Friday Galactic Blogging
That's quite a bridge! 22,000 light years long and spanning the gap between the galaxies NGC 5216 and NGC 5218, known collectively as ARP 104. Obviously in close a gravitational relationship, these two galaxies look appear to be in the process of tearing each other up, probably to merge in the next hundred thousand years or so. They're relatively close to us at a distance of about seventeen million light years in the direction of the Big Dipper. It's an APOD image, and you know what to do.
