Pinwheel Galaxy (M101) - Infrared View from Spitzer Space Telescope #2223186 (License: Personal Use)

This infrared composite image of Messier 101-also known as the Pinwheel Galaxy-was captured by NASA’s Spitzer Space Telescope, combining data from multiple wavelengths to highlight warm dust (red), older stars (blue), and star-forming regions (pink). Located 21 million light-years away in Ursa Major, M101 spans 170,000 light-years and hosts intense star formation along its well-defined spiral arms. The image reveals intricate filamentary structures and glowing knots where massive stars are born.
