An Incredibly Detailed Geologic Map Of Giant Asteroid Vesta

Appearing in the December issue of the journal Icarus, this beautiful geologic map of big ol' asteroid/minor-planet Vesta was created by a team led by planetary scientist David Williams, from data collected by NASA's Dawn spacecraft during its 15-month orbit of the oblong object between 2011 and 2012. » 11/21/14 3:02am Today 3:02am

An Ultra HD Time-Lapse Of Earth That Is 100% Worth Watching

It's strange that we can be blasé about space-imagery, our appetites glutted by a steady stream of "mesmerizing," "humbling," and "mindblowing" footage of our planet. It takes more than a view from the ISS to give us pause. So trust us when we say that this video is definitely worth the watch. » 11/20/14 5:59pm Yesterday 5:59pm

An Astounding History of Scientific Space Art from the Past 200 Years

Ron Miller's new coffee table book The Art of Space is a gorgeous history of scientific illustrations, full of retro rockets and stunning planetscapes. It's also a glimpse back at the cutting-edge astronomy of yesteryear. We've got a gallery of some of the most striking work from the book. » 11/20/14 1:01pm Yesterday 1:01pm

Philae's Discovery Of Organic Molecules Is Actually Not A Big Deal

Prior to going into hibernation mode, the Philae lander hurriedly conducted a number of experiments and sent its findings back to Earth. Preliminary analysis shows that the icy and dust-covered comet contains organic molecules. It's a cool discovery, no doubt, but one that shouldn't be exaggerated in terms of its… » 11/19/14 4:28pm Wednesday 4:28pm

This Could Finally Explain How Mars Got Its Liquid Water

Evidence suggests that Mars had water flowing on its surface at various points in its ancient history. But the evidence also points to temperatures being far too cold at those time for water to be liquid. So, how can both facts be true? At last, this paradox may be on the verge of resolution. » 11/18/14 8:16pm Tuesday 8:16pm

Is That Comet We Landed On Singing?

In what was a bit of an unexpected find, Rosetta's Plasma Consortium picked up variations in the magnetic field around the comet, Comet 67P/Churyumov-Gerasimenko. The variations had audible frequencies, and the frequencies ranged from 40-50 millihertz. That frequency range is inaudible to the human ear, so some… » 11/15/14 12:23am 11/15/14 12:23am

​Stunning Images Of A Comet's Alien Landscape

In the weeks prior to the Philae landing, the Rosetta spacecraft maintained an orbit around Comet 67P/CG at less than six miles from its surface. The ESA has just released a collection of previously unpublished images taken by Rosetta's navigation camera, revealing the varied and dramatic terrain of a mysterious world. » 11/14/14 11:38am 11/14/14 11:38am

That Was A Bumpy Landing. Can Philae Still Complete Its Mission?

Yesterday's heroic comet landing was crazier than mission controllers had hoped for. After two wild bounces and no harpoon strikes to anchor it, Philae has settled in the shadow of a cliff. One of its three feet is off the ground. Worse, there there are now concerns about its battery life. » 11/13/14 11:45am 11/13/14 11:45am
