A team led by an astronomer from the University of Kansas has crunched data from NASA’s TESS and Spitzer space telescopes to portray for the first time the atmosphere of a highly unusual kind of ...

We might have been very wrong about exactly what lurks below the tranquil blue and green surfaces of Uranus and Neptune. Previous theories have suggested a range of hidden properties of the two ...

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

New NASA Hubble Space Telescope images of the distant planet Neptune show a dynamic atmosphere and capture the fleeting orbits of its satellites. The images have been assembled into a time-lapse movie ...

CAPE CANAVERAL, Florida (KRON) — NASA has confirmed its Hubble Space Telescope caught the presence of a dark vortex in the atmosphere of Neptune. The full visible-light image shows that the dark ...

Blasting around the equators of the solar system's giant planets - Jupiter, Saturn, Uranus and Neptune - are fierce jet ...

There aren't a lot of Hot Neptunes in the galaxy, and it's not entirely clear why. A Hot Neptune is, as the name implies, a Neptune-sized planet orbiting within 1 AU of its host star. While we've ...

Researchers observed exoplanet GJ 1214b's atmosphere by measuring the heat it emits while orbiting its host star. Astronomers directly detected the light emitted by a sub-Neptune exoplanet -- a ...

At the left, an enhanced-color image of Neptune from the NASA/ESA Hubble Space Telescope. At the right, that image is combined with data from the NASA/ESA/CSA James Webb Space Telescope. The cyan ...

NASA's James Webb Space Telescope has peeled back the layers on sub-Neptunes, a type of gassy exoplanet scattered in large numbers throughout the universe. While sub-Neptunes' thick atmospheres have ...
