M27

The Dumbbell planetary nebula is located in the constellation of the Little Fox. It is the first planetary nebula observed in the history of astronomy by Charles Messier in July 1764.

Like other planetary nebulae, unlike usual nebulae, it is made up of different successive layers that become visible depending on the filters used. Indeed, in color version, its name of Dumbbell Nebula is aptly named because of its shape. However, by using more restrictive filters, we can then bring out the cross that crosses it and the cloud of gas that escapes on the sides like a sort of halo.

A planetary nebula finds its origin in a star at the end of its life that expels its matter from its outer layers into space. Indeed, as the star uses its fuel, it loses mass and its gravitational attraction decreases, allowing part of its envelope to escape. A similar fate awaits our solar system since our sun will suffer the same fate although it will have a period of expansion before that. The dying star is located in the center and has a real luminosity 100 times greater than our solar star. However, we perceive a radiation of only a third of our sun because it is emitted mainly in wavelengths outside the spectrum visible to our eyes.
