Ring Nebula in Lyra constellation (M 57)
M 57 in the Lyra constellation
Distance: 2,412 light years from Earth
The famous Ring Nebula (M 57) in the constellation of Lyra is often viewed as the prototype of a planetary nebula; it
is one of the magnifi cent features of the Northern Hemisphere's summer sky. Recent studies have shown that it is
probably comprised of a ring (torus) of brightly shining material that surrounds the central star (only visible with larger
telescopes), and not of a gas structure in the form of a sphere or an ellipse.
If you were to look at the Ring Nebula from the side, it would look like the Dumbbell Nebula (M27). With this object,
we're looking directly at the pole of the nebula.

M 27 in the Fox constellation
Distance: 1,360 light years from Earth
The Dumbbell Nebula (M 27) in the Fox constellation was the fi rst 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 you could see the Dumbbell Nebula from one of its poles, it would probably reveal that
it's in the shape of a ring, and we would see something very similar to what we know from the Ring Nebula (M 57).
In reasonably good weather, we can see this object well even at small magnifi cations.
