Sprawling
across hundreds of light-years, emission
nebula IC 1396 mixes glowing cosmic gas and
dark dust clouds.
Stars are forming in this area, only about 3,000
light-years
from Earth.
This detailed view
was created in light primarily emitted by
hydrogen gas,
recorded through a
filter
that narrowly transmits a
wavelength characteristic of
glowing hydrogen atoms in the nebula.
Among the intriguing dark shapes within
IC 1396,
the winding Elephant's Trunk nebula lies just left center.
IC 1396 lies in the high and far off constellation
of Cepheus.
