This zoomed-in image of Uranus, captured by Webb’s Near-Infrared Camera (NIRCam) Feb. 6, 2023, reveals stunning views of the planet’s rings. The planet displays a blue hue in this representative-color image, made by combining data from two filters (F140M, F300M) at 1.4 and 3.0 microns, which are shown here as blue and orange, respectively.

The new image features dramatic rings as well as bright features in the planet’s atmosphere. The Webb data demonstrates the observatory’s unprecedented sensitivity for the faintest dusty rings, which have only 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.

When I compare it to the Voyager pics,I think this image contains artefacts.

Maybe those were faked or retouched¡

Great. I had been hoping and hoping that a Webb image of Uranus would be released.

However, it doesn’t look like I expected.

You remember Voyager’s images of Uranus. It was nearly featureless because at the time, Uranus was pole on to the Sun. Remember how Uranus spins on its side.

Well now enough time has passed for Uranus axis to be perpendicular to the Sun.
So Uranus ought to be showing cloud features like Neptune now, not uniform colour.

I had not expected the image from Webb of Uranus to be so blurry, but I like the multiple rings.
