Object name: ARP016
Arp 16 is better known as M66. It made his atlas under the heading of spiral galaxies with detached segments. It also is part of Arp Arp 317. Making it the only galaxy to have two entries in Arp's atlas. The image seen here was taken back in 2009 under rather poor conditions. The image with Arp 317 was taken under better conditions and processed with more modern tools than I had in 2009. Arp 16 is a rather active galaxy due to interaction with the other members of its group (again see Arp 317). It is this interaction that likely accounts for Arp's "detached segments" seen in this galaxy. To me, they are just clouds of new, blue stars created by interaction with its neighbors.
