This nebula, featured on the ‘Astronomy Picture of the Day‘ for this Wednesday (18th), originated from the explosion of a star in the Cygnus constellation about fifteen thousand years ago.
In the image, you can see the western edge of the still-expanding gas cloud, with notable gas filaments such as the Witch’s Broom Nebula and Fleming’s Triangular Wisp, which run diagonally across the photo.
However, what is rarely captured in images but is now visible thanks to a long exposure in various color bands is the vertically extending reflected brown dust on the left side of the image. This dust likely originated in the cooled atmospheres of massive stars.
