Object name: ARP220
Arp 220/IC 4553 is the closest known Ultra Luminous Infra Red Galaxy (ULIRG) known and one of the brightest. Though all this was unknown at the time of Arp's atlas. This was discovered initially by the IRAS satellite. A press conference to announce these objects that the scientists didn't realize were galaxies at the time has been used by, first the believers of the 2003 Zeta/planet X end of the world and then by the 12/21/2012 end of the world believers of "planet Nibiru" to "prove" this mythical planet exists. If it wasn't this galaxy that caused the furor it was one like it. I was a supervisor of a public observatory back when the Zeta fiasco happened and was reviled by some for not showing them this non-existent planet. I don't miss those days.
