Spiral Galaxy M51 (Whirlpool Galaxy) - Hubble Space Telescope Image #3452341 (License: Personal Use)

This high-resolution image reveals the Whirlpool Galaxy (Messier 51), a grand-design spiral interacting with its smaller companion galaxy NGC 5195. Its well-defined spiral arms are rich in young blue star clusters, glowing H II regions, and intricate dust structures, all converging toward a bright, active galactic nucleus. The contrast between warm central hues and cool outer arms highlights ongoing star formation and gravitational dynamics.

Used on astronomy education sites, NASA/Hubble outreach pages, and science blogs to illustrate galaxy morphology, star formation, and telescope imaging capabilities; matches user intent for learning about deep-sky objects or seeking high-quality space imagery.
