Earth’s magnetic field, the invisible barrier that deflects solar radiation and makes surface life possible, is not permanent in its current orientation. Geologic records show that magnetic north and ...

Satellite-based Earth observation provides a unique and powerful tool in tracking climate adaptation, an international study involving University of Galway researchers has shown. An international ...

Earth’s oxygen-rich atmosphere, the very thing that allows complex life to exist, may not last forever. Coupled biogeochemistry and climate simulations estimate that the planet’s breathable air could ...

NASA is planning a mission to demonstrate the ability to repair and upgrade satellites in Earth orbit. The mission, called OSAM-1 (On-orbit Servicing, Assembly, and Manufacturing-1), will send a ...

Earth has experienced several climate cycles throughout its long history, including several ice ages that caused the planet to freeze over. The last ice age occurred approximately 11,700 years ago, ...

For now, life thrives on our oxygen-rich planet. But Earth's atmosphere won't always be so welcoming. In fact, scientists predict that Earth will eventually undergo a drastic atmospheric shift—one ...
