Uranus : the planet seventh in order from the sun — Merriam-Webster See also OneLook

Encyclopedia

Uranus is the seventh planet from the Sun. Its name is a reference to the Greek god of the sky, Uranus, who, according to Greek mythology, was the great-grandfather of Ares (Mars), grandfather of Zeus (Jupiter) and father of Cronus (Saturn). It has the third-largest planetary radius and fourth-largest planetary mass in the Solar System. Uranus is similar in composition to Neptune, and both have bulk chemical compositions which differ from that of the larger gas giants Jupiter and Saturn. For this reason, scientists often classify Uranus and Neptune as “ice giants” to distinguish them from the other giant planets. — Wikipedia

Science

The NASA/ESA/CSA James Webb Space Telescope has taken a stunning image of the Solar System’s other ice giant, the planet Uranus. The new image features dramatic rings as well as bright features in the planet’s atmosphere. The new Webb data of Uranus offer exquisite sensitivity, revealing the faintest dusty rings. — HubbleWebbESA

History

William Herschel observed Uranus on 13 March 1781 from the garden of his house at 19 New King Street in Bath, Somerset, England (now the Herschel Museum of Astronomy), and initially reported it (on 26 April 1781) as a comet. With a homemade 6.2-inch reflecting telescope, Herschel engaged in a series of observations on the parallax of the fixed stars. — Wikipedia

Uranus and Neptune remain two of the most mysterious objects in the solar system, primarily because they have been visited only by NASA's Voyager 2 spacecraft in 1986 and 1989, respectively. Their "ice giant" moniker comes from longstanding hypotheses that their interiors are comprised of an icy mantle beneath their hydrogen-helium atmospheres. While Jupiter and Saturn are also composed primarily of hydrogen and helium, Uranus and Neptune are hypothesized to have a layered structure composed of […]

Life on Earth took a long evolutionary journey that eventually created us, the purportedly intelligent species that dominates the planet. But there was no grand plan or design, only happenstance, nature and luck. Life on Earth suffered multiple extinctions, but got up, dusted itself off and continued on its long march to complexity.

Saturn's largest moon, Titan, is a unique environment in our solar system. It is the only moon (or body beyond Earth) to have a dense, nitrogen-rich atmosphere, and its methane cycle is very similar to Earth's hydrological cycle, in which solid and liquid methane evaporate to form clouds and return to the surface as precipitation. In addition, its prebiotic surface environment and rich organic chemistry make it a prime destination for astrobiology missions, such as NASA's Dragonfly mission (set […]
