| Description | Arp placed this in the "Double Galaxies - Connected Arms" category. His observing notes added: "Arms join at dense knot or nucleus...." My interpretation from the beginning was that we were really looking at 3 galaxies: NGC 6050 (lower left), IC 1179 (upper right) and a third, smaller galaxy at the end of NGC 6050's arm (upper left). Arp's comment suggests he saw the nucleus but wasn't willing to suggest it's a 3rd galaxy. My research discovered the Hubble image you can find in the gallery which confirms it is a third galaxy. The full image is worth studying as it contains many additional interacting galaxies despite a field of view which is only 0.343° x 0.260°. Note Arp 71 which is the "integral sign" galaxy (interacting with a dwarf galaxy on its "toe") higher on the image directly above Arp 272. Overall, the image captures a significant portion of Abell 2151, the "Hercules Cluster", which contains at least 200 galaxies, many of them interacting. |
