Uranus Is Luminous

 From Gizmodo:

Though Uranus’ rings were imaged before—by Hubble in November 2014 and November 2022 and by Webb in April, the new, gorgeous image adds some detail. For one, this Webb image—taken by the observatory’s Near-Infrared Camera (NIRCam)—captures the planet’s faint Zeta ring, the ring closest to the planet.

The close-up above shows nine of the planet’s moons. In clockwise order, starting at 2 o’ clock, they are Rosalind, Puck, Belinda, Desdemona, Cressida, Bianca, Portia, Juliet, and Perdita. Uranus’ moons are sometimes called the “literary moons,” NASA’s website states, because they are named for characters in the works of William Shakespeare and Alexander Pope.
