The seventh world from the Sun, Uranus is special: It turns on its side, at roughly a 90-degree angle from the plane of its orbit. This causes severe seasons given that the planets poles experience several years of consistent sunlight followed by an equal number of years of total darkness. (Uranus takes 84 years to orbit the Sun.) Currently, it is late spring for the northern pole, which is visible here; Uranus northern summer will be in 2028. On the other hand, when Voyager 2 visited Uranus it was summertime at the south pole. The south pole is now on the dark side of the planet, out of view and facing the darkness of area.
This zoomed-in picture of Uranus, caught by Webbs Near-Infrared Camera (NIRCam) on February 6, 2023, exposes sensational views of the planets rings. On the best side of the planet, theres an area of brightening at the pole facing the Sun, called a polar cap. This polar cap is unique to Uranus because it is the only world in the planetary system tilted on its side, which causes its severe seasons. A new aspect of the polar cap exposed by Webb is a subtle brightening near the Uranian north pole. At the edge of the polar cap lies an intense cloud in addition to a few fainter prolonged features simply northward of the caps edge, and a second very bright cloud is seen at the planets left limb. Such clouds are common for Uranus in infrared wavelengths, and likely are connected to storm activity. Credit: Science: NASA, ESA, CSA, STScI, Image Processing: Joseph DePasquale (STScI).
This infrared image from Webbs Near-Infrared Camera (NIRCam) combines data from two filters at 1.4 and 3.0 microns, which are shown here in orange and blue, respectively. The planet displays a blue color in the resulting representative-color image.
When Voyager 2 took a look at Uranus, its electronic camera showed a practically featureless blue-green ball in noticeable wavelengths. With the infrared wavelengths and additional sensitivity of Webb we see more detail, showing how vibrant the environment of Uranus actually is.
This larger view of the Uranian system with Webbs NIRCam instrument includes the planet Uranus as well as 6 of its 27 known moons (many of which are faint and too small to be seen in this short exposure). A handful of background objects, including many galaxies, are also seen. Credit: Science: NASA, ESA, CSA, STScI, Image Processing: Joseph DePasquale (STScI).
On the best side of the planet, theres a location of brightening at the pole dealing with the Sun, known as a polar cap. The sensitivity and longer wavelengths of Webbs NIRCam may be why we can see this boosted Uranus polar function when it has not been seen as clearly with other effective telescopes like the Hubble Space Telescope and Keck Observatory.
At the edge of the polar cap lies an intense cloud along with a couple of fainter prolonged features simply beyond the caps edge, and a 2nd extremely bright cloud is seen at the planets left limb. Such clouds are typical for Uranus in infrared wavelengths, and likely are connected to storm activity.
This planet is defined as an ice giant due to the chemical cosmetics of its interior. Most of its mass is thought to be a hot, dense fluid of “icy” materials– methane, water, and ammonia– above a little rocky core.
The James Webb Space Telescope has taken a spectacular image of the Solar Systems other ice giant, the world Uranus. The new image features remarkable rings as well as intense features in the planets environment. The seventh world from the Sun, Uranus is odd: it turns on its side, at an almost 90-degree angle from the airplane of its orbit.
9 are classified as the primary rings of the world, and 2 are the fainter dirty rings (such as the diffuse zeta ring closest to the planet) that werent found up until the 1986 flyby by Voyager 2. Scientists expect that future Webb images of Uranus will reveal the two faint outer rings that were discovered with Hubble throughout the 2007 ring-plane crossing.
Webb likewise caught numerous of Uranuss 27 known moons (many of which are too little and faint to be seen here); the six brightest are determined in the wide-view image. Extra research studies of Uranus are happening now, and more are planned in Webbs first year of science operations.
In 2022, the National Academies of Sciences, Engineering, and Medicine identified Uranus science as a priority in its 2023-2033 Planetary Science and Astrobiology decadal survey.
The James Webb Space Telescope is the foremost area science observatory in the world. It will unwind the tricks of our planetary system, explore distant planets around other stars, and examine the enigmatic structures and starts of the universe and our position within it. The program is a collaboration in between NASA, the European Space Agency (ESA), and the Canadian Space Agency, and is led by NASA.
Following in the steps of the Neptune image released in 2022, NASAs James Webb Space Telescope has taken a spectacular image of the solar systems other ice giant, the planet Uranus. The seventh world from the Sun, Uranus is special: It turns on its side, at approximately a 90-degree angle from the aircraft of its orbit. The James Webb Space Telescope has actually taken a sensational image of the Solar Systems other ice giant, the world Uranus. The seventh planet from the Sun, Uranus is strange: it rotates on its side, at an almost 90-degree angle from the aircraft of its orbit. 9 are classified as the main rings of the world, and 2 are the fainter dusty rings (such as the diffuse zeta ring closest to the planet) that werent found till the 1986 flyby by Voyager 2.

Webbs Infrared Image Highlights the Planets Dramatic Rings and Dynamic Atmosphere.
The planet Uranus is an oddball in our solar system, slanted on its side as it orbits the sun, causing severe seasons. While the planets environment appeared nearly featureless when visited by the Voyager 2 spacecraft in 1986, subsequent observations from the ground and in area have actually shown unstable storms.
NASAs James Webb Space Telescope just recently observed Uranus, and the resulting image highlights a complex system of rings in addition to a bright polar cap and likely storm clouds.

The planet shows a blue hue in this representative-color image, made by combining information from two filters (F140M, F300M) at 1.4 and 3.0 microns, which are revealed here as blue and orange, respectively.

Webb Space Telescope Scores Another Ringed World with New Image of Uranus.
Following in the steps of the Neptune image released in 2022, NASAs James Webb Space Telescope has taken a spectacular image of the solar systems other ice giant, the planet Uranus. The new image features dramatic rings as well as intense features in the worlds environment. The Webb information shows the observatorys unprecedented level of sensitivity for the faintest dusty rings, which have just ever been imaged by two other facilities: the Voyager 2 spacecraft as it flew past the planet in 1986, and the Keck Observatory with advanced adaptive optics.
