IC 5070 is associated with a nebula known as the “North American Nebula,” a large interstellar cloud of molecules (e.g., hydrogen molecules) and dust. The region of the Pelican nebula draws much research attention because it has a particularly active mix of star-formation associate with an actively evolving gas clouds. The light from young energetic stars is slowly heating cold gas and causing it to ionize along an advancing front. Particularly dense filaments of cold gas are seen to still remain, and among these are found jets emitted from Herbig-Haro objects (e.g., just upper left of the Pelican’s dark silhouette). Herbig-Harlo objects are seen as patches of nebulosity associated with newly born stars, the jets form when narrow jets of gas ejected by those stars collide with nearby clouds of gas and dust at speeds of several hundred kilometers per second.
