Explanation:
The prominent ridge of emission featured in
this
vivid skyscape is designated IC 5067.
Part of a larger emission region with a distinctive shape, popularly called
The Pelican Nebula, the ridge spans about
10 light-years and follows the curve of the cosmic pelican's head and neck.
Fantastic, dark shapes inhabiting the view are clouds of cool gas and dust
sculpted
by energetic radiation from young, hot, massive stars.
But stars are also forming within the dark shapes.
Twin jets emerging from the tip of the long, dark tendril left of
center are the telltale signs of an embedded protostar cataloged as
Herbig-Haro 555
(HH 555).
In fact, other
Herbig-Haro
objects indicating the presence of protostars are found
within the frame.
The Pelican Nebula itself, also known as IC 5070,
is about 2,000 light-years away.
To find it, look northeast of bright
star Deneb in the high flying
constellation Cygnus.
