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

Voyager Program is an American scientific program that employs two robotic interstellar probes, Voyager 1 and Voyager 2. They were launched in 1977 to take advantage of a favorable alignment of Jupiter and Saturn, to fly near them while collecting data for transmission back to Earth. — Wikipedia

If you've ever taken an introductory astronomy class, you've probably seen the Hertzsprung-Russell (HR) diagram. This graph maps out the life cycle of stars by plotting their temperature against their luminosity, and has been a "cheat sheet" for stellar astrophysics for over a century. But the universe is full of more than just stars, and a new paper in the journal Publications of the Astronomical Society of the Pacific by Gabriel Steward and Matthew Hedman of the University of Idaho, attempts […]

Researchers in the US and Germany have unveiled a theoretical blueprint for an atomic clock driven by a highly synchronized laser, where atoms work in concert rather than independently. Publishing their results in Physical Review Letters, Murray Holland at JILA, University of Colorado, including John Cooper and PhD student Jarrod Reilly, together with Simon Jäger at the University of Bonn revived an idea first proposed in the 1990s—possibly charting a course toward the narrowest-linewidth […]

Astronomers using the W. M. Keck Observatory on Maunakea, Hawaiʻi Island are revealing new insight into the composition and origins of Uranus's two outer rings. Using data from the Keck Observatory Archive (KOA), combined with observations taken by the Hubble Space Telescope (HST) and the James Webb Space Telescope (JWST), researchers constructed the first complete reflectance spectrum (sunlight reflected off the rings) of the μ and ν rings, confirming their colors and uncovering their […]

Planets, like those in our solar system, form in a bottom-up process where small bits of rock and ice clump together and grow larger over time. But the heftier the planet, the harder it is to explain its formation that way.

The interiors of ice giant planets like Uranus and Neptune could be home to a previously unknown state of matter, according to new computational simulations by Carnegie's Cong Liu and Ronald Cohen. Their work, published in Nature Communications, predicts that a quasi-one-dimensional superionic state of carbon hydride exists under the extreme pressures and temperatures found deep inside these outer solar system bodies.
