Many people find the Andromeda galaxy from the two streams of stars extending from the Great Square (they are the constellation Andromeda). Or they find the galaxy via the constellation Cassiopeia. This photo via EarthSky Facebook friend Cattleya Flores Viray.
The Orion Nebula (M42) and the Coalsack are visible to the unaided eye, and so are the first nebulas discovered. M31, the Andromeda Galaxy, was called a nebula until the 1940s (later for a few conservatives), but was recognized as a true galaxy following the work of Edwin Hubble and Milton Humason.he Andromeda Galaxy was called the Andromeda Nebula before this. Back to the actual answer, the first nebulae were found and cataloged by Charles Messier in the 18th century.
