An Elephant's Trunk in Cepheus
Explanation: With image data from telescopes large and small, this close-up features the dusty Elephant's Trunk Nebula. It winds through the emission nebula and young star cluster complex IC 1396 , in the high and far off constellation of Cepheus. Also known as vdB 142, the cosmic elephant's trunk is over 20 light-years long. The colorful view highlights bright, swept-back ridges that outline the region's pockets of cool interstellar dust and gas. Such embedded, dark, tendril-shaped clouds contain the raw material for star formation and hide protostars within . Nearly 3,000 light-years distant, the relatively faint IC 1396 complex covers a large region on the sky, spanning over 5 degrees. This dramatic scene spans a 1 degree wide field, about the size of 2 Full Moons.
