M81 – Bode’s Galaxy. Messier 33: Triangulum Galaxy The massive galaxy M87 is the most spectacular example of an elliptical galaxy we can see from Earth. M81 may be undergoing a surge of star formation along the spiral arms due to a close encounter it may have had with its nearby spiral galaxy NGC 3077 and a nearby starburst galaxy (M82) about 300 million years ago.M81 is one of the brightest galaxies that can be seen from the Earth. Messier 52 Messier 84 It is about 12 million light-years from Earth. 1386 in Struve’s grand Catalogue, and by him marked vicinae; the members are both of 9th magnitude, and trend np [north preceding, NW] to sf [south following, SE], about 2″ apart, forming a fine though difficult object.
