- The image depicts Sh2-82, a small emission nebula in Sagitta about XXXXX light-years away, where a red emission nebula, energized by ultraviolet radiation from young stars, contrasts with a surrounding blue reflection nebula formed by dust scattering stellar light, as detailed in a 2022 astrophotography study by Ron Brecher.

- This nebula's dual structure highlights active star formation, with the red hue dominated by ionized hydrogen (90% of its gas) and the blue from scattered light, supported by spectral analysis from the 1912 work of Vesto Slipher and 1922 findings by Edwin Hubble on nebulae classification.

- Credited to Travis Rector and H. Schweiker, the image leverages advanced imaging from NOIRLab/NSF/AURA, revealing details that challenge earlier assumptions about nebula visibility, aligning with Rector's 2013 research on infrared excess stars.
