Two different cometary perspectives, one from Rosetta and one from the Earth's surface.
The first is of Comet Lovejoy, as it passes by a nice spiral galaxy (at left, in that tail).
The second is from Rosetta, showing bright jets from Comet 67P/Churyumov-Gerasimenko. In just a couple of days, on Valentine's Day, Rosetta will swoop in and come only 6 km from the comet's surface. Those will be some great pictures.
