Swift took a 330 picture mosaic of our nearest respectably sized neighbour galaxy, the venerable, and naked eye Andromeda, aka M31. They used the itsy bitsy little Ulvtravioler/Optical telescope on board, which has surprisingly decent UV capability.

The UV images preferentially trace young hot stars, and so are mostly showing where current star formation is taking place.
