Description:
A close up view of the head and neck region of the Pelican Nebula in Cygnus (IC 5070). The image is a hybrid image of hydrogen-alpha and RGB data. It shows extensive nebulosity silhouetting a vast network of forking wisps and globules of dark dust. The bright region at upper right along the bak of the Pelican's neck is a shock front caused by intrusion of a separate hydrogen cloud, IC 5067. The long elephant trunk extending in front of the neck can be seen to have 2 delicate tendrils extending in opposite directions from its tip. This is material being ejected from opposite poles of a newborn star within the tip of the trunk and is known as Herbig-Haro 555. This is a re-processed version to show more more nebular detail and star colors.
