3. Rectangular Red Nebula
Found Year: 1973
NASA is the one who discovered it.
Location: The Unicorn, or Monoceros
The clouds of the different nebula found within the infinite galaxies can take on a variety of shapes, just like the white, fluffy clouds in the sky. A prime example of this can be located 2,300 light-years from Earth, nestled in the Monoceros constellation.

Nearly as much remains unknown about the Red Rectangle Nebula’s distinctive “extended red emission” as it did upon its discovery in 1973. The unique geometric shape of the nebula may have been caused by two stars at its centre reflecting twin cones of light through space dust. Of then, it might just be extraterrestrial art.
