Image Description:
Wolf-Rayer stars are an unusual type of heavy and dense stars, on which Hydrogen is completely depleted. For this reason, the star fuses heavier elements. Through spectral analysis it's possible to find what elements are being fused in the surface of the star. Ionized Helium and Nitrogen are common elements. Gravity is huge in these stars, but still once in a while a stellar burp ejects material in all directions.
The Crescent Nebula (NGC 6888, Caldwell 27, Sharpless 105) is formed by the collision of two solar winds (the above mentioned burps), one slower and the second reaching the first at high speed. On the background, we see part of the Cygnus Stellar Cloud (DR 22).
