Glenn's Astrophotography




M97, also known as The Owl Nebula, is one of the fainter objects in Messier's catalog. M97 is a complex planetary nebulae having an inner shell of ionized gas that is enveloped by a fainter outer shell of gas with lower ionization. M97 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. 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. M97 is located approximately 2.6 thousand light-years from earth.
