These are the top space stories this week from Space.com.
Uranus is the seventh planet from the sun and the third-largest planet in the solar system. The blue-green gas giant has the coldest atmosphere of all the planets in the solar system. Uranus is the only planet in the solar system that orbits the sun on its side, and this extreme tilt is responsible for turning the planet's magnetic fields into a jumbled mess. So far only NASA's Voyager 2 spacecraft has studied the planet up close during a flyby in 1986, but researchers are still studying the planet with telescopes on and around Earth.
Some sort of a heat wave has warmed the rings of Uranus, even though the planet orbits far away from the sun.
It's been decades since a spacecraft visited either Uranus or Neptune — which means scientists are busy dreaming up instruments that could be flown out on the next probe to these ice giants.
No spacecraft has gotten a close look at Uranus in more than three decades — but scientists know they want to go back, if they can design the right mission to do so.
If you don't like your local weather, perhaps you would prefer the atmosphere on Uranus or Neptune — and the Hubble Space Telescope has an update on each planet's current conditions.
Solar systems are messy places, but the tools astronomers use to understand these systems can re-create that chaos with surprising beauty.
Uranus reached opposition on Oct. 23, and if you want to observe the frigid planet this week, look toward the full moon.
The full moon of October, called the Hunter's Moon, will grace the skies Oct. 24, making a close pass by Uranus.
Why settle for a planet or two when you can catch all of them in just one night of intense skywatching?
For the first time, researchers re-created the high-pressure water ice likely found in the interiors of Uranus and Neptune.
The clouds in Uranus' upper atmosphere are composed largely of hydrogen sulfide, the molecule that makes rotten eggs so stinky, a new study suggests.
The solar system's outer planets — Jupiter, Saturn, Uranus and Neptune — are mainly giant balls of gas much larger than Earth.
NASA's Planetary Science Division Director, Jim Green, talks to NASA Goddard's Amy Simon, who studies the outer planets Uranus and Neptune.
Uranus has 27 known moons discovered through telescopes as well as the Voyager 2 mission to the planet in 1986.
The giant impact from an Earth-size rock that knocked Uranus sideways may have also helped create the tilted planet's moons, a new study finds.
