Astronomers Detect Nine Star-Filled Rings around Giant Galaxy
Using data from the NASA/ESA Hubble Space Telescope and the the Keck Cosmic Web Imager (KCWI) at W.M. Keck Observatory, astronomers have identified nine rings — more than previously detected by any telescope in any galaxy — around the collisional ring galaxy LEDA 1313424.
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.

LEDA 1313424 is a ring galaxy discovered in 2019 in the images from the Legacy Survey DR9.
Nicknamed the Bullseye, the galaxy has a redshift of z=0.0394, c...
