NASA'S PICTURE FOR THIS DAY

“An Artificial Comet” is copyrighted by Wang Chao. NASA has permission to show it and we don't, so it isn't on this card.

COSMIC MESSAGE

This image shows a time-lapse sequence of Starlink satellites orbiting Earth, creating an effect similar to a comet's tail. These communications satellites in low Earth orbit reflect sunlight before sunrise. While appearing as points to the eye, long camera exposures turn them into short streaks of light.
