| Description: | This close-up of the neck of the Pelican nebula
centers in HH 555, located in the tip what looks like an elephant's trunk.
Herbig-Haro objects are small-scale shock regions intimately associated with
star-forming regions. At the tip of the trunk is a jet that can barely
be seen, indicating the presence of an unseen protostar. The FOV
is 14.7 x 9.7 arc-min. Southwest is up. |
