Ariel

Astronomers using the James Webb Space Telescope have found that Ariel, a moon of Uranus, has some of the most carbon dioxide-rich deposits in the solar system, hinting at a buried water ocean.

Astronomers have detected the signal of a rainbow-like phenomenon known as the "glory effect" on a planet outside our solar system for the first time.

Astronomers have detected signs of the rainbow-like 'glory effect' in the atmosphere of the ultra-hot Jupiter WASP-76b.

Five of the Uranus moons might be ocean worlds − and if there's water, there might be life.

The moons orbiting Jupiter and Saturn appear to have subsurface oceans — tantalizing targets in the search for life beyond Earth. But it's not clear why these seas exist at all.

ESA's Cheops mission has found LTT9779 b, the shiniest known exoplanet with an 80% reflectivity due to its metallic clouds. This ultra-hot Neptune is a unique entity due to its size and unusually close orbit to its star, prompting further studies to understand its atmosphere and survivability. Da

Recently published findings confirm that the sub-surface ocean of Enceladus contains plenty of phosphorus, the last critical life ingredient scientists had yet to detect on the Saturn...

A new study suggests oceans for 4 Uranus' moons. If true, they'd join a growing number of ocean worlds in the outer part of our solar system. The post Oceans for 4 Uranus' moons likely, astronomers say first appeared on EarthSky.

For the 1st time, astronomers say they have detected a glory on an exoplanet. Glories are a natural phenomenon, but until now seen only on Earth and Venus. The post Rainbow-like glory on an exoplanet is 1st-ever detected first appeared on EarthSky.

Astronomers have discovered three small moons at the farthest planets of our solar system — two circling Neptune and one around Uranus.

The ice giant Uranus and its rings steal the show in this Dec. 18, 2023, image from the James Webb Space Telescope. The telescope captured new images of

The observations are vital for piecing together the science objectives for a future mission to Uranus.

The Republican-controlled House Budget Committee is set to convene a hearing Wednesday to examine legislation that would establish a so-called fiscal commission for the U.S. debt, a proposal that critics have called a Trojan horse for Social Security and Medicare cuts.House Speaker Mike Johnson (R-L...

After capturing the best photos of Neptune in decades in 2022, NASA has pointed the James Webb telescope's high-powered lenses at the solar system's other ice giant, Uranus.

There might be some hidden oceans lurking around Uranus.

Scientists have discovered evidence of oceans on the surface of Uranus' moons, a crucial discovery that hints at life on other planets.

At least one of Uranus's moons may harbor an ocean beneath the surface, adding it to the list of places in the solar system that have a chance of supporting life.

The Uranus system may be even more interesting than we thought.

To find evidence of an ocean inside a small object like Miranda is incredibly surprising, said Tom Nordheim, a planetary scientist at the Johns Hopkins Applied Physics...
