The ground beneath our feet is exhaling. Steadily and without pause, through a process called soil respiration, plant roots and microbes release carbon dioxide (CO 2) into the atmosphere. This ...

Alfvén waves are fundamental to the dynamics of space plasmas. New space missions, sophisticated rocket campaigns, and advances in radar networks and computer modeling have grown our understanding of ...

Using a new technique to analyze old synthetic aperture radar data, researchers observed direct evidence of a Venusian lava tube about 300 meters tall and 1 kilometer in diameter. Here an artist’s ...
