The Milky Way
NASA astronaut Chris Williams captured the Milky Way rising above Earth’s atmospheric glow on April 13, 2026, while aboard a SpaceX Dragon docked to the International Space Station. This atmospheric glow is also called airglow. It occurs when atoms and molecules in the upper atmosphere, excited by sunlight, emit light to shed their excess energy.
