We actually know very little about what's going on inside Uranus and Neptune, causing researchers to propose that these ...

What if our understanding of Uranus and Neptune's compositions have been wrong, specifically regarding their classifications ...

Scientists have found that Uranus is emitting its own internal heat — even more than it receives from sunlight — and this discovery contradicts observations of the distant gas giant made by NASA's ...

Scientists have uncovered a long-sought secret hidden deep within Uranus: the icy giant is still radiating internal heat. Contrary to what was believed for decades, Uranus is not merely reflecting ...

For researchers at the University of Idaho, spotting a moon 6 miles wide orbiting Uranus, a staggering 1.8 billion miles from Earth, may actually be easier than finding a white cat in a snowstorm.

Scientists think Uranus’s moon Ariel once had a hidden ocean beneath its icy shell. The moon’s orbit stretched enough to ...

Scientists think one of Uranus' moons may once have had an ocean roughly 100 miles deep — about 40 times deeper than the Pacific Ocean — and could still possibly hold remnants of it.

Uranus’ moon Ariel may look like a frozen, airless world today, but new research suggests that beneath its icy crust, it may once have held an ocean more than 100 miles (170 kilometers) deep. That ...

One of the most notable properties of the giant planets in our solar system—Jupiter, Saturn, Uranus and Neptune—are the ...

Evidence points to a long-lost ocean beneath Ariel’s icy crust. Tides and orbit shifts may have cracked its surface billions of years ago. Growing evidence indicates that a deep ocean may lie hidden ...
