Pillars of gas, dust, and young, hot stars seem to
fill the gaping maw of NGC 7822.
At the edge of a giant
molecular cloud toward the northern
Cepheus, the glowing star forming region
lies about 3,000 light-years away.
Within the nebula, bright edges and dark shapes are
highlighted in this
The image includes data from both broadband and
mapping emission from atomic oxygen, hydrogen, and sulfur into blue,
green, and red hues.
The atomic emission is
powered by the energetic radiation from
the hot stars, whose powerful winds and radiation also sculpt
and erode the denser pillar shapes.
Stars could still be forming
inside the pillars by
but as the pillars are
eroded away, any forming stars will ultimately be cutoff from their
This field spans around 60 light-years at the estimated distance
of NGC 7822.
