NASA’s James Webb Space Telescope (JWST) has uncovered a brand-new moon orbiting Uranus!

At only 6 miles wide, this tiny moon escaped decades of detection. Neither Voyager 2’s historic flyby, the Hubble Space Telescope, nor ground-based observatories were able to spot it. But with JWST’s extraordinary infrared vision, astronomers finally revealed this hidden world. In this video, NASA scientist Stefanie Milam explains how Webb discovered the moon, why it’s so difficult to detect such small objects, and what this means for the future of planetary exploration in our solar system.

🪐 What you’ll learn in this video:

How JWST spotted a moon that Voyager 2 and Hubble missed
Why Uranus’s moons are so challenging to observe
What tiny moons can reveal about the formation of giant planets
How discoveries like this could reshape our understanding of the outer solar system

From discovering new Uranian moons to studying distant galaxies, JWST continues to push the boundaries of astronomy. This latest find shows that even close to home, in our own solar system, there are still hidden worlds waiting to be discovered.
