"Image: A Strange Ring Galaxy"
http://www.physorg.com/news202133035.html
"On the outside is a ring dominated by bright blue stars, while near the center lies a ball of much redder stars that are likely much older. Between the two is a gap that appears almost completely dark."
...
"Hoag's Object spans about 100,000 light years and lies about 600 million light years away toward the constellation of the Snake (Serpens). Coincidentally, visible in the gap (at about one o'clock) is yet another ring galaxy that likely lies far in the distance".
? Two birthing phases ??
Lets see the galaxy modellers work that one out !
