M27 - The Dumbbell Nebula
The Dumbbell Nebula - Messier 27 - is a planetary nebula located in constellation Vulpecula (“little fox”) at about 1200 light years from Earth. The term planetary is somewhat misleading since it are not related to planets - the term derives from the fact that these nebulas are round when seen through a telescope. And in fact, M27 was the first planetary nebula to be spotted by Charles Messier.
In reality, these nebulas are the result of stars that shed their outer layers by the end of their life. And in this photo, that star can be seen right in the center of it. And like many of their kind, knots of dust do exist nearby the star, leading to a patterned look near the center.
Interestingly, the colors are associated with the chemical compounds that exist in this region - blue is oxygen and red hydrogen and these are the building blocks of water. No wonder that water is thought to be a common compound in the Universe.
