The other galaxy has pulled apart the spiral arms of NGC 772, while the external spiral arms vanish in the intergalactic medium. Image released January 2013.
1. You know, our position in the Milky Way is not all that different
than the area disturbed in NGC 772. We are located in one of the out arms of our pinwheel shaped galaxy. NGC 772 is a pinwheel galaxy being ripped apart and if that were the Milky Way our Sun, and Earth along with it, would have been propelled into the inter-galactic void.
NGC 772 has no doubt been experiencing this onslaught for millions of years.
