NGC 7525 (= PGC 70731)
Discovered (Nov 3, 1864) by Albert Marth (538)
Two spiral galaxies in Pegasus
NGC 7525 NED02 = A 14th-magnitude spiral galaxy (type S?) at RA 23 13 40.4, Dec +14 01 17
NGC 7525 NED01 = A 15th-magnitude spiral galaxy (type S) at RA 23 13 40.2, Dec +14 01 27
(Note: NED02 is listed in most catalogs as an elliptical galaxy, but the closeup below shows that it is a spiral; hence its designation as such in the entry above.) The two galaxies which comprise NGC 7525 have about the same recessional velocity (as discussed below), and are therefore at nearly the same distance. However, there is no obvious tidal distortion in the image below, so they may not be as close as they appear (although even if they are separated by several million light years, that would be nothing in comparison to their half billion light year distance from us). Face-on NED02 obviously lies in front of edge-on NED01, but their separation is unknown and probably unknowable, given the caveats listed above. Their recessional velocities (11945 km/sec for NED01 and 12260 km/sec for NED02), if used in a straightforward calculation, would indicate a distance of about 555 to 570 million light years. However, for objects at that distance, it is necessary to take into account the expansion of the Universe during the time it took their light to reach us. Doing that shows that the two galaxies were about 545 million light years away when the light by which we see them was emitted, about 555 million years ago (the difference between the two numbers being due to the expansion of the intervening space during the light-travel time). Given that and their apparent sizes (about 0.35 by 0.35 arcmin for face-on NED02, and 0.45 by 0.1 arcmin for edge-on NED01), NED01 is about 70 thousand light years across, and NED02 about 60 thousand light years in size. Since NED01 is nearly edge-on, it is difficult to say much about its detailed structure; but face-on NED02 is a starburst galaxy, and also a Seyfert galaxy (type Sy1.5). |

Discovered (Sep 2, 1836) by John Herschel

Apparent size about 4.5 by 1.7 arcmin.
