[CLICK ON IMAGE FOR HIGH RESOLUTION, Ron Garan, STS-134 Crew, Expedition 28 Crew, NASA] Where did all these high energy positrons come from? The Alpha Magnetic Spectrometer (AMS-02) onboard the International Space Station (ISS) has been meticulously recording how often it is struck by both high energy electrons and positrons since 2011. After accumulating years […]
[CLICK ON IMAGE FOR HIGH RESOLUTION / NASA, JPL-Caltech, MSSS How did these Martian rocks form? As the robotic Curiosity rover has approached Pahrump Hills on Mars, it has seen an interesting and textured landscape dotted by some unusual rocks. The featured image shows a curiously round rock spanning about two centimeters across. Seemingly a […]
CLICK ON IMAGE FOR HIGH RESOLUTION / ESA / Rosetta / MPS for OSIRIS Team; MPS/UPD/LAM/IAA/SSO/INTA/UPM/DASP/IDA/Elisabetta Bonora & Marco Faccin (Alive Universe Images) Spacecraft Rosetta continues to approach, circle, and map Comet Churyumov-Gerasimenko. Crossing the inner Solar System for ten years to reach the vicinity of the comet last month, the robotic spacecraft continues to […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, Hubble Legacy Archive, NASA, ESA, Judy Schmidt] The center of the Lagoon Nebula is a whirlwind of spectacular star formation. Visible near the image center, at least two long funnel-shaped clouds, each roughly half a light-year long, have been formed by extreme stellar winds and intense energetic starlight. The […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, Cassini Imaging Team, SSI, JPL, ESA, NASA] Acquiring its first sunlit views of far northern Saturn in late 2012, the Cassini spacecraft’s wide-angle camera recorded this stunning, false-color image of the ringed planet’s north pole. The composite of near-infrared image data results in red hues for low clouds and […]
President Obama went back to his vacation on Martha’s Vineyard Tuesday evening following less than 48 hours in Washington, leaving people puzzled over why he came back in the first place. … Administration officials have insisted for weeks that the president just wanted to return to the White House for a series of meetings, but […]
CLICK ON IMAGE FOR HIGH RESOLUTION / Ron Garan, ISS Expedition 28 Crew, NASA [People on] planet Earth typically watch meteor showers by looking up. But this remarkable view, captured on August 13, 2011 by astronaut Ron Garan, caught a Perseid meteor by looking down. From Garan’s perspective onboard the International Space Station orbiting at […]
So DARPA wants a reusable spaceplane. I mean, who doesn’t? For decades, space experts have tried to design quick-turnover, reusable launch systems. So far, however, no one has made one that works. “There really isn’t any kind of vehicle today that does exactly what they’re asking people to do,” Micah Walter-Range, director of research and […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, M31: The Andromeda Galaxy, Image Credit & Copyright: Jacob Bers (Bersonic)] Andromeda is the nearest major galaxy to our own Milky Way Galaxy. Our Galaxy is thought to look much like Andromeda. Together these two galaxies dominate the Local Group of galaxies. The diffuse light from Andromeda is caused […]
[CLICK ON IMAGE FOR HIGH RESOLUTION, Carlos Di Nallo] What happened to half of Saturn? Nothing other than Earth’s Moon getting in the way. As pictured above on the far right, Saturn is partly eclipsed by a dark edge of a Moon itself only partly illuminated by the Sun. This year the orbits of the […]
