NGC 6888, known as the "Crescent Nebula," is an emission nebula located in the constellation Cygnus. It's formed by the powerful stellar wind from a Wolf-Rayet star colliding with the surrounding interstellar material, creating its distinctive crescent shape. A fascinating aspect of this nebula is the presence of intricate, filamentary structures illuminated by the energetic radiation emitted by the central star, resulting in a captivating interplay of light and gas.
