Soul Nebula
The soul nebula ( Sharpless 2-199 or even LBN 667) is an emission nebula in the constellation Cassiopeia.
Construction
Several small open clusters are embedded in the nebula: Cr 34, Cr 632 and Cr 634 in the head and IC 1848 in the fuselage. The object is also commonly known under the name of the latter star cluster IC 1848.
The small emission nebula IC 1871 can be found just to the left above the head of the Seelnenebels, other small emission nebulae such as IC 669 and IC 670 are slightly below.
The complex east of it is its neighbor IC 1805 called the Heart Nebula. Both are often referred to together as the Heart and Soul Nebula.
Between the heart and the soul of the giant elliptical galaxy fog Maffei 1 are located slightly south of a hand, the other hand, the spiral galaxy Maffei 2
Star formation
The W5 is a radio source within the nebula, which occupies an apparent diameter in the sky of 4 full moons and is located at a distance of about 7,500 light years from our solar system in the Perseus arm of the Milky Way in the constellation of Cassiopeia. As in other star-forming regions as well, such as in the Orion nebula or in the Carina Nebula, also exist in the W5 huge voids created by radiation and stellar winds of the biggest stars in this region.
According to the theory of triggered star formation, the gas at the edge of these cavities is compressed, creating a chain of successive origination of new stars is triggered in the fog. The images from the Spitzer Space Telescope provide the best so far confirmations for the theory. The astrophysicist who examined these images could show that the more the shock front from the center there always new young stars are formed, older stars are closer to the center accordingly, outside the mudstone.
