Planetary Nebula M27 (NGC 6853), type 3a+2, in Vulpecula

RA 19h 59m 40.1s Dec +22 43 39
Magnitude 7.3, distance: approx. 1250 light years;diameter 8.0x5.7 arc seconds.

The Dumbbell Nebula M27 was the first planetary nebula ever discovered. On July 12, 1764, Charles Messier discovered this new and fascinating class of objects, and describes this one as an oval nebula without stars. We happen to see this one approximately from its equatorial plane (approx. left-to-right in our image); from near one pole, it would probably have the shape of a ring, and perhaps look like we view the Ring Nebula M57.
