Constellation Vulpecula (Little Fox):
The Dumbbell Nebula (M 27)
Right Ascension: 19 h 59 m
Declination: +22° 43' (Degrees : minutes)
Distance: 1,360 light years from Earth
The Dumbbell Nebula (M 27) was the first planetary nebula ever discovered. On 12
July 1764, Charles Messier discovered this new and fascinating class of objects. We
see this object almost directly from its equatorial plane. If we could see the Dumbbell
Nebula from one of its poles, we would probably see the shape of a ring, something
very similar to what we know as the Ring Nebula (M 57). In reasonably good weather,
we can see this object well, even with low magnification.
