Where Is Philae, And When Will It Wake Up?

The hunt for Rosetta's misplaced lander on comet 67P/Churyumov-Gerasimenko is like staring out an airplane window trying to find a washing machine in a field of boulders. These gorgeous new images from the European Space Agency highlight the incredible challenge of finding a tiny robot on a huge comet. » 1/30/15 4:40pm 1/30/15 4:40pm

An Unexpected Discovery On The Surface Of Rosetta's Comet

Scientists have presented their initial observations of Comet 67P/Churyumov-Gerasimenko in seven articles published Thursday in the journal Science. Among the more surprising finds: images of ripples and dunes on the comet's surface, unexpected given that the comet lacks an atmosphere (and therefore wind) and… » 1/22/15 3:30pm 1/22/15 3:30pm

Here's A Peek At Research From This Year's Massive Geoscience Meeting

Every December, geoscientists descend on San Francisco for the American Geophysical Union annual meeting. It's the time for announcements big and small over a daunting diversity of topics. Summarizing the breadth of research is an exercise in futility, so instead, here's a tiny taste of what was shared. » 12/21/14 11:21am 12/21/14 11:21am

Biggest Scientific Breakthroughs Of 2014

This year, humanity landed on its first comet, a child was born to a woman with a transplanted womb, and a fossilized sea shell forced us to reconsider our conceptions of human culture. Those are just a taste of the 20 achievements, innovations, and advances we've selected for our roundup of 2014's biggest… » 12/19/14 12:40pm 12/19/14 12:40pm

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

Thanks To That Shirt, We May Get a Shirt Celebrating Women In Science

It is an incredible day for science when a tiny robot manages to land on a comet. It is an irritating day for science when that gets overshadowed by a poor wardrobe choice. It is a good day for science when that mistake is quickly addressed, and even better when it results in a fantastic new shirt design. » 11/15/14 8:28pm 11/15/14 8:28pm

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 4:30pm 11/14/14 4:30pm

​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 8:00am 11/14/14 8:00am
