Helix Nebula: The Eye of God in Deep Space | NASA Hubble Image #3062423 (License: Personal Use)

This high-resolution image from the Hubble Space Telescope shows the Helix Nebula (NGC 7293), one of the closest and largest planetary nebulae to Earth, spanning about 2.5 light-years across. Its distinctive eye-like appearance arises from concentric shells of hydrogen (red), oxygen (blue), and nitrogen (green-yellow) emissions, shaped by stellar winds and ultraviolet radiation from the central white dwarf. Fine filamentary structures and cometary knots are visible, offering clues to late-stage stellar evolution.

Used on astronomy education sites, space agency galleries (e.g., NASA, ESA), and science blogs to illustrate planetary nebulae formation, stellar life cycles, or as a featured image for deep-sky observing guides. Matches user intent for visual learning, astrophotography inspiration, or科普 content.
