A new study of the oddest cloud on Mars, which reappears every year at the Arsia Mons volcano, says that "exotic physics" is ...

Learn more about the AMEC, a strange, recurring cloud on Mars that has long baffled scientists, until now.

The physical process likely behind this cloud's formation has never been observed in a planetary atmosphere before.

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 ...

Graduate students analyze cloud formation data with research scientist Jesse Anderson, using the Pi Cloud Chamber to study atmospheric processes. × Michigan Tech's Pi Cloud Chamber is giving ...

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 ...

Scientists have overhauled how the UK Earth System Model simulates polar stratospheric clouds, bringing simulations of the ...

A study led by the EPFL suggests that shipping emissions influence climate-relevant cloud formation and may affect regional climate processes far beyond the polar region. Over the last few decades, ...

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 ...
