Hubble has recorded intriguing hints of an interaction, if not a full-blown merger, between galaxies that include the quasar J0742+2704. There is evidence of a distorted tidal tail, or stream of gas, being pulled outward by the gravity of a nearby galaxy. The presence of a ring galaxy also suggests an interaction: the unique shape of ring galaxies is thought to be the result of one galaxy passing through another, causing its contents to be redistributed into a central core surrounded by stars and gas.
