IC 5070 Pelican nebula
Imaged by Jean-Yves Beninger from Ollioules, France on 6 August 2023
The Pelican Nebula is changing.
The entire nebula, officially designated IC 5070, is divided from the larger North America Nebula by a molecular cloud filled with dark dust.
The Pelican, however, is particularly interesting because it is an unusually active mix of star formation and evolving gas clouds.
The featured picture was processed to bring out two main colors, red and blue, with the red dominated by light emitted by interstellar hydrogen.
Ultraviolet light emitted by young energetic stars is slowly transforming cold gas in the nebula to hot gas, with the advancing boundary between the two,
known as an ionization front, visible in bright red across the image center. Particularly dense tentacles of cold gas remain.
