The Stunning Ring Nebula (M57) - A Cosmic Masterpiece in Deep Space #3248674 (License: Personal Use)

This Hubble Space Telescope image showcases the Ring Nebula (Messier 57), a classic planetary nebula located about 2,300 light-years away in the constellation Lyra. Its expanding shell of ionized gas-primarily hydrogen (red) and doubly ionized oxygen (blue)-forms a glowing torus around the remnant white dwarf at its center. Fine filamentary structures and a faint outer halo hint at complex ejection history and interactions with interstellar medium.

Used in astronomy education, space outreach, and science journalism to illustrate stellar evolution, planetary nebulae formation, and telescope imaging capabilities; matches user intent for learning about deep-sky objects, astrophotography, or cosmic phenomena.
