The exploration of Uranus has, to date, been through telescopes and a lone probe by NASA's Voyager 2 spacecraft, which made its closest approach to Uranus on January 24, 1986. Voyager 2 discovered 10 moons , studied the planet's cold atmosphere , and examined its ring system , discovering two new rings.
The Uranus Orbiter and Probe is an orbiter mission concept to study Uranus and its moons. [1] The orbiter would also deploy an atmospheric probe to characterize Uranus's atmosphere . The concept is being developed as a potential large strategic science mission for NASA .
Three-decade old data may have just led scientists to make a new discovery about Uranus. ... Science & Tech.
Uranus has relatively well developed aurorae, which are seen as bright arcs around both magnetic poles. [111] Unlike Jupiter's, Uranus's aurorae seem to be insignificant for the energy balance of the planetary thermosphere. [114] They, or rather their trihydrogen cations' infrared spectral emissions, have been studied in-depth as of late 2023 ...
A new study from NASA recently announced that four of Uranus’s five biggest moons may have liquid water oceans beneath their surface. The 4 Major Moons of Uranus May Have Underground Oceans ...
Voyager 2's visit to Uranus may have left us with the complete wrong impression of the ice giant for nearly 40 years, according to a new study. Voyager 2 is the only craft to visit Uranus. Its ...
Miranda is the least spherical of Uranus's satellites, with an equatorial diameter 3% wider than its polar diameter. Only water has been detected so far on Miranda's surface, though it has been speculated that methane, ammonia, carbon monoxide or nitrogen may also exist at 3% concentrations.
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.
