New Calculations Show Pacific Plate Shrinking as it Cools

A newly published study from geophysicists Rice University and the University of Nevada challenge assumptions about a rigid lithosphere, revealing that the Pacific plate is shrinking as it cools. Houston – The tectonic plate that dominates the Pacific “Ring of Fire” is not as rigid as many scientists assume, according to researchers at Rice University […]

Scientists Detect Evidence of Water in Earths Mantle

New research reveals large quantities of water bound up in the rock located deep in the Earth’s mantle. Researchers have found evidence of a potential “ocean’s worth” of water deep beneath the United States. Although not present in a familiar form, the building blocks of water are bound up in rock located deep in the […]

Earths Atmosphere Contains an Unexpectedly Large Amount of Ozone Depleting Compound

A newly published study from NASA shows that Earth’s atmosphere contains an unexpectedly large amount of Carbon tetrachloride (CCl4), leaving researchers to believe that there are either unidentified industrial leakages, large emissions from contaminated sites, or unknown CCl4 sources. NASA research shows Earth’s atmosphere contains an unexpectedly large amount of an ozone-depleting compound from an […]

Human Contribution to Glacier Mass Loss Has Steadily Increased

By using computer simulations of the climate, researchers have found evidence for anthropogenic glacier mass loss in recent decades. In a paper published in the journal Science, the team reports that about one quarter of the global glacier mass loss during the period of 1851 to 2010 is attributable to anthropogenic causes and that the […]

Meteorite Sheds Light on Dinosaur Extinction

New measurements on the Chelyabinsk meteorite rule out the possibility for the Baptistina Asteroid Family being the source of the K/T impactor. Tucson, Arizonia — A long-standing debate about the source of the asteroid that impacted the Earth and caused the extinction of the dinosaurs has been put to rest thanks to the Chelyabinsk meteorite […]

NASA Preparing to Launch Carbon Observatory

NASA is about to launch the Orbiting Carbon Observatory – a satellite dedicated to the study of global carbon dioxide sources that will help researchers predict the future of climate change. In the lexicon of climate change, one word appears more often than any other: “carbon.” Carbon credits, carbon emissions, carbon sequestration…. These terms are […]

New NASA Animations Show Water Vapor Over Oceans

Scientists have used observations from the National Oceanic and Atmospheric Administration’s Geostationary Operational Environmental Satellites to create two new types of animations that indicate where water vapor is moving over the Atlantic and Eastern Pacific oceans. Knowing where water vapor is in the atmosphere is one of many factors forecasters use to identify weather features. […]

Study Shows Earth is Around 60 Million Years Older Than Previously Thought

New research presented at the 2014 Goldschmidt Geochemistry Conference reveals that the final stage of Earth’s formation is around 60 million years older than previously thought. Sacramento, California, Tuesday June 10, 2014 – Work presented today at the Goldschmidt Geochemistry Conference in Sacramento, California shows that the timing of the giant impact between Earth’s ancestor […]

Solar Wind Breaks Through Earths Magnetic Field

A new study uses data from the four European Space Agency satellites in the Cluster mission to reveal how solar wind breaks through the Earth’s magnetic field. Space is not empty. A wind of charged particles blows outwards from the Sun, carrying a magnetic field with it. Sometimes this solar wind can break through the […]

Study Indicates Loss of West Antarctic Glaciers Appears Unstoppable

A new study led by NASA researchers presents multiple lines of evidence – incorporating 40 years of observations – that rapidly melting section of the West Antarctic Ice Sheet appears to be in an irreversible state of decline. A new ScienceCast video lays out the evidence for irreversible decline of the West Antarctic glaciers. Over […]

Researchers Develop Self Healing Plastic

Researchers from the University of Illinois have developed nonliving, synthetic materials that can heal and regenerate in a way that is reminiscent of some living systems. Champaign, Illinois — Looking at a smooth sheet of plastic in one University of Illinois laboratory, no one would guess that an impact had recently blasted a hole through […]

NASAs Lunar Reconnaissance Orbiter Views Earth

NASA’s Lunar Reconnaissance Orbiter captures a rare view of Earth from the moon. NASA’s Lunar Reconnaissance Orbiter (LRO) experiences 12 “earthrises” every day, however LROC (short for LRO Camera) is almost always busy imaging the lunar surface so only rarely does an opportunity arise such that LROC can capture a view of Earth. On February […]

Researchers Reconstruct Ancient Impact of Massive Asteroid

A newly published study reveals an ancient asteroid impact that left a crater nearly 500 kilometers across: up to two and a half times larger in diameter than the crater formed by the dinosaur-killing asteroid. Washington, D.C. — Picture this: A massive asteroid almost as wide as Rhode Island and about three to five times […]

New Research Shows How and When Earth Developed Its Rigid Tectonic Plates

Newly published research from Yale University and Université de Lyon in France shows how and when Earth developed its rigid tectonic plates and why Venus never has. “We think it all comes down to the behavior of tiny grains of minerals within rocks,” said Yale geophysicist David Bercovici, lead author of research published online April […]
