Starburst Galaxy, NGC 253
Located in Sculptor it is one of the brightest galaxies in the Southern Sky and probably the closest starburst galaxy to us (distance around 10Mly). Seen almost edge-on it contains a bright yellow core, numerous blue star clusters, red emission nebulae and mysterious dark dust lanes.
