Discovered on September 7, 1782 by William Herschel, NGC 7009 or Saturn Nebula got its name because in small telescopes it almost looks as if the planetary has edge-on rings or even handle bars. This complex planetary is comprised of ansae or “flyers”; multiple shell structures as well as a halo all which add to its beauty and mystery.

This again, is an example of a star that’s near the end of its life and its exposed interior is showering the material which used to be the stars outer layer with ultraviolet radiation which in turn causes it to glow. For more info on planetary nebula formation, here ya go:
