Researchers discovered a new 'tiny' moon using NASA’s James Webb Space Telescope, the largest, most powerful telescope ever launched into space.

NASA's James Webb Space Telescope has spotted a tiny moon orbiting Uranus, expanding the number of the planet's known satellites to 29.

"It's a small moon but a significant discovery, which is something that even NASA's Voyager 2 spacecraft didn't see during its flyby nearly 40 years ago," she said.
