NGC 4580

NGC 4580 is an unbarred spiral galaxy[2] located about 70 million light-years away[3] in the constellation Virgo.[4] NGC 4580 is also classified as a LINER galaxy.[3][5] It was discovered by astronomer William Herschel on February 2, 1786[6] and is a member of the Virgo Cluster.[2][7]

Physical characteristics

NGC 4580 consists of a ringed structure. The inner pseudoring of the galaxy is very well-defined and is made of two tightly wound spiral arms. Three very diffuse spiral arms which are partly defined by dust, split off from the inner pseudoring.[2]

Truncated Disk

NGC 4580 has a severely truncated star-forming disk. This may be due to ram-pressure stripping[2] caused by the infall of the Messier 49 subcluster into the Virgo Cluster.[8] Due to the truncation of the star forming disk, NGC 4580 is classified as an Anemic galaxy.[9]

gollark: Informational texts are kind of less so.
gollark: That's a story. Those are in order.
gollark: Yes, that. I alt-tab lots.
gollark: Podcasts have most of the same problems, too.
gollark: Theoretically you *can* just leave it playing and then do other stuff, but it's easy to be distracted.
