Discovered by Johann Bode in 1779, the Black-Eye Galaxy is noted for a conspicuous dark band of absorbing dust obscuring background features near the core. One theory of this feature is that a former companion galaxy accreted material onto its larger neighbor and it has yet to settle into the orbital plane of the disc, resulting in the present structure we see today. Two counter-rotating discs of stars have been observed in this galaxy, with the interface between these two discs being an area of intense star birth activity which are visible as the blue knots in the prominent dust lane. M64 is approximately 19 million light years distant and spans about 51,000 light years across its major axis.
