Description |
M27
is one of the best known
planetary nebulae in the sky. It
is large and bright and a
popular target with the dumbbell
shape obvious in quite small
telescopes. It is also sometimes
called the apple core nebula.
M27 was the first planetary
nebula to be discovered by
Messier in 1764. Its visual
magnitude is 7.5 and the angular
size is 8.0' x 5.6'. The
distance is estimated to be
about 1360 light years.
