Located in the constellation Cygnus. Is an emission nebula located 5,000 light-years away from us. Formed from a Wolf-Rayet star, the WR 136 (HD192163). This process began 250,000 to 400,000 years ago, although the star appears to have age of just 4,500,000 years. The formation of this Nebula is due to the strong solar wind emitted from this red giant (this material is blown with 3,000,000 miles per hour) and collides with material that emitted from the same star at an earlier stage of his life. The speed of the material at the earlier stage of his life he was only on the order of 20,000 miles per hour. The star burned so extremely fast, eliminating mass corresponding to that of our Sun every 10,000 years (extremely small time limit for stars, if we consider that our Sun is about 4.5 billion-million years). He is a star who is a candidate in a short time to put an end to his life with spectacular supernova explosion, approximately after 100 to just 200,000 years! Hypermassive  stars have spectacular lifes!!!
