  2. A Yale-led research group has discovered “Bullseye,” a galaxy with nine rings that may help astronomers better understand galaxy evolution and dark matter.

    LEDA 1313424, aptly nicknamed the Bullseye, is two and a half times the size of our Milky Way and has nine rings — six more than any other known galaxy. High-resolution imagery from NASA’s Hubble Space Telescope confirmed eight rings, and data from the W. M. Keck Observatory in Hawaii confirmed a ninth.
