A historic astronomical photograph of the Ring Nebula (M57) taken in 1885 by French astronomers Paul and Prosper Henry. The image is rendered in sepia tones on a dark background, showing the nebula as a large glowing oval ring with a darker hollow center and a brighter, diffuse outer halo — the shell of gas expelled by a dying star. Several faint background stars and small fuzzy objects are scattered across the dark field.
