NGC_246, also known as the "Dumbbell Nebula," is a planetary nebula located in the constellation Cetus. It is approximately 1,600 light-years away from Earth and has a diameter of about 1.5 light-years. The nebula is formed from the outer layers of a dying star, which have been expelled into space. The central star of NGC_246 is a hot, white dwarf that emits intense ultraviolet radiation, causing the surrounding gas to glow. This nebula is notable for its distinct shape and bright colors, making it a popular target for amateur astronomers and astrophotographers.
