Have a look at Alpha Scorpii or Antares which means 'Rival of Mars'.
Mars is the Roman god of war and Ares is the Greek equivalent. Mars and Antares (Anti-Mars) are very similar in colour and sometimes brightness, the latter depending on the distance to Mars.
The Great Orion Nebula (M42) is not a galaxy but a diffuse nebula and is probably one of the easiest and best known non-stellar objects and visible to the unaided eye.
