Led by scientists at NASA’s Jet Propulsion Laboratory and the University of California, Irvine, the study also concludes that Antarctica continues to lose mass, particularly in the Amundsen Sea Embayment and the Antarctic Peninsula on the western part of the continent; however, those losses have been partially offset by gains from increased snowfall in the northeast. ![]() Greenland’s Steenstrup Glacier, with the midmorning sun glinting off the Denmark Strait in the background.

NASA’s Hubble Space Telescope uses new technique to find Small Clumps of Dark Matter
All galaxies, according to this theory, form and are embedded within clouds of dark matter. Dark matter itself consists of slow-moving, or “cold,” particles that come together to form structures ranging from hundreds of thousands of times the mass of the Milky Way galaxy to clumps no more massive than the heft of a commercial airplane. (In this context, “cold” refers to the particles’ speed.) ![]() Each snapshot shows four distorted images of a background quasar (an extremely bright region in the center of some distant galaxies), surrounding the core of a massive foreground galaxy. The gravity of the foreground galaxy magnifies the quasar, an effect called gravitational lensing. (NASA, ESA, A. Nierenberg, T.

NASA’s ER-2 High-Altitude Aircraft surveys Southern California WildfiresWritten by Alan Buis
NASA’s ER-2, based at Armstrong Flight Research Center in Palmdale, California, flies as high as 70,000 feet (21,300 meters), almost twice as high as a commercial airliner. NASA uses the unique perspective of the ER-2 for science research missions over much of the world. ![]() The Ventura coastline is barely visible under a plume of smoke as NASA’s ER-2 high-altitude aircraft carrying JPL’s AVIRIS spectrometer instrument surveys the Southern California wildfires on Dec. 7, 2017.

American Heart Association reports Poor Sleep may increase risk for Irregular Heart RhythmsAmerican Heart Association Meeting Report
Obstructive sleep apnea, sleep interrupted by pauses in breathing, is a known risk for atrial fibrillation – an irregular heartbeat that can lead to strokes, heart failure and other heart-related complications. But whether there’s a relationship between disrupted sleep and atrial fibrillation even when there’s no sleep apnea is unclear. ![]() Poor sleep – even if you don’t have sleep apnea – may be linked to higher risks of developing an irregular heartbeat.

NASA’s Kepler Spacecraft discovers 104 Planets outside our Solar SystemWritten by Elizabeth Landau
These four planets, all between 20 and 50 percent larger than Earth by diameter, are orbiting the M dwarf star K2-72, found 181 light-years away in the direction of the Aquarius constellation. The host star is less than half the size of the sun and less bright. ![]() This artist’s concept shows NASA’s Kepler Space Telescope on its K2 mission. In July 2016, an international team of astronomers announced they had discovered more than 100 new planets using this telescope.

Clarksville Students Seek Fun in the Lab Instead of Fun in the SunWritten by Karin Fielder Weaver and Kelly C. Motes
These academically talented dual-enrollment students recently made the news by finishing their first year at Nashville State Community College (NSCC). Hannah began attending NSCC in June 2015 at the age of 14. To date, she has completed 38 college credits, with a cumulative college GPA of 3.45. «Read the rest of this article» Sections: Education | No Comments
NASA Study compares two types of Southern California FiresWritten by Alan Buis
Both types of fires are predicted to increase by midcentury, but non-Santa Ana fires are expected to increase more. The research could assist policymakers and response agencies in better allocating firefighting resources in the future. ![]() An October 2007 image, left, of Southern California wildfires shows how offshore Santa Ana winds control these events. Wind is less likely to dominate summer fires like the 2009 Station Fire, right. Images from the Moderate Resolution Imaging Spectrometer on NASA’s Aqua satellite.

NASA’s Gemini Planet Imager discovers young Jupiter like planetNASA’s Ames Research Center
The new planet, called 51 Eridani (Eri) b, is the first exoplanet discovered by the Gemini Planet Imager (GPI), a new instrument operated by an international collaboration, and installed on the 8-meter Gemini South Telescope in Chile. ![]() Artistic conception of the Jupiter-like exoplanet 51 Eridani b, with the hot layers deep in its atmosphere glowing through the clouds. Because of its young age, this cousin of our own Jupiter is still hot and carries information on the way it was formed 20 million years ago.

NASA and U.S. Forest Service maps used to help recovery from California MegafiresWritten by Carol Rasmussen
The maps, so detailed that they show individual trees, cover the areas of two California megafires — the 2013 Rim fire, which burned more than 250,000 acres (1,000 square kilometers) near and in Yosemite National Park, and 2014’s very intense King fire near Lake Tahoe — before, during and after the active burns. ![]() The 2013 Rim fire in and near Yosemite National Park, California, was the third largest in the state’s history, burning more than 250,000 acres. Almost two years later, forest restoration efforts are still ongoing. (USFS/Mike McMillan) «Read the rest of this article» Sections: Technology | No Comments
