NASA's Juno mission made a close pass of Jupiter's moon Thebe on May 1, 2026. While about 3,100 miles (5,000 kilometers) away from the moon, the spacecraft snapped this photo using its camera known as the Stellar Reference Unit (SRU). Jupiter has over 100 moons discovered so far and Thebe is the second largest of the planet's inner moons. Those inner moons are all smaller than the gas giant's famously huge Galilean moons — Io , Europa , Ganymede , and Callisto — which orbit farther out. The moon was first discovered in 1980 by NASA's Voyager 1 spacecraft as it flew by Jupiter. Juno launched in 2011 to travel to, orbit around, and study Jupiter. The mission has delivered incredible images and groundbreaking data on the planet and its surrounding moons.…
