NASA has released a video demonstrating how the asteroid capture mission will unfold -- these are the highlights.
Saturn's rings rain charged water particles down onto the gas
giant's atmosphere, causing measurable changes in the planet's
ionosphere.
For the first time, the European Herschel space observatory
has spied an old subgiant star sporting a dusty disk of debris -- a
feature usually associated with young stars.
