NASA’s MAVEN spacecraft detects Auroras around MarsWritten by Tony Phillips
In late December 2014, NASA’s MAVEN spacecraft detected evidence of widespread auroras in Mars’s northern hemisphere. The “Christmas Lights,” as researchers called them, circled the globe and descended so close to the Martian equator that, if the lights had occurred on Earth, they would have been over places like Florida and Texas. “It really is amazing,” says Nick Schneider who leads MAVEN’s Imaging Ultraviolet Spectrograph (IUVS) instrument team at the University of Colorado. “Auroras on Mars appear to be more wide ranging than we ever imagined.” ![]() A map of MAVEN’s Imaging Ultraviolet Spectrograph (IUVS) auroral detections in December 2014 overlaid on Mars’ surface. The map shows that the aurora was widespread in the northern hemisphere, not tied to any geographic location. The aurora was detected in all observations during a 5-day period.

There’s an arc of learning about combustion that stretches from the earliest campfires of primitive humans to the most advanced automobiles racing down the superhighways of the 21st century. «Read the rest of this article» Sections: Technology | No Comments
NASA’s SAGE III to monitor the Earth’s fragile Ozone LayerWritten by Dr. Tony Phillips
Yet without it, life on Earth would be impossible. A fragile layer of ozone 25 km above Earth’s surface is all that stands between us and some of the harshest UV rays from the sun. The ozone molecule O3 blocks radiation which would otherwise burn skin and cause cancer. «Read the rest of this article» Sections: Technology | No Comments
NASA prepares to study the Mysterious Arc of Venus during it’s Transit of the Sun June 5thWritten by Dr. Tony Phillips
“I was flabbergasted when I first saw it during the 2004 transit,” recalls astronomy professor Jay Pasachoff of Williams College. “A bright, glowing rim appeared around the edge of Venus soon after it began to move into the sun.” For a brief instant, the planet had turned into a “ring of fire.” ![]() The Arc of Venus observed during the planet's 2004 transit by amateur astronomer André Rondi using a 10-cm refractor near Toulouse, France. «Read the rest of this article» Sections: Technology | No Comments
