NGC 7008 (PK 93+5.2), also known as the Fetus Nebula, is a planetary nebula with a diameter of approximately 1 light-year[2] located at a distance of 2800 light years[2] in northern Cygnus. It was discovered by William Herschel in 1787, in Slough, England. NGC 7008 (H I-192) is included in the Astronomical League's Herschel 400 observing program.NGC 7008 is that its intricate and delicate structures make it a fascinating target for both amateur and professional astronomers studying the late stages of stellar evolution and the formation of planetary nebulae.
