Featured on August 13, 2021

This infrared view, captured by Spitzer Space Telescope, clearly outlines the spiral arms of Messier 31, the Andromeda Galaxy. The arms are filled with infrared-emitting gas and dust that give birth to new stars. Many newborn stars in the arms are bright and massive, so they help outline a galaxy's spiral arms.
