The formation of stars is intricately linked to the complex structure and dynamics of molecular clouds—vast, cold, and dense regions in the interstellar medium that primarily consist of molecular ...

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 ...

Marine bacteria carried by warm and moisture-laden atmospheric rivers contribute to the formation of ice clouds at unexpectedly high temperatures in high-latitude regions, research from Japan suggests ...

The teeming life in the Southern Ocean, which encircles Antarctica, contributes to brightening the clouds that form there, according to a new study. The clouds are bright because of their high density ...

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, we ...

Scientists have observed that ammonia in penguin guano is directly related to cloud formation in Antarctica. Gaseous ammonia reacts with gaseous sulfur compounds in the Antarctic atmosphere to form ...

This experiment demonstrates how clouds form in our atmosphere through the interaction of warm and cold air. You'll create a miniature version of this natural process ...
