Constellation Centaurus (Cen)
Description For such a close galaxy, NGC 4945 is easy to miss.   NGC 4945 is a spiral galaxy in the Centaurus Group of galaxies, located only six times farther away than the prominent Andromeda Galaxy.  The thin disk galaxy is oriented nearly edge-on, however, and shrouded in dark dust.  The yellowish/red appearance is caused by about 1 mag of interstellar absorption due to its low galactic latitude. Together with NGC 5128 (Centaurus A) and M 83, it forms part of a small group of galaxies 13 million lightyears away.  At lower left and partly obscured by a mag 8 star, NGC 4945A is an unrelated mag 13 spiral galaxy.  Click on the image for 1600 pixel screen resolution.
