North America and the Pelican
Explanation: Fans of our fair planet might recognize the outlines of these
cosmic clouds. On the left, bright emission outlined by dark, obscuring dust lanes seems to trace a continental shape, lending the popular name
North America Nebula to the emission region cataloged as NGC 7000. To the right, just off the North America Nebula's east coast, is IC 5070, whose profile suggests the
Pelican Nebula. The two bright nebulae are about 1,500 light-years away, part of the same
large and complex star forming region, almost as nearby as the better-known Orion Nebula. At that distance, the 6 degree wide field of view would span 150 light-years.
This careful cosmic portrait uses
narrow band images to highlight the bright
ionization fronts and the characteristic red glow from atomic hydrogen gas.
These nebulae can be seen with binoculars from a dark location.
Look northeast of bright star Deneb in the constellation of Cygnus the Swan.
