The brightest star in the image is predominantly responsible for lighting up the nebula in this image. Yet we can tell from the image, that it wasn't born here and is in fact a tourist from another constellation. But even that isn't the most important takeaway we can have from the image.
In my opinion, the biggest thought nugget presented here is how the character of hydrogen, in its various states, can change under the influence of the passing star. Understanding these states and their characteristics cascades into a broader, deeper knowledge of many of the dynamic processes that we astrophotographers capture with our cameras - everything from galactic structure amd behaviors and variations to star formation in dark and bright nebula all the way to the death of stars including the planetary nebula and supernova remnants that is left behind.
I am currently on my way to writing a post on how the Flaming Star Nebula reveals these characteristics of low pressure, at APRealSpace.com.
If you are interested in the technical aspects of our astrophotography, the most recent post on the website includes a description on how planetary nebulae form. Check it out and please, send me some feedback.
