IC1396 - Elephant's Trunk Nebula - 250922 - Stereo

The Elephant's Trunk Nebula (IC 1396A) refers to the brightly rimmed shadow of interstellar gas and dust within the much larger emission nebula IC 1396 located in the constellation Cepheus, about 2,400 light years away from Earth. The nebula is a dark, dense region that gets its name from its appearance at visible light wavelengths, where there is a long winding dark patch with a bright rim. The bright rim is the surface of the dense cloud that is being illuminated and ionized by a very bright, massive multiple star (HD 206267) that is just to the east of the Elephant's Trunk Nebula . The entire IC 1396 region is ionized by this massive star, except for dense globules that can protect themselves from the star's harsh ultraviolet rays.
