NASA astronaut Chris Williams photographed the Milky Way rising above Earth's atmospheric glow, known as airglow, from the International Space Station. The image was taken on April 13, 2026, from a docked SpaceX Dragon capsule. Airglow is a natural phenomenon caused by atoms and molecules in the upper atmosphere releasing light after being excited by sunlight.
Facts First
- NASA astronaut Chris Williams captured an image of the Milky Way rising above Earth's atmospheric glow on April 13, 2026.
- The photograph was taken from a SpaceX Dragon capsule docked to the International Space Station (ISS).
- The atmospheric glow, called airglow, occurs when atoms and molecules in the upper atmosphere emit light after being excited by sunlight.
- Airglow is energized by ordinary, day-to-day solar radiation, unlike auroras which are driven by high-energy particles from the solar wind.
What Happened
NASA astronaut Chris Williams captured a photograph of the Milky Way galaxy rising above Earth's atmospheric glow, known as airglow, on April 13, 2026. Williams took the image while aboard a SpaceX Dragon capsule that was docked to the International Space Station (ISS).
Why this Matters to You
This image provides a unique perspective on a subtle, ever-present phenomenon in our planet's atmosphere. While airglow is typically too faint to see clearly from the ground, it is a constant process driven by the sun's everyday light, reminding you of the dynamic and interconnected nature of Earth's systems that exist just beyond ordinary sight.
What's Next
Images like this may continue to be captured by astronauts on the ISS, offering further documentation of Earth's atmospheric phenomena from space. Such photography helps illustrate the differences between common atmospheric glows and more dramatic events like auroras for public education and scientific communication.
