ELEPHANT'S TRUNK NEBULA

The Elephant's Trunk nebula (bottom) is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396, located in the constellation Cepheus about 2,400 light years away from Earth.
The Elephant's Trunk nebula is now thought to be a site of star formation, containing several very young (less than 100,000 years) stars that were discovered in infrared images in 2003. Two older (but still young, a couple of million years, by the standards of stars, which live for billions of years) stars are present in a small, circular cavity in the head of the globule. Winds from these young stars may have emptied the cavity.
