DETAILS | NGC488 is a very fine face-on spiral galaxy with tight spiral arms. These arms could be only one or two that have undergone long extension. Supernovae SN 1976G and SN 2010eb occurred here, the latter way out at the very edge. NGC486 is listed as 2 stars but one of them looks remarkably like a distant galaxy. NGC 0490 |
