As the European Rosetta spacecraft continues to explore Comet 67P/Churyumov-Gerasimenko as it gradually gets closer to the sun, it's having to deal with some very inclement orbital weather.
The comet being studied by Europe's Rosetta spacecraft may be made entirely of pebbles, challenging currently held theories of how bodies form in the far reaches of the solar system.
There is an exclusive group of celestial bodies that are known to possess rings in our solar system -- now a second asteroid-comet hybrid has been found to sport one.
During the Rosetta's close flyby of comet Comet 67P/Churyumov-Gerasimenko on Feb. 14, the European spacecraft snapped images of the comet's 'belly' revealing a shadow of itself surrounded by a halo.
Astronomers have discovered a star that carried out a stellar hit-and-run 70,000 years ago... and our solar system was the victim.
From a distance of 100 kilometers, the European Rosetta mission captured a stunning overall view of Comet 67P/Churyumov-Gerasimenko and its strengthening jets of vapor.
Comets are weird. And they're about to get weirder.
Early results from Europe’s ongoing Rosetta comet mission show the icy body, believed to be a remnant from the formation of the solar system, is far more complex and diverse than scientists expected.
