Cat's Eye Galaxy
The Cat's Eye Galaxy, also known as NGC 6543, is a well-known planetary nebula located in the constellation Draco. It is approximately 3,300 light-years away from Earth and is famous for its intricate structure and vibrant colors. The galaxy is shaped like a cat's eye, which is how it got its name, and it features a bright central star surrounded by a series of concentric rings.
Discovered in 1786 by the astronomer William Herschel, the Cat's Eye Galaxy is one of the most studied nebulae in the night sky. Its unique features include a complex pattern of filaments and knots, which are the result of gas ejected from the central star. This nebula provides valuable insights into the life cycle of stars and the processes that occur during their final stages.
