Astronomers see 'warm' glow of Uranus's rings

Two telescopes have measured the faint heat from the main, or epsilon ring, of Uranus, enabling astronomers for the first time to determine its temperature: a cool 77 Kelvin.

Look at this colossal storm on Uranus

Unlike the other planets in our solar system, Uranus is tipped on its side. This leaves the sun shining non-stop onto its north pole during its long summer, likely resulting in widespread atmospheric changes.

'Cataclysmic' collision shaped Uranus

Results from computer simulations confirm that young Uranus was involved in a cataclysmic collision with an object twice the mass of Earth.

Two Undiscovered Dark Moons Appear to Be Hiding Near Uranus

After re-examining data acquired by the Voyager 2 spacecraft, astronomers have detected wavy patterns in two of Uranus's dark system of rings' patterns that may be indicative of two undiscovered moons.
