The Elephant's Trunk Nebula in Cepheus
Explanation: Like an illustration in a galactic
Just So Story, the Elephant's Trunk Nebula 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.
This colorful close-up view
was recorded through narrow band filters that transmit the light from ionized hydrogen, sulfur, and oxygen atoms in the region. The resulting composite highlights the bright swept-back ridges that outline 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. The dramatic scene spans a 1 degree wide field, about
the size of 2 Full Moons.
