Atlas Image mosaic, covering 6.0´ × 6.0´ on the sky, of the planetary nebula NGC 6781. Planetary nebulae (PNe) are formed as low-mass stars, like the Sun, reach the end of their lives and lose their outer envelopes to the interstellar medium. NGC 6781 has a very similar "ring-like" morphology to the famous PN, the Ring Nebula (M57). 1999 Sep 29-Oct 5 Posted on: 31 Mar, 2003
