A new NASA study shows that dust rising above the world's deserts causes a more significant localized warming effect than previously thought.

Scientists are challenging the idea that the oxygenation of the oceans and atmosphere of Earth occurred only in a positive direction starting 2.4 billion years ago. Their study shows evidence of a drop in oxygen after it first began to rise.

The Earth has vast oceans and large glaciers near its poles, yet less than one percent of our planet's mass is locked up in water. A new analysis is helping astronomers understand why the Earth is comparatively dry.

The astrobiology community mourns the death of Dick Holland, treasured colleague and forefather of astrobiology.

A new study shows that the formation of most minerals containing mercury could be linked to episodes of supercontinent assembly over the last 3 billion years.

A new study shows that soil plays an important role in controlling the Earth's atmospheric future. The results are shedding new light on how ecosystems respond to rising levels of carbon dioxide.

From the vantage of the International Space Station, astronauts are conducting studies that are providing valuable data about the conditions deep inside Earth.

The ground beneath our feet may have more influence on the air than previously thought. A new study links the oxygenation of Earth's atmosphere to a sudden change in the inner workings of our planet.

A new discovery may help answer the question, is the planet Earth really a giant 'living organism.' The research focuses on interactions between ocean organisms, atmosphere and land.

Uma nova descoberta pode ajudar a responder a questão, será o planeta Terra realmente um “organismo vivo” gigante? A pesquisa foca nas interações entre organismos oceânicos, a atmosfera e terra.
