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.
