M57, The Ring Nebula, is a planetary nebula located about 2600 ly away in the constellation of Lyra.
Kinematic studies of M57 suggest that it is barrel shaped. It appears as a ring to us because we are looking down the barrel.
This shows that much of the way we see things in space can be a projection effect.
