Wolf-Rayet stars are massive stars that shed large amounts of their envelope at the end of their lives through powerful stellar winds. At the same time, their radiation ionises the gas - usually hydrogen and oxygen - and makes it glow, resulting in such beautiful formations as the filigree blue arc in the image above or the well-known crescent nebula NGC 6888 - also in the constellation Cygnus. The creator of the spectacle in the image above is the bright, somewhat pink-looking star in the chain of 4 (2nd from top) to the left of the centre of the image.
