Astronomers Detect Nine Star-Filled Rings around Giant Galaxy

Pasha et al. detected nine rings around LEDA 1313424, a ring galaxy approximately 567 million light-years away in the constellation of Pisces. They also confirmed which galaxy dove through LEDA 1313424, creating these rings: the blue dwarf galaxy that sits to its immediate center-left.
