Description

The Elephant's Trunk Nebula, IC1396A, is a combination of dark and emission nebulae in the constellation Cepheus and lies around 2400 light-years away. The trunk itself spans 20 light years shrouds many young protostars that are in the process of forming. The wider complex of emission from ionized gas is identified as IC1396 and spans 5 degrees of the sky.
