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

Ariel, one of Uranus' icy moons, may once have concealed a vast ocean more than 100 miles (170 kilometers) deep beneath its ...

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 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.

A new paper suggests that Uranus might still contain evidence of the catastrophic impact that knocked it on to its side and shaped much of its evolutionary history. If it's accurate, there are some ...

It's been almost 40 years since Voyager 2 flew past Uranus, but its readings from that whistlestop flyby have remained some of the most important for how we understand the planet. But new data from a ...

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 ...
