NGC772 in Aries


NGC 772 is a spiral galaxy in the constellation Aries. It is included in Arp's list of peculiar galaxies. This is an interesting field, because NGC 772 is surrounded by a few eliptical galaxies that are believed to have a tidal impact, causing the fainter outer spiral arm. I was amazed at the sheer number of distant galaxies in this field. They are probably not related to NGC 772 in the center, but there may be a gravitational lens effect at play here, bringing the smaller galaxies into view.
