M27 – The Dumbbell Nebula

Discovered by Charles Messier on July 12, 1764 which he described as an oval nebula without any stars. We see this nebula on it’s equatorial plane in the constellation, Vulpecula. If we saw it from one of it’s poles it would possibly take on the same shape as M57 – The Ring Nebula. With a diameter of roughly 6 arc minutes, and a fainter region expanding upwards of 15 arc minutes, makes it one of the brighter planetary nebula in the sky at a magnitude 7.4. The distance of the nebula is not very well known, but is estimated by most at 1360 light years from Earth. The central star of M27, which formed the beautiful nebula, is at a much dimmer magnitude, 13.5.

This nebula is actually quite bright considering it’s size making it quite easy to spot in most backyard telescopes. Colors are not visible, but you can make out the dumbbell shape of the brighter portions of the nebula.
