NGC 6543 (Cat's Eye Nebula)

NGC 6543 (M 0) is a planetary nebula and in the constellation of Dragon. It is also known as the Cat's Eye Nebula. It is approximately 3,300 lightyears away from earth.
This wonderful planetary nebula was discovered by William Herschel already in 1786. It consists of the remnants of an old star that blew its gas out into deep space. The gas will wander through our galaxy and eventually become part of new stars and planets. Planetary nebulas are usually not very old, and the age of the Cat's Eye Nebula is estimated at around 1000 years, not very old on a cosmic scale.
