Curiosity rover sharpens paradox of ancient Mars (Update)

Mars scientists are wrestling with a problem. Ample evidence says ancient Mars was sometimes wet, with water flowing and pooling on the planet's surface. Yet, the ancient sun was about one-third less warm and climate modelers ...

Research breakthrough could transform clean energy technology

By some estimates, the amount of solar energy reaching the surface of the earth in one year is greater than the sum of all the energy we could ever produce using non-renewable resources. The technology necessary to convert ...

What caused the ice ages? Tiny ocean fossils offer key evidence

The last million years of Earth history have been characterized by frequent "glacial-interglacial cycles," large swings in climate that are linked to the growing and shrinking of massive, continent-spanning ice sheets. These ...

NASA satellites detect pothole on road to higher seas
