Have you ever wondered how big the universe is? Or how small we are in comparison? Let’s take a journey to one of the most fascinating sights in our cosmos: the Cat’s Eye Nebula.

The Cat’s Eye Nebula, also known as NGC 6543 and Caldwell 6, is a planetary nebula. It’s located in the northern constellation of Draco, which was discovered by astronomer William Herschel on February 15, 1786. It was the first nebula of its type to have its spectrum studied, and this work revealed that these nebulae are gaseous, not stellar.
