I am a native in this world And think in it as a native thinks

Astronomy Tuesday



Well, this is very cool.

I posted an image from the surface of comet C67/P Churyumov-Gerasimenko several years ago, commenting that the Rosetta probe wasn't getting a sufficient charge on its solar panels and there might not be any more pictures. But Rosetta, like the Mars Rover, just kept going, and sent this picture last July, shortly before self-destructing. This plume of dust and water-ice emerging from beneath the comet's surface may show how a comet gets its tail.
