NGC 3077 is a smaller member of the M81 group. It looks much like an elliptical galaxy. However, it is peculiar for two reasons. First, it shows whispy edges and scattered dust clouds that are probably a result of gravitational interaction with its larger neighbors, similar to the galaxy M82. Second, this galaxy has an active nucleus. This caused Carl Seyfert in 1943 to include it in his list of galaxies, which are now called Seyfert Galaxies. However, NGC 3077, though an emission line galaxy, is today no longer classified as a Seyfert galaxy.
NGC 3077 was discovered by William Herschel on November 8, 1801. He remarked that "On the nF (NE) side, there is a faint ray interrupting the roundness." Admiral Smyth described it as "A bright-class round nebula; it is a lucid white, and lights up in the centre ... between these [stars,] the sky is intensely black, and shows the nebula as if floating in awful and illimitable space, at an inconceivable distance."
