The Highlights of the Year for Space Chris

Rosetta has been in orbit around Comet 67P as the comet went very close to the sun. For the first time we've watched what happens as the comet goes from relatively quiet to being really quite active, and now it's shutting down again. As the comet comes back around the sun, it's been fascinatingly complex. And so these things have gone from being a textbook illustration of a round blob with some jets coming out, to real living complex worlds.
