The Elephant's Trunk Nebula is a concentration of interstellar gas and dust within the much larger ionized gas region. IC1396 is located in the constellation Cepheus about 2,400 light years away from Earth. Within this nebula, IC 1396A, commonly called the Elephant's Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim. The bright rim is the surface of the dense cloud that is being illuminated and ionized by a very bright, massive star (HD 206267) that is just to the East of IC 1396A.
