Neptune’s mid-latitude clouds began fading in 2019 and have not recovered, according to nearly three decades of observations from the Hubble Space Telescope and ground-based observatories. By 2020, ...

Astronomers have just proposed a solution to the problematic chemical composition of Uranus and Neptune, thus providing clues for understanding their formation. The researchers focused on the ...

Because Uranus and Neptune are so far away, scientists only have educated guesses about the combination of ices and gases that make up these ice giants. While the general understanding is that these ...

The James Webb Space Telescope (JWST) has revealed the sharpest view of Neptune’s rings since the Voyager 2 spacecraft visited the ice giant over 30 years ago. Neptune, the eighth and most distant ...

A team of researchers is challenging our understanding of the Solar System planets interior. The composition of Uranus and Neptune, the two outer most planets, might be more rocky and less icy than ...

Scientists peering at a “warm Neptune” roughly 430 light-years away have discovered far less water in the gassy planet’s atmosphere than they expected — which puts it at odds with the ice giants in ...

New images from the space-based observatory offer a novel view of the planet in infrared. By Jonathan O’Callaghan No spacecraft has visited Neptune since 1989, when the NASA probe Voyager 2 flew past ...

After a difficult search, scientists have found definitive traces of water on a relatively small exoplanet for the first time. The exoplanet in question, HAT-P-11b, is the size of Neptune and has ...

The planets in the Solar System are typically divided into three categories based on their composition: the four terrestrial rocky planets (Mercury, Venus, Earth and Mars), followed by the two gas ...

Because Uranus and Neptune are so far away, scientists only have educated guesses about the combination of ices and gases that make up these ice giants. While the general understanding is that these ...
