Clouds need two essential ingredients to form, and both must be present simultaneously for the process to begin. There are two ingredients needed for clouds to form: water and nuclei. The first ...

Antarctica plays a crucial role in Earth's climate system by reflecting solar radiation back into space. The large white ice surfaces and clouds play a decisive role in this process. However, how ...

When a volcano erupts, it can spew ash high into the atmosphere—inserting aerosols right where clouds typically form. How exactly these aerosols impact cloud formation has long been a mystery to ...

Tiny particles bubbling up from melting Arctic sea ice play a key role in cloud formation, suggests new research. The discovery may explain why Arctic clouds behave differently — and lead to improved ...

Clouds form when water vapor — an invisible gas in the atmosphere — sticks to tiny floating particles, such as dust, and turns into liquid water droplets or ice crystals. In a newly published study, ...

Molecular clouds constitute the principal reservoirs of cold, dense gas in the Milky Way, with masses ranging from tens to millions of solar masses. Predominantly composed of molecular hydrogen, they ...
