(See description below)Arp 286 Galaxy Trio
sweeping spiral arms and obscuring dust lanes, NGC 5566 is enormous,
about 150,000 light-years across. Just to its upper left lies small,
blue NGC 5569. To the right, the third galaxy, NGC 5560, is
multicolored and apparently stretched and distorted by its interaction
with NGC 5566. The galaxy trio is included in Halton Arp's 1966 Atlas of Peculiar Galaxies as Arp 286. Of course, such cosmic interactions are a common part of the evolution of galaxies.
