3.1



This emission nebula, IC 1396, is made up of dark dust clouds and cosmic dust. The nebula is located about 3,000 light-years from Earth, and it stretches across several hundred light-years in size. This nebula is home to a star-forming region, called the Elephant Trunk Nebula, or IC 1396A. It is home to several stars that are less than 100,000 years old. It is a well-known nebula because it emits ligth in a visible wavelength. It alone is nearly 20 light-years long. The nebula, which is located in the constellation Cepheus, gets it's color from the hydrogen gas it emits.
