Two additional rings were discovered in 1986 in images taken by the Voyager 2 spacecraft, and two outer rings were found in 2003–2005 in Hubble Space Telescope photos. In the order of increasing distance from the planet the 13 known rings are designated 1986U2R/ζ, 6, 5, 4, α, β, η, γ, δ, λ, ε, ν and μ.
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 ...
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] In April 2006, images of the new rings from the Keck Observatory yielded ...
For this reason, scientists often classify Uranus and Neptune as "ice giants" to distinguish them from the gas giants. Uranus's atmosphere is similar to Jupiter's and Saturn's in its primary composition of hydrogen and helium, but it contains more "ices" such as water, ammonia, and methane, along with traces of other hydrocarbons.
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 ...
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 ...
The International Mineralogical Association (IMA) is the international scientific group that recognises new minerals and new mineral names. However, minerals discovered before 1959 did not go through the official naming procedure. Some minerals published previously have been either confirmed or discredited since that date.
