Astronaut’s photos from ISS make clouds look otherworldly
NASA astronaut Don Pettit has shared a new series of breathtaking images, this time showcasing clouds in a unique perspective.
These images were taken from the International Space Station (ISS) at an altitude of approximately 250 miles above Earth’s surface. The distinctive appearance of the clouds is a result of the station’s alignment with the day/night shadow of our planet.
“Living in the Twilight Zone,” Pettit wrote on social media. “Our orbit on the space station is currently aligned with Earth’s day-night shadow, allowing us to witness a blend of day and night. This alignment provides ideal conditions for capturing cloud formations under low-angle lighting.”

Living in the Twilight Zone. Our orbit on @Space_Station now is aligned with Earth’s day-night shadow thus we see neither full day nor full night. This is the best time to photograph clouds under low angle lighting. pic.twitter.com/pt7BS9eZwK

Pettit, the oldest serving astronaut at 69 years old, has been captivating his social media audience with a series of stunning images since his arrival at the ISS in September. He has also delighted in sharing his space photography from previous ISS missions.
One of the most remarkable images captured by Pettit during his current mission shows moonlight reflecting off a river in South America, creating a scene he described as “flowing silver snakes.”
He was also able to capture the SpaceX Crew Dragon capsule reentering Earth’s atmosphere at the end of a mission, with his image showcasing a dramatic streak of light as the spacecraft descended at the conclusion of the historic Polaris Dawn mission in September.
In his quest for better images, Pettit developed the “barn door tracker,” a DIY astrophotography tool that allows for sharper images of city lights at night by compensating for the station’s movement in relation to Earth’s surface. This device can also be used for long exposures of the night sky, producing clearer images without star trails by counteracting the rotation of the Earth.
