Astronomers have been exploring Uranus since its discovery in 1781. The first detailed observations of the planet were made by the Voyager 2 spacecraft during its flyby in 1986, which provided us with the most comprehensive data about Uranus to date.
Since then, astronomers have continued to study Uranus using various telescopes and observatories such as the Hubble Space Telescope. In recent years, advances in technology have enabled astronomers to observe Uranus in greater detail than ever before, allowing them to study its atmosphere, magnetic field, and moons in more detail.
Uranus also has rings
The rings of Uranus were discovered in 1977 when the planet passed in front of a star, and its light was momentarily blocked by the presence of the rings. Like the rings of Saturn, the rings of Uranus are made up of millions of small particles of ice and rock, ranging in size from tiny grains to large boulders.
The exact origins of the rings of Uranus are not entirely clear, but there are several theories about how they were formed. One theory suggests that the rings are the remnants of a moon or moons that were destroyed by a collision with a comet or asteroid. Another theory proposes that the rings were formed from debris left over from the formation of Uranus and its moons, which were then captured by the planet’s gravity.
The James Webb Space Telescope has taken new images of Uranus. All of the planet’s rings can be seen:
Uranus has never looked better. Really.
Only Voyager 2 and Keck (with adaptive optics) have imaged the planet's faintest rings before, and never as clearly as Webb’s first glimpse at this ice giant, which also highlights bright atmospheric features. https://t.co/aE3rJIqVKy pic.twitter.com/RZElIRkudl

The rings of Uranus are unique in that they are not very bright and are composed primarily of dark material, which makes them difficult to observe. However, they have been studied in detail by the Voyager 2 spacecraft and other telescopes. The rings are divided into several distinct groups, and the largest and brightest of these is called the epsilon ring.
