Celestial Antiquity LEDA 1313424
LEDA 1313424 (also known as the Bullseye Galaxy) is a collisional ring galaxy (CRG) located in the Pisces constellation around 551 million light years from Earth. It is notable for its nine identified rings making it the galaxy with the most amount of rings discovered. About 50 million years ago, a blue dwarf galaxy collided with LEDA 1313424 through its central region, initiating a burst of star formation and causing it to have an active galactic nucleus (AGN). The impactor is currently 130,000 light years from LEDA 1313424.
This classification as a CRG is disputed by astronomers including Barry Madore and Alar Toomre. They believe LEDA 1313424 is just a tightly wound spiral galaxy like NGC 488. It is believed that doppler shift measurements of different parts of the galaxy should be able to resolve the dispute.
