About 50 million years ago, a blue dwarf galaxy plunged directly through the larger galaxy, nicknamed “the Bullseye.” The aftermath sent shockwaves into space, causing gas, dust, and stars to move both inward and outward, collecting into a series of 9 concentric rings, similar to a galaxy’s spiral arms. A thin trail of gas 130,000 light-years long connects the two galaxies together. This image was taken by the Hubble space telescope. It is 567 million light years away.
