The GRS spectrum is matched by a saturated H2O profile above an opaque water cloud at 5 bars. The pressure of the water cloud constrains Jupiter’s O/H ratio to be at least 1.1 times solar. The NH3 ...

Tuesday evening, if you happened to be looking up, you may have seen some rainbow-esqe clouds high in the sky.

The technical term for this is an iridescence cloud. This happens when sunlight hits tiny ice crystals or water droplets near ...

A new study shows that natural dust particles swirling in from faraway deserts can trigger freezing of clouds in Earth's ...

Fog blankets the south tower of the Golden Gate Bridge in San Francisco on Friday, Oct. 21, 2016. Some scientists want to pursue research into whether marine clouds could be seeded with salt water ...

New observations of a frigid object called WISE 0855, which lies 7.2 light-years from Earth, suggest that the "failed star" has clouds of water, or water ice, in its atmosphere, the researchers said.

Turning clouds into brighter reflective objects could help halt heat-sucking hurricanes from forming, but climate scientists say the risks may outweigh the benefits.

And those massive plumes of particles can "seed" clouds, causing new cloud droplets to form. That's because pollution particles, especially sulfates, are water-soluble, so water droplets cling to ...

The water clouds were discovered on the frigid brown dwarf WISE 0855, which is 7.2 light-years away from Earth.

New observations of a frigid object called WISE 0855, which lies 7.2 light-years from Earth, suggest that the "failed star" has clouds of water, or water ice, in its atmosphere, the researchers said.
