Messier 77 was discovered by Pierre Méchain in 1780, who originally described it as a nebula. Méchain then communicated his discovery to Charles Messier, who subsequently listed the object in his catalog.Both Messier and William Herschel described this galaxy as a star cluster. Today, however, the object is known to be a galaxy.
Are those false color pictures or real ones? I love the universe.

Love this idea, funny story Herschel was also a composer. I read that his symphonies were often inspired by his work in astronomy.
Cool ! I never knew that
