A close-up view of the ε ring of Uranus. The ε ring is the brightest and densest part of the Uranian ring system, and is responsible for about two-thirds of the light reflected by the rings. [12] [21] While it is the most eccentric of the Uranian rings, it has negligible orbital inclination. [23]
The normally faint inner and outer rings of Uranus shine in the latest image, including the planet’s closest yet incredibly dim and diffuse Zeta ring. Nine of Uranus’ 27 known moons can also ...
The largest is located twice as far from Uranus as the previously known rings. These new rings are so far from Uranus that they are called the "outer" ring system. Hubble also spotted two small satellites, one of which, Mab, shares its orbit with the outermost newly discovered ring. The new rings bring the total number of Uranian rings to 13. [162]
An artist's impression of Rhea's rings. The density of the particles is exaggerated greatly to aid visibility. [1] Rhea, the second-largest moon of Saturn, may have a tenuous ring system consisting of three narrow, relatively dense bands within a particulate disk. This would be the first discovery of rings around a moon.
Most pictures of Uranus in textbooks show it as a bright blue, featureless ball. But the James Webb Space Telescope, the preeminent new observatory that senses light at invisible, infrared ...
A solar wind event squashed the protective bubble around Uranus just before Voyager 2 flew by the planet in 1986, shifting how astronomers understood the mysterious world.
James Ludlow Elliot (June 17, 1943 – March 3, 2011) was an American astronomer and scientist who, as part of a team, discovered the rings around the planet Uranus. [ 2 ] [ 3 ] Elliot was also part of a team that observed global warming on Triton , the largest moon of Neptune .
Saturn is well known as the planet with rings, but it's hardly the only one. As it turns out, rings around planets aren't all that rare, and at least a few of the planets in our solar system have ...
