Share the telescope James Webb NASA’s JWST spacecraft took its first look at the planet Uranus, revealing invisible glowing rings around the ice giant and its twenty-seven moons, and the $10 billion telescope captured 11 of the planet’s 13 rings, which look bright. They seem to blend into a glowing ring.

According to the British newspaper “Daily Mail”, astronomers were surprised by JWST’s strength when Voyager 2 picked up two faint dusty rings that were not discovered until 1986.

The main rings are made of rock several feet across, while the other rings are mainly ice covered by rock.

The rings are thinner, narrower and darker compared to rings found on other planets like Saturn.

Webb also captured several of Uranus’ 27 known moons, most of which are too small and faint to see here, but six were identified as bright in the scene image, and Uranus had a bluish shadow caused by a thick film. Its atmosphere.

The researchers, led by the University of Oxford, named the layer Aerosol-2, which they said was white in visible wavelengths.

The JWST image was made possible by a near-infrared camera (NIRCam), which captures light from the visible edge through the near-infrared band of the electromagnetic spectrum.

A bright cloud at the edge of the polar cap and a second cloud at the southern end are typical of Uranus at infrared wavelengths and may be associated with storm activity.
