clouds

Nobel Prize laureate John Clauser has challenged prevailing climate models, which he says have ignored a key variable.

Materials in the thin film on the ocean’s surface may affect ice cloud formation and thus climate on a global scale, especially when other known ice-forming particles like mineral dust are scarce or absent.

Powerful cosmic winds can blow through galaxies, sweeping out interstellar material and stopping future star formation.

To discover what gives clouds above the Southern Ocean their brightness, scientists took a close look at tiny drifting organisms in the sea below.

Take some time to gaze up at some of the most wondrous skies photographed.

Some scientists say the closing of the hole in the ozone layer could accelerate global warming. Does the hole also potentially release pollutants?
