Explanation: The prominent ridge of emission featured in this vivid skyscape
[5]  is designated IC 5067. Part of a larger emission region with a
distinctive shape, popularly called The Pelican Nebula [6] , 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 [7]  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 [8] ). In fact [9] , other
Herbig-Haro objects [10]  indicating the presence of protostars are found
within the frame [11] . The Pelican Nebula itself, also known as IC 5070, is
about 2,000 light-years away. To find [12]  it, look northeast of bright star
Deneb [13]  in the high flying constellation Cygnus.
