The Dust Devils of Mars Could Pack a Seismic Punch
A large dust devil towers over the Martian surface on the plain of Amazonis Planitia, as seen in this High-Resolution Imaging Science Experiment (HiRISE) camera observation taken in 2012. The shadow indicates this dust plume reached a height of 12 miles although it was only 140 yards in diameter.Credit: NASA/JPL-Caltech/Univ. of Ariz. During experiments on […]
International effort reveals Greenland ice loss
One of Greenland’s glaciers is losing five billion tonnes of ice a year to the ocean, according to researchers. While these new findings may be disturbing, they are reinforced by a concerted effort to map changes in ice sheets with different sensors from space agencies around the world. To source

Construction of Giant Next-Generation Telescope Begins in Chile
Chilean President Michelle Bachelet hits a rock with a hammer at the groundbreaking ceremony for the Giant Magellan Telescope at Las Campanas Observatory on Nov. 11. (“Las Campanas” means “the bells” in Spanish; the observatory was named after the curious ringing sound local rocks make when struck.)Credit: Mike Wall/Space.com LAS CAMPANAS OBSERVATORY, Chile — Construction […]
Record-Setting Gamma-Ray Pulsar Beyond Our Galaxy Bursts into View
The Fermi Gamma-ray Space Telescope’s Large Area Telescope caught sight of the first gamma-ray pulsar ever seen outside the Milky Way, PSR J0540-6919, which is also the most luminous gamma-ray pulsar ever found. The telescope also imaged another powerful pulsar nearby, PSR J0537-6910.Credit: NASA’s Goddard Space Flight Center; background: ESO/R. Fosbury (ST-ECF) Researchers have spotted […]
First Gamma-Ray Blasting Pulsar Detected Outside Milky Way | Video
Researchers have dubbed it “the most luminous gamma-ray pulsar known so far.” A rapidly spinning neutron star in the Tarantula Nebula is the first of its kind to be observed in a the Large Magellanic Cloud, a small satellite galaxy.

Earth's Absorption of CO2 May Tilt In Wrong Direction | Video
For at least the past 50 years, about half of all Earth’s carbon dioxide emissions – human and natural – have been absorbed by the land and oceans. Scientists are trying to understand how much more CO2 this global carbon sink can take, before it spills over. Credit: NASA’s Jet Propulsion Laboratory To source
Rural Biomass Burning vs. Megacity Industry: Who Emits More CO2 | 5-Day Time-Lapse Video
Scientists are studying the heat trapping behavior of CO2 released by land-clearing and accidental forest fires vs. factories in large urban centers. The data producing this simulation were taken during a 5-day period in June 2006. Credit: Global Modeling and Assimilation Office, NASA’s Goddard Space Flight Center To source

New Dwarf Planet In Our Solar System May Be The Farthest One Yet
Object V774104 was discovered in late October, 2015, and is one of the most distant objects ever detected. It appears to be about half the size of Pluto, but with an orbit two to three times larger than Pluto’s.Credit: Scott Sheppard, Chad Trujillo and Dave Tholen: Subaru Telescope A newly found object may set a […]
