Last winter, something strange happened on Rosetta’s comet. After a period of calm, the comet began erupting, throwing huge jets of comet dust into space before abruptly stopping. Now, we finally know what happened.
With only a few days left before it’s scheduled to crash-land on the surface of Comet 67P, the Rosetta spacecraft is still yielding amazing discoveries. And I’m not just talking about lost comet landers.
