Distant polar-ring galaxy


Anyone can explain this hula hoop playing galaxy ?

I can give theorizing a try! My guess is that the edge-on yellow lenticular/disc galaxy we see encountered a gas-rich companion that took a side-swipe to this likely massive galaxy before entering into a ring-like orbit as it was torn to shreds or, as in some extremely rare cases, the galaxy accreted an extremely large extragalactic hydrogen gas cloud that wrapped around the galaxy in loops before collapsing to form stars in the configuration we see here. Many other possibilities exist, but these are my two likely guesses as examples for both exist in current literature.
