Description:
The Elephant's Trunk nebula is a concentration of interstellar gas and dust in
the star cluster IC 1396 and ionized gas region located in the constellation
Cepheus about 2,400 light years away from Earth. The piece of the nebula shown
here is the dark, dense globule IC 1396A; it is commonly called the Elephant
Trunk nebula because of its appearance at visible wavelengths, where it is a
dark patch with a bright, sinuous rim. The bright rim is the surface of the
dense cloud that is being illuminated and ionized by a very bright, massive star
that is just to the west of IC 1396A. (In the Figure above, the massive star is
just to the left of the edge of the image.) The entire IC 1396 region is ionized
by the massive star, except for dense globules that can protect themselves from
the star's harsh ultraviolet rays. (Wikipedia)
