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.
What if one mission could study the gravitational ripples triggered by some of the most violent events in the universe — on the way to observing the least-known planets of our solar system?
Here's an observer's guide to the second full moon of October and the other sky sights you can see around it.
Just how many planets are visible without a telescope? Most people will answer "five," but there is a sixth planet that can be glimpsed without visual aid: the planet Uranus.
Researchers are investigating an alien version of water inside the strange, icy interiors of Uranus and Neptune.
If you watched the sun set on Uranus, the sky would start off as a brilliant blue and fade into deeper blues with striking turquoise notes. So how do we know that?
Buried inside data Voyager 2 gathered at Uranus more than 30 years ago is the signature of a massive bubble that may have stolen a blob of the planet's gassy atmosphere.
Just before dawn today (Aug. 21), skywatchers will be able to spot both Uranus and the waning gibbous moon.
Tonight, Aug. 12, Uranus will reverse direction and begin a westward, retrograde loop that will last into mid-January, 2020.
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.
