PGC 14030
(= UGC 2885 = CGCG 526-012 = MCG +06-09-012)

A magnitude 13.5(?) spiral galaxy (type SA(rs)bc?) in
Perseus (RA 03 53 03.0, Dec +35 35 25)
Physical Information: Based on a recessional velocity relative to the Cosmic Microwave Background radiation of 5675 km/sec (and H0 = 70 km/sec/Mpc), PGC 14030 is about 265 million light years away, in reasonable agreement with a single redshift-independent distance estimate of about 230 to 235 million light years (the HST press release states that the distance is 232 million light years, but it is impossible to measure such distances that accurately, so even that value should be expressed as 230 to 235 million light years). Given that and its apparent size of about 4.65 by 1.4 arcmin (from the images below), the galaxy is about 315 thousand light years across if at the smaller distance, and about 360 thousand light years across if at the larger distance. Either way, the galaxy is about 2 1/2 times the size and 10 times the mass of our own galaxy, or about 15 million million Solar Masses, and one of the largest spiral galaxies known to exist in our "local" Universe. Despite its enormous size it is only creating new stars at about half the rate of our galaxy, presumably because it is more or less "alone" in space, and has no other galaxies to interact with or consume, processes that tend to stir up star formation. The HST image was taken partly as a commemoration of Vera Rubin, whose studies of the galaxy's rotation helped prove the presence of "dark matter" in galaxies. What "dark matter" is is completely unknown, but the fact that there is something there that we cannot figure out how to observe except through its gravitational effect on visible objects cannot be denied (see Dark Matter In Galaxies).
