The Elephant's Trunk nebula is a concentration of interstellar gas and dust in the star cluster IC1396 and ionized gas region located in the constellation Cepheus about 2,400 light years away from Earth. The Elephant Trunk nebula is now thought to be site of star formation, containing several very young (less than 100,000 yr) stars that were discovered in infrared images in 2003.
