Uranus has weird rings. Astronomers now know the source of two of them

A new study suggests one ring comes from the moon Mab and the other from unseen rocky bodies

Uranus appears as a pale blue disk encircled by several faint, bright rings.

In 2023, the James Webb Space Telescope caught sight of Uranus and its gossamer ring system, glowing in infrared. Several of its moons can also be seen pirouetting around the ice giant in this false color image.

The rings around Uranus have mystified astronomers for almost half a century.
