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 ...

Every morning during spring and summer in Mars’s southern hemisphere, a long white cloud appears downwind of the giant ...

A modelling study shows that cloud droplet number and ice formation processes jointly, and often non-linearly, control the ...

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

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

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 ...

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 ...

The Arsia Mons Elongated Cloud as seen by Mars Express. Credit: ESA. Every morning, for several months of the Martian year, something extraordinary happens near one of the tallest ...

Mars Express can capture large stretches of the Martian surface at high resolution. Alongside ESA’s ExoMars Trace Gas Orbiter ...

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 colonies across Antarctica are literally changing the weather—and it’s all about their droppings. New research reveals that ammonia from penguin guano creates massive hotspots of atmospheric ...
