IC 1396 is a large ionized gas region in the constellation Cepheus, approximately 2,400 light years from Earth. The Elephant's Trunk nebula is a concentration of interstellar gas whose rim is illuminated by the bright star HD206267. The Elephant's Trunk is believed to be a region of star formation, and two very young (1 million years old) stars sit in the cavity at the top of the trunk.
