Description

NGC 1232 in Eridanus is an intermediate, barred spiral galaxy about 65,000,000 light-years from Earth. Originally discovered by William Herschel in 1784, it is about 200,000 ight-years across, nearly double our own Milky Way galaxy. Note 'tiny' NGC 1232A at 4 o'clock, just off of the larger galaxy's disk. Together, the two galaxies comprise Arp 41 in Dr. Halton Arp's 1966 Atlas of Peculiar Galaxies. Many thanks go out to my collaborator and friend, Mike Selby, who acquired and calibrated this fine data.
