An unprecedented catalogue of more than 21 000 images taken by a webcam on ESA's Mars Express is proving its worth as a science instrument, providing a global survey of unusual high-altitude cloud ...

Clouds are important for the Earth's energy balance because they interact with radiation in different ways: On one hand, low clouds reflect incoming solar radiation and thus cool the Earth through a ...

Astronomers have observed thick, mineral-rich clouds, potentially containing iron, enveloping the young exoplanet YSES-1b, leading to the possibility of iron rain. The YSES-1 system, only a million ...

Supercooling, a state where liquids don't solidify even below their normal freezing point, still puzzles scientists today. An example of this phenomenon is found everyday in meteorology: clouds in ...

A team of UC San Diego-led atmospheric chemistry researchers moved closer to what is considered the "holy grail" of climate change science when it made the first-ever direct detection of biological ...

NASA scientists have identified an unexpected high-altitude methane ice cloud on Saturn's moon Titan that is similar to exotic clouds found far above Earth's poles. NASA scientists have identified an ...

One of the great puzzles of modern space science is neatly summed up by the view from NASA’s Perseverance, which just landed on Mars: Today it’s a desert planet, and yet the rover is sitting right ...
