Glenn's Astrophotography




M27 - also known as the Dumbbell Nebula is the gaseous remnants of the outer layers of a star blown away as it convulsed and collapsed at the end of its nuclear-burning life. This type of nebula is quite common and is known as a "planetary nebula" because it could quite easily be mistaken by an uninformed observer as a planet due to its round shape and apparent size. The remaining core of the original star shines in the center of the nebula and is a planet-sized white dwarf which was probably similar in size to our sun during its nuclear-burning lifetime. M27 lies at a distance of approximately 1200 light years from Earth.
