s magnetic field. They
NASA Goddard Space Flight Center scientist Andrew Sayer talks about how emissions from volcanoes can affect clouds. This video provides an overview of research published in the Journal of Atmospheric Chemistry and Physics. Research: Systematic satellite observations of
NASA's sounding rocket experiment has detected a surprising surplus of infrared light in the dark space between galaxies, a diffuse cosmic glow as bright as all known galaxies combined. The glow is thought to be from orphaned stars flung out of galaxies. The finding

According to a new study by Kobe University earth scientists, Japan could be nearly destroyed by a massive volcanic eruption over the next century. The experts said they analyzed the scale and frequency of volcanic eruptions in the archipelago nation over the past 120
Salt-spoiled soils worldwide: 20% of all irrigated lands — an area equal to size of France. Extensive costs include $27 billion+ in lost crop value/year. UNU study identifies ways to reverse damage, says every hectare needed to feed world’s fast-growing popu
Hydraulic fracturing triggered a series of small earthquakes in 2013 on a previously unmapped fault in Harrison County, Ohio, according to a study published in the journal Seismological Research Letters (SRL) on October 14, 2014. Nearly 400 small earthquakes occurred be
Using a first-of-its-kind, high-resolution numerical model to describe ocean circulation during the last ice age about 21 000 years ago, oceanographer Alan Condron of the University of Massachusetts Amherst has shown that icebergs and meltwater from the North American i
A professor at Tohoku University in Japan, Keiji Nagatani, has spent last 10 years developing robotic systems specifically designed to operate in harsh conditions near active volcanoes. Nagatani's aim is to design robots which can go where humans can't and effec
