What if Earth’s core cooled down completely?
Beneath the Earth’s surface lies the core, a scorching sphere of iron surrounded by a layer of molten metal. Temperatures at the core reach approximately 6,000°C (10,800°F), comparable to the surface ...
Thousands of satellites that disintegrate upon re-entry release aluminum into the atmosphere, disrupting polar winds and the ...
New satellite-based analysis explains how energy carried by Alfvén waves moves from Earth’s magnetosphere into the atmosphere to generate auroral light emissions.
Tiny marine plankton that build calcium carbonate shells play an outsized role in regulating Earth’s climate, quietly pulling carbon from the atmosphere and helping lock it away in the deep ocean. New ...
Oxygen is everywhere on Earth today. But that hasn’t always been the case. Scientists think oxygen only became a lasting part ...
New research reveals the source of this carbon – and the driving forces behind it – are far more complex than previously thought.
NASA selects STRIVE and EDGE missions to advance Earth science research, improve atmospheric and ecosystem monitoring, and support environmental and safety planning.
Scientists at the University of Southampton have uncovered evidence from ancient rocks that Earth's climate continued to ...

Climate ‘fingerprints’ mark human activity from the top of the atmosphere to the bottom of the ocean
The ocean is warming as the upper atmosphere is cooling – both as a result of excessive greenhouse gas emissions.
