A Closer Look at the Elephant's Trunk Nebula - IC 1396
The Elephant’s Trunk Nebula (IC 1396) is a giant emission nebula that is over 3 degrees in diameter (Visually, 6 times larger than our full moon). It is illuminated by a hot, massive O-type star (HD 206267) near its center.
The Elephant's Trunk Nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation of Cepheus about 2,400 light years 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 old) stars that were discovered in infrared images in 2003.
The Elephant’s Trunk is over 20 light-years long.
