James Webb takes the first picture of the ice giant Uranus and its 27 moons
A picture of the planet and the moons that orbit it
The giant space telescope "James Webb" captured pictures of the ice giant that show for the first time the invisible rings of the planet and the 27 moons that orbit it.
The $10 billion telescope managed to capture 11 of the 13 rings of Uranus, which appeared so bright that they seemed to blend into one bright ring.
The telescope also amazed astronomers by taking pictures of the two highest dusty rings that were not discovered until 1986 during the Voyager 2 space shuttle flight.
The main rings of the planet are composed of icy boulders several feet across, while the other rings are mainly composed of icy masses darkened by rock.
The rings are thin, narrow, and dark compared to those of other planets, such as Saturn.
The Webb telescope also captured many of the 27 known moons of Uranus, most of which are too small and dim to be seen accurately, but six bright moons were identified in one image that was displayed for only 12 minutes.
Information about the planet
The ring system of Uranus is the second ring system discovered in the solar system. Scientists believe that these rings are of relatively recent origin and did not arise with its inception. Most likely they were formed from materials and particles that resulted from the destruction of the planet's moons.
Uranus a 27 lunes qui ont été nommées d'après les travaux de certains écrivains tels que William Shakespeare et Alexander Pope. La masse de ces lunes est très petite par rapport à la masse du reste des lunes des planètes gazeuses, comme la masse de la La lune de Neptune est deux fois plus massive que les cinq principales lunes d'Uranus réunies.Ces lunes sont constituées principalement de glace et de roche en proportions égales.
Elle est considérée comme la troisième planète en termes de magnitude et de taille après Jupiter et Saturne, et sa méthode de rotation et son axe diffèrent du reste de la planète, en raison de la forte inclinaison de son axe, de sorte que ses pôles sont situés à la place du équateur de la plupart des planètes du système solaire. Uranus peut être vu dans le ciel terrestre à l'œil nu, comme Vénus et Mars.
