Its name is Latin for normal, referring to a right angle, and is variously considered to represent a rule, a carpenter’s square, a set square or a level.

- Messier 94 (Wikipedia)
Messier 94 (also known as NGC 4736, Cat’s Eye Galaxy, Crocodile Eye Galaxy, or Croc’s Eye Galaxy) is a spiral galaxy in the mid-northern constellation Canes Venatici. It was discovered by Pierre Méchain in 1781, and catalogued by Charles Messier two days later. Although some references describe M94 as a barred spiral galaxy, the “bar” structure appears to be more oval-shaped. The galaxy has two ring structures.
