Researchers have developed the Smaller Than Earth Habitability Model (STEHM) to assess which planets can maintain ...

Scientists searching for life beyond Earth have developed a new way to identify which distant planets might be able to ...

A number of hypotheses have been used to explain how free oxygen first accumulated in Earth’s atmosphere some 2.4 billion years ago, but a full understanding has proven elusive. Now a new model offers ...

This model reveals how vastly different the atmosphere was on ancient Earth, and how life may have first emerged. The key to unlocking the secrets of distant planets starts right here on Earth.

Researchers have created a dataset of the whole atmosphere, enabling new research to be conducted on previously difficult-to-study regions. Using a new data-assimilation system called JAGUAR-DAS, ...

Every breath a person takes draws from a gas mixture that has barely shifted in recorded history: roughly 78 percent nitrogen ...
