As Comet 67P/Churyumov–Gerasimenko sneaks closer to the sun, the Rosetta orbiter is capturing dramatic outbursts from the ever-more active comet. This jet was so powerful, it momentarily out-puffed the solar wind, creating a rarely-observed diamagnetic cavity. »
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. »
This morning, several news outlets gave voice to an extraordinary claim: Comet 67P/Churyumov-Gerasimenko, where the spacecraft Philae awoke last month, could be home to alien life. But extraordinary claims, we all know, require extraordinary evidence. So guess what these morning’s claims were lacking! »
This past weekend, the Philae Lander awoke from its 211-day hibernation on Comet 67P/Churyumov–Gerasimenko. The dramatic receipt of signals from the probe triggered renewed activity among mission planners who are now trying to figure out what to do next. Here’s how things could unfold.
After months of searching, the European Space Agency says it may have finally caught a glimpse of the missing Philae Lander on the surface of Comet 67P/Churyumov-Gerasimenko. »
Using the OSIRIS camera aboard the Rosetta spacecraft, ESA scientists have discovered a strange formation of what appears to be balancing boulders on comet 67P/Churyumov-Gerasimenko.
It has been nearly four months since Philae landed on Comet 67P. Because the probe landed in the shadow of a cliff, it couldn't draw sufficient energy from the sun. But later this week, there's a slim chance the probe could awaken and send a signal to the Rosetta spacecraft. »
This past weekend, the Rosetta spacecraft passed within just 3.7 miles (6 km) of the surface of Comet 67P. The images it sent back show the surface of this alien world in extraordinary detail, including some features never seen before. »
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. »
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… »
While sifting through images taken by the Rosetta spacecraft of Comet 67P, an amateur British astronomer has uncovered a previously unknown vertical cliff that looks like something right out of Mordor. »
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. »
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… »
A color image of Comet 67P has finally been released, revealing that it is… grey. The picture is composed of three images taken by Rosetta's scientific imaging system OSIRIS in red, green and blue filters. In reality, it's even darker, but the image has been brightened enough for us to see the comet's features. »
The Rosetta spacecraft has detected some strange water vapor streaming from Comet 67P — water that's significantly different to what we have here on Earth. The startling discovery challenges the popular assumption that much of our water was delivered here by comets. »
Analysis of the comet lander's data suggests it bounced at least three times, and not twice as earlier reported. »
