The climate modeling community has been particularly vexed by the glacial/interglacial cycles of the past three million years, when the Northern Hemisphere oscillated between times with and without large ice sheets.
Earth's protective atmosphere has sheltered life for billions of years, creating a haven where evolution produced complex lifeforms like us. The ozone layer plays a critical role in shielding the biosphere from deadly UV ...
In May, powerful solar storms delivered stunning auroras to latitudes that rarely experience them. Light shows were seen as far south as Florida and Texas, while more northerly areas of the United States were treated to spectacular ...
NASA is actively working to return surface samples from Mars in the next few years, which they hope will help us better understand whether ancient life once existed on the red planet's surface billions of years ago. But what ...
The powerful solar storm driving the aurora borealis over global skies last weekend was also triggering the movement of compasses deep in the ocean, as revealed in new scientific findings shared today by Ocean Networks Canada ...
Earth is the only life-supporting planet we know of, so it's tempting to use it as a standard in the search for life elsewhere. But the modern Earth can't serve as a basis for evaluating exoplanets and their potential to ...
Over the last year, our oceans have been hotter than any time ever recorded. Our instrumental record covers the last 150 years. But based on proxy observations, we can say our oceans are now hotter than well before the rise ...
Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have observed a young star designated HD 21997. Results of the new observations indicate that the studied object is a high-frequency Delta Scuti pulsator. ...
It's eclipse season. The sun, Earth and moon are aligned so it's possible for the Earth and moon to cast each other into shadow.
A study led by Prof. Fan Yizhong from the Purple Mountain Observatory of the Chinese Academy of Sciences has achieved significant precision in determining the upper mass limit for non-rotating neutron stars, a pivotal aspect ...
