Good morning, my friend Maj William W. 'Bill' Price and thank you for posting the NASA Astronomy Picture of the Day (APOD) for Wednesday, September 25, 2019 entitled "The Pelican Nebula in Gas, Dust, and Stars."

Beautiful picture - to be honest I prefer these magnificent images of the heavens than the composite pictures which though interesting seem to be more artistic talent than astronomy image.
"Explanation: The Pelican Nebula is slowly being transformed. IC 5070, the official designation, is divided from the larger North America Nebula by a molecular cloud filled with dark dust. The Pelican, however, receives much study because it is a particularly active mix of star formation and evolving gas clouds. The featured picture was produced in three specific colors -- light emitted by sulfur, hydrogen, and oxygen -- that can help us to better understand these interactions. The light from young energetic stars is slowly transforming the cold gas to hot gas, with the advancing boundary between the two, known as an ionization front, visible in bright orange on the right. Particularly dense tentacles of cold gas remain. Millions of years from now this nebula might no longer be known as the Pelican, as the balance and placement of stars and gas will surely leave something that appears completely different.
Thank you, my friend Maj Marty Hogan for mentioning me.
