Glowing Views from the Space Station
NASA/Chris Williams 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. Alternatively, it can happen when atoms and molecules that have been ionized by sunlight collide with and capture a free electron.
