As part of the international CLOUD project at the nuclear research center CERN, researchers at PSI have identified so-called sesquiterpenes—gaseous hydrocarbons that are released by plants—as being a ...

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 ...

Penguin poop, also known as guano, is notoriously smelly. But the ammonia in the birds’ excrement does more than just stink—it can play a role in cloud formation over Antarctica. Those clouds affect ...

Star formation unfolds within the cold, dense regions of molecular clouds, vast accumulations of gas and dust that permeate galactic discs. Turbulent motions and magnetic fields within these clouds ...

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 ...

It all begins on the surface of the earth which is in the rivers, in the lakes, in the seas, even in damp soil. When the sun heats water, the water slowly converts to an invisible gas, known as water ...
