NASA shared a stunning image taken from the International Space Station, showing Earth's airglow outlining the planet's horizon with the Moon above. Airglow is caused by atoms and molecules in the upper atmosphere emitting light to shed excess energy. The image, captured on November 14, 2023, also reveals city lights, including Chicago and Denver. NASA explained that studying airglow helps understand the upper atmosphere's temperature, density, and composition, as well as the movement of particles.
