Planetary Nebulae (pronounced neb-ue-lee), are among the most diverse and beautiful objects in the universe. Nebulae are clouds of dust and gas. They come in many different forms: Bright Nebulae (Reflection Nebulae and Emission Nebulae), Dark Nebulae, Planetary Nebulae, and Supernovae Remnants. Planetary Nebulae are not actually related to planets at all. They were given this name because when they were first discovered they resembled planets. Planetary Nebulae are the results of the deaths of sun-like stars. The cores of the stars collapse and the outer layers expand outward from the core. The Sun will become a planetary nebula in about 5 billion years.
If a planetary nebula on the list has an M in front of a number that means it is on the list compiled by Charles Messier. His list is most of the best objects to see from Earth.
These are the planetary nebulae in this archive.
