In eastern edge of the Hydra, it's a deep sky object lying about 5 degrees northeast from M83, a spiral galaxy about 150 millions light years away. You can see in this image that the galaxy has only dimmed central nucleus and indistinct dark lane crossing. But larger telescopes have captured the galaxy has a clear dark lane being warped. Now it's unknown why such an anomalous structures formed, but some hypotheses has been set up that the galaxy has influenced by nearby galaxy or ancient collision has remained the structures.
