APOD: NGC 5905 and NGC 5908

Two galaxies, NGC 5905 and 5908, are meeting in the constellation Draco. Each is about 140 million light-years away from Earth, and about 500,000 light-years away from each other. Both are spiral galaxies viewed from different angles, showcasing the variety of possible images that can be seen when viewing these galaxies. NGC 5905 has several bright star clusters branching out from its central bar. 5908 is viewed on edge; the central nucleus can be seen as very bright, partially obscured by a dark line indicative of its disk. NGC 5908 is very similar to another spiral galaxy, the Sombrero Galaxy, whose shape is caused by an unusually large central group of stars, giving it a "hat-like" appearence
