 Lying about 500 million light years away, the cartwheel shape of this galaxy is the result of a violent galactic collision. As with the other ring galaxies, the striking ring-like feature is a direct result of a smaller intruder galaxy, possibly one of the two objects to the left of the ring, that careen through the core of the host galaxy. Presumably, the cartwheel galaxy was a normal spiral galaxy like our Milky Way before the collision. This spiral structure is beginning to re-emerge, as seen in the faint arms or spokes between outer ring and the bullseye-shaped nucleus. The ring contains at least several billion new stars that would not have normally been created in such a short time span. The ring is 150,000 light years across. The entire Milky Way galaxy could fit inside.
