Latest Uranus Stories
There are only five bodies in our solar system that are known to bear rings. The most obvious is the planet Saturn; to a lesser extent, rings of gas and dust also encircle Jupiter, Uranus, and Neptune. The fifth member of this haloed group is Chariklo, one of a class of minor planets called centaurs: small, rocky bodies that possess qualities of both asteroids and comets.
Scientists use laser-driving compression experiments (cool) to recreate the planetary formation process (even cooler).
Uranus is typically a tranquil, distant blue world that is barely visible using amateur telescopes, but recent turbulent storms on the planet’s surface have been detected by professionals and amateurs alike.
Our view of other solar systems just got a little more familiar, with the discovery of a planet 25,000 light-years away that resembles our own Uranus.
Astronomers writing in the journal Nature say they have observed a minor planet which contains two rings of ice and pebbles for the first time.
A long-standing mystery surrounding unusual warming of planetary atmospheres is not just exclusive to our solar system, but is most likely universal.
Researchers say that Jupiter and Saturn could contain massive quantities of solid diamonds in their cores.
Researchers, publishing a paper in the journal Nature Communications, say their study on methane's secrets will help scientists better understand the chemistry of planetary interiors.
The first Trojan asteroid sharing the orbit of Uranus has been discovered by University of British Columbia astronomers who believe the asteroid - 2011 QF99 - is part of a larger-than-expected population of transient objects temporarily trapped by the gravitational pull of the solar system's giant planets.
Thirty-six years ago NASA launched one of the longest missions in the space agency's history, the Voyager 2.
Gas Giant -- A gas giant is a generic astronomical term invented by the science fiction writer James Blish to describe any large planet that is not composed mostly of rock or other solid matter. Gas giants may still have a solid core - in fact, it is expected that such a core is probably required for a gas giant to form - but the majority of its mass is in the form of gas (or gas compressed into a liquid state). Unlike rocky planets, gas giants do not have a well-defined surface. There...
Planet Neptune -- Neptune is the eighth planet from the sun. It is a gas giant. Orbiting so far from the sun, Neptune receives very little heat. Its 'surface' temperature is -218 degrees Celsius (below zero). However, the planet seems to have an internal source of heat. It is thought that this may be leftover heat generated by infalling matter during the planet's birth, now slowly radiating away into space. Neptune's atmosphere has the highest wind speeds in the solar system, up to...
Uranus' moon Sycorax -- Sycorax is a moon of Uranus. It was named after a witch living on an island in William Shakespeare's play The Tempest. Its orbital radius is approximately 12.2 million km from Uranus and is about 160 km in diameter, but this size estimate is based on the moon's apparent brightness and the assumption that it has an albedo of about 0.07. Its orbit is retrograde and highly inclined. Sycorax's composition is probably a mixture of rock and ice, and its unusually...
Uranus' moon Caliban -- Caliban is a moon of Uranus, named after Caliban, the character in William Shakespeare's play The Tempest. Caliban was discovered on September 6 - September 7, 1997 by Brett Gladman, Phil Nicholson, Joseph Burns, and JJ Kavelaars using the 200-inch Hale telescope; they also discovered the moon Sycorax at the same time. ----- Discovery Discovered by Brett Gladman Discovered in 1997 Orbital characteristics Semimajor axis 7.1106 km Eccentricity...
Uranus' moon Oberon -- Oberon is the name of the outermost of the major moons of the planet Uranus; discovered on January 11, 1787 by William Herschel. All of the moons of Uranus are named for characters from Shakespeare or Alexander Pope. Names for the first four discovered moons of Uranus (Oberon, Titania, Ariel, Umbriel) were given by John Herschel, the son of William. Oberon was named after Oberon, the king of the Faeries in A Midsummer Night's Dream. Oberon is composed of...
