SH2 106

Imaged by Jean-Yves Beninger from Ollioules, France on 9 August 2023



The prominently vivid red emission nebula captured in the image is known as SH2-106, also referred to as the "Snow Angel."
This formation arises from the interaction of two jets of matter, discharged from a central star, effectively heating the neighboring matter to a temperature of approximately 10,000 °C.
The bluish nebula below is VDB 133, a reflection nebula, reflecting the light of the double star 44 Cygni.
What sets 44 Cygni apart is its significantly whiter light compared to the majority of stars that typically illuminate reflection nebulae. Consequently, the coloration of VDB 133 closely mirrors the hues of the star, instead of the conventional blue associated with a reflection nebula.
