The ESA has released a new 3D shape model of Comet 67P/Churyumov-Gerasimenko. This model integrates the latest images taken by the Rosetta spacecraft, and includes previously unknown features. It can be used for 3D printing or graphical representations. »
Water, water everywhere, but how on Earth did it get here? Many scientists believe that Baby Earth formed dry and was later soaked by an onslaught of extraterrestrial impacts. But a new study challenges that view, arguing that our planet has had water from the start. In fact, we have have inherited it from the tiny… »
It was one year ago today that the Philae Lander bounced, spun, and tumbled across the surface of Comet 67P/Churyumov-Gerasimenko. To commemorate the historic event, the European Space Agency has released an animated video chronicling the lander’s chaotic landing. »
The Rosetta spacecraft has taken hundreds of stunning photographs of Comet 67P/Churyumov-Gerasimenko over the past year, but a portion of the comet was obscured due to its odd seasonal shifts. Now, thanks to a special camera aboard Rosetta, scientists have created a sketch of its elusive dark side. »
When the European Space Agency’s Rosetta spacecraft sent back the first images of Comet 67P/Churyumov–Gerasimenko, scientists were surprised by how much it looked like a rubber ducky. A new analysis finally explains how this comet acquired its distinctive shape. »
If a massive comet struck the Earth, the oceans would boil and the air would catch fire (don’t worry, this isn’t about to happen). But to alien astronomers studying our planet from afar, humanity’s brutal demise would look like nothing more than a faint flicker of light. If we could detect such impacts on distant… »
A new comet is currently making its inaugural trip to the inner Solar System from the Oort cloud where it likely originated. New images show a tremendous amount of dust streaming away from it, along with strange blobs that have attracted the attention of astronomers. »
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. »
Humans, dark and disturbed creatures that we are, love to imagine what would happen if a massive comet struck the Earth. But what if a giant ice rock flung itself into the Sun? A team of astronomers did the math to figure out what would happen. »
The Philae lander, the first probe to ever touch down on a comet, hasn’t made a peep in 11 days, prompting fears that it has shifted its position, and not for the better. »
Photographer Yuri Beletsky recently captured this stunning photo of comet C/2014 Q1 (Pan-Starrs) which is currently visible in the Southern Hemisphere. »
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.
Last week, NASA’s Messenger spacecraft ended its 11-year mission by crashing into Mercury. Of course, Messenger was doomed anyway, but sometimes a mission’s entire point is to smash one thing into a bigger thing and watch the explosion. »
Astronomers have been at a loss to explain Mercury's excessively dark and unreflective surface. But a new study published in Nature Geoscience suggests the innermost planet was painted black by a steady stream of comet dust. The process took millions of years as comets disintegrated close to the sun, shedding carbon… »
