Pollution Offsets U.S. West Ozone Gains

A newly published study reveals that a combination of naturally occurring atmospheric processes and pollutants crossing the Pacific Ocean from China have offset the reduction of ozone-forming pollutants from the United States. New research finds that the western United States reduced its production of ozone-forming pollutants by a whopping 21 percent between 2005 and 2010, […]

NASA's MMS Formation Will Give Unique Look at Magnetic Reconnection

NASA’s Magnetospheric Multiscale Mission is poised to give astronomers a unique look at magnetic reconnection. On July 9, 2015 the four spacecraft of NASA’s Magnetospheric Multiscale, or MMS, mission began flying in a pyramid shape for the first time. The four-sided pyramid shape—called a tetrahedron—means that scientists’ observations will be spread out over three dimensions. […]

Tahoe State of the Lake Report 2015

New research from UC Davis and NASA reveals that the blueness of Lake Tahoe is controlled by algal concentration, which in turn is driven by the level of nutrients available to the algae. Lake Tahoe’s iconic blueness is most strongly related to algae, not clarity, according to research released today from the UC Davis Tahoe […]

New Research Sheds Light on the Evolutionary Path That Enabled Life on Earth

A new study from the University of British Columbia reveals that the early loss of radioactive heat-producing elements such as uranium and potassium helped put our planet on the evolutionary path to sustain life. Compared to its celestial neighbors Venus and Mars, Earth is a pretty habitable place. So how did we get so lucky? […]

ESA Shows Volume of Arctic Sea Ice Has Increased

New measurements from ESA’s CryoSat Satellite show that the volume of Arctic sea ice increased following the unusually cool summer of 2013, suggesting that ice in the northern hemisphere is more sensitive to changes in summer melting than it is to winter cooling. Scientists at University College London (UCL) and the University of Leeds in […]

Deep Space Climate Observatory Satellite Captures "EPIC" Earth Image

NASA’s Deep Space Climate Observatory Satellite has captured its first view of Earth. The image shows the entire sunlit side from one million miles away. This color image of Earth was taken by NASA’s Earth Polychromatic Imaging Camera (EPIC), a four megapixel CCD camera and telescope. The image was generated by combining three separate images […]

Researchers Identify Zebra-Like Stripes of Plasma in Space

A team of researchers from MIT and UCLA have identified zebra-like stripes of plasma in a region of space about 12,000 miles from Earth’s surface. The structure may help scientists identify radiation-remediation strategies in space. Since the early 1970s, orbiting satellites have picked up on noise-like plasma waves very close to the Earth’s magnetic field […]

Oceans Temporarily Hide Global Warming

A newly published NASA study shows that the recent extra heat from greenhouse gases has been trapped in the waters of the Pacific and Indian oceans, accounting for the slowdown in the global surface temperature trend observed during the past decade. Researchers Veronica Nieves, Josh Willis and Bill Patzert of NASA’s Jet Propulsion Laboratory (JPL), […]

NASA Shows Surfer-shaped Waves in Near-Earth Space

Two published papers reveal Kelvin-Helmholtz waves at the boundaries of near-Earth space, showing that they can appear under any conditions and are much more prevalent than previously thought. The universe overflows with repeating patterns. From the smallest cells to the largest galaxies, scientists are often rewarded by observing similar patterns in vastly different places. One […]

New NASA Estimates of Liquid Assets

A newly published study from NASA helps answer questions about droughts, flooding and how much water is on the move and where it is going. The new study provides estimates for the global water cycle budget for the first decade of the 21st century, taking the pulse of the planet and setting a baseline for […]

Beijing Physical Area Quadrupled in Size in a Decade

Using data from NASA’s QuikScat satellite, a newly published study demonstrates how to quantify urban growth based on observed changes in physical infrastructure. Scientists used this new technique to study the rapid urban growth in Beijing, China, finding that its physical area quadrupled between 2000 and 2009. A team led by Mark Jacobson of Stanford […]

Tiny Dracula Ants: New Species of Subterranean Hunters

Six new species of subterranean ants from the genus Prionopelta have been discovered in Madagascar and the islands of Seychelles. Dubbed Dracula ants by these researchers, this group of ants live underground and engage in strange behavior. Researchers from the California Academy of Sciences (Rick Overson and Brian Fisher) have described six new species of […]

A study of the demise of the Laurentide Ice Sheet that once covered Canada may help scientists better understand shrinking ice fields today - like this melting ice margin in Greenland.

Researchers at Oregon State University studied the cause of the demise of the massive Laurentide Ice Sheet during the last ice age, looking for clues as to how a warming climate may impact ice sheets on Greenland and Antarctica. A new study has found that the massive Laurentide ice sheet that covered Canada during the […]

AIM Spacecraft Observes Noctilucent Clouds

This composite image shows noctilucent clouds over the Arctic captured by NASA’s Aeronomy of Ice in the Mesosphere Spacecraft. In the late spring and summer, unusual clouds form high in the atmosphere above the polar regions of the world. As the lower atmosphere warms, the upper atmosphere gets coooler, and ice crystals form on meteor […]

Study Shows a Third of Big Groundwater Basins in Distress

Using data from NASA’s Gravity Recovery and Climate Experiment satellites, two new studies reveal that about one third of Earth’s largest groundwater basins are being rapidly depleted by human consumption. This means that significant segments of Earth’s population are consuming groundwater quickly without knowing when it might run out, the researchers conclude. The findings are […]

Understanding the Softness in Earth’s Lithosphere

A new model from researchers at Yale University helps explain the drop in elastic stiffness in the middle of the Earth’s continental lithosphere. Lithosphere is the stiff layer of rock that lies atop the slow-motion convection of Earth’s solid, yet ductile, interior. It is the “plate” of plate tectonics, the system of interlocking fragments that […]
