We Actually Learned a Lot From Philae's Botched Landing on Comet 67/P

The ESA’s attempt to land a probe on Comet 67P/Churyumov-Gerasimenko didn’t go as planned, but the mission has been far from a failure. A recent analysis of Philae’s harrowing journey across the comet has revealed some fascinating clues about its surface, while providing critical insights for future comet missions. » 7/30/15 11:00am 7/30/15 11:00am

What Other Scientists Are Saying About Today's "Life on a Comet" Claim

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 9:40am 11/19/14 9:40am

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… » 11/14/14 1:30pm 11/14/14 1:30pm
