The upper galaxy in this image, NGC 7285, is 2' in size while NGC 7284 below it is just 1.5' across
but together these two galaxies in Aquarius are performing a close gravitational dance and the
encounter has produced two magnificent broad tidal tails. This cosmic gravitational stretching has
resulted in stars and gas being flung out and strewn across an area of sky measuring some 10' X 3'.
At the estimated distance of 210 Million light years to this pair of galaxies, this means the two
galaxies have spread across more than 300,000 light years of space, or three times the size of our Milky Way galaxy!
