Scientists expect that future Webb images of Uranus will reveal the two faint outer rings that were discovered with Hubble during the 2007 ring-plane crossing. Webb also captured many of Uranus’ 27 known moons (most of which are too small and faint to be seen here); the six brightest are identified in the wide-view image.

One day on Uranus is about 17 hours, so the planet’s rotation is relatively quick. This makes it supremely difficult for observatories with a sharp eye like Webb to capture one simple image of the entire planet – storms and other atmospheric features, and the planet’s moons, move visibly within minutes.

This wider view of the Uranian system with Webb’s NIRCam instrument features the planet Uranus as well as six of its 27 known moons (most of which are too small and faint to be seen in this short ...

One day on Uranus takes about 17 hours. And the planet makes a complete orbit around the Sun in about 84 Earth years. Uranus has the third-largest diameter in our Solar System, and is surrounded by 13 faint rings and 27 moons. In visible wavelengths as seen by NASA’s Voyager 2 spacecraft in the 1980s, Uranus appeared as a placid, solid blue ball.

An international team of astronomers used Hubble to make new measurements of Uranus' interior rotation rate by analyzing more than a decade of the telescope’s observations of Uranus’ aurorae. This refinement of the planet’s rotation period achieved a level of accuracy 1000 times greater than previous estimates and serves as a crucial new ...
The moon Miranda is to the upper left of Uranus, and the moon Puck is a faint smudge to the upper right. The bright splotches on Uranus' disk are clouds. New Images Reveal Clouds on Planet Uranus
In that April image, 11 of Uranus’s 13 known rings could be seen, but the final two were too faint to show up. Read more Moons around Uranus may suddenly develop atmospheres in the spring

Astronomers stretched the limit of the ACS to find the S/2003 U 1 and S/1986 U 10. The moons are 40 million times fainter than Uranus. Even with the high resolution and sensitivity of the ACS, astronomers had to overexpose the images of Uranus to pinpoint the moons. The images were made from a series of exposures taken Aug. 25, 2003.
This NASA Hubble Space Telescope image of the planet Uranus reveals the planet's rings, at least five of the inner moons, and bright clouds in the planet's southern hemisphere. Hubble now allows astronomers to revisit the planet at a level of detail not possible since the Voyager 2 spacecraft flew by the planet briefly, nearly a decade ago.
The new image of Uranus from the Webb space telescope makes the 7th planet look as if it’s sparkling in the sunlight. And yet Uranus is located some 1.8 billion miles (2.9 billion km) from our ...
Rings and moons: A Festive display In this latest image, Webb’s exquisite sensitivity not only showcases Uranus’ dim inner and outer rings but also unveils the elusive Zeta ring, the faint and ...
