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

Scientists discover a strange new form of ice...
on September 11, 2026 at 6:40 pm
Scientists have discovered that there is ice deep inside planets like Neptune and Uranus and want to find out what form it takes and how it behaves. They cannot dig for it and transport it all the way back to Earth, so they do the next best thing: recreate those extreme conditions in the lab.
JWST discovers that Chariklo's invisible rings...
on September 9, 2026 at 6:00 pm
Until just over a decade ago, ring systems were thought to be exclusive to the giant planets of the solar system, such as Jupiter, Saturn, Uranus and Neptune. However, in 2013, a small body barely 250 kilometers (155 miles) in diameter, located at nearly 17 times the Earth–sun distance, joined this small group. The object is Chariklo, a small body orbiting between Saturn and Uranus, around which astronomers discovered two dense rings.
Giant impacts may strip small icy moons of...

Southwest Research Institute (SwRI) scientists used simulations to understand the role disruptive impacts play on icy moons with subsurface oceans in our solar system. A recent paper published in the journal Nature Astronomy concludes that disruptive impacts can affect the presence and persistence of subsurface oceans in these moons but do not seem to create new oceans.
Hubble and Webb find that far-out solar system...
on September 8, 2026 at 4:05 pm
For the first time, scientists used the combined power of NASA's Hubble and James Webb Space Telescopes to study some of the most far-flung bodies in our solar system, trans-Neptunian objects (TNOs). Some are the smallest and faintest ever directly seen. The researchers unexpectedly found fewer small TNOs than expected and that the colors of these bodies followed the same relationships as those of their larger family members.

Some of the strangest weather in the solar system doesn't happen on Earth or even in Jupiter's Great Red Spot—it happens in the interiors of ice giants like Neptune and Uranus. Specifically, scientists have long believed that, at certain pressures and temperatures, it literally rains diamonds inside these planets. For the first time, scientists have mimicked the process they believe creates this phenomenon.
