A powerful new observatory has unveiled its first images to the public, showing off what it can do as it gets ready to start its main mission: making a vivid time-lapse video of the night sky that will let astronomers study all the cosmic events that occur over ten years.

“As the saying goes, a picture is worth a thousand words. But a snapshot doesn’t tell the whole story. And what astronomy has given us mostly so far are just snapshots,” says Yusra AlSayyad, a Princeton University researcher who oversees image processing for the Vera C. Rubin Observatory.

“The sky and the world aren’t static,” she points out. “There’s asteroids zipping by, supernovae exploding.”
