New Image Shows the Advance of Hubbard Glacier

May 20, 2015


The Hubbard Glacier

New data from the Operational Land Imager on Landsat 8 shows the advance of Hubbard Glacier. Since measurements began in 1895, Alaska’s Hubbard Glacier has been thickening and steadily advancing into Disenchantment Bay. The advance runs counter to so many thinning and retreating glaciers nearby in Alaska and around the world. This image, acquired by […]

A Crucial Difference in the Fingerprints of Earth and the Moon

A newly published study brings scientists one step closer to understanding the close familial relationship between Earth and the moon. College Park, Maryland – Scientists at the University of Maryland are the first to confirm the accepted model of the moon’s formation using the “fingerprints” of the moon and Earth. The results suggest that the […]

Terra Satellite Sees Shadows of Solar Eclipse in the Arctic Ocean

March 23, 2015


Terra Satellite Views Shadows of Solar Eclipse

NASA’s Terra satellite captured this view of the clouds in the Arctic Ocean during last week’s total solar eclipse. During the morning of March 20, 2015, a total solar eclipse was visible from parts of Europe, and a partial solar eclipse from northern Africa and northern Asia. NASA’s Terra satellite passed over the Arctic Ocean […]

Van Allen Probes Capture the Effects of a Solar Shockwave

NASA’s Van Allen Probes have captured the effects of a solar shockwave on Earth’s radiation from beginning to end for the first time. On October 8, 2013, an explosion on the sun’s surface sent a supersonic blast wave of solar wind out into space. This shockwave tore past Mercury and Venus, blitzing by the moon […]

NASA Study Shows Carbon Emissions Could Increase Risk of Megadroughts

A new study from NASA reveals that droughts in the U.S. Southwest and Central Plains during the last half of this century could be drier and longer than drought conditions seen in those regions in the last 1,000 years. NASA scientists used tree rings to understand past droughts and climate models incorporating soil moisture data […]
