A white and pink spiral galaxy.
Text, VISIBLE LIGHT. By observing infrared light, we notice details of galaxies we would otherwise miss. INFRARED LIGHT.
The galaxy in infrared is green and white with large pink gas clouds.
Text, Hubble Image, Spiral Galaxy M101. VISIBLE LIGHT. Spitzer Image, Spiral Galaxy M101. INFRARED LIGHT. In visible light, bright stars dominate the view. In infrared light, warm dust and gas clouds are more prominent.
Some objects, like cooler stars, also glow more brightly in infrared light than in visible light, and we need to detect infrared light to study them.
