This model reveals how vastly different the atmosphere was on ancient Earth, and how life may have first emerged. The key to unlocking the secrets of distant planets starts right here on Earth.

Billions of years ago, Earth’s atmosphere was hostile, with barely any oxygen and toxic conditions for life. Researchers from the Earth-Life Science Institute studied Japan’s iron-rich hot springs, ...

AFTER THE second world war, Leo Szilard, a pioneering nuclear physicist who had worked on the Manhattan Project, decided to move into biology instead: life; not death. But there was a problem. As a ...

When you think about Earth, you might think of a giant rock, floating around in space, making laps around the sun. A rock that just happens to have critters, plants, and people crawling around its ...

NASA Goddard Space Flight Center (GSFC) and the Universities Space Research Association (USRA) are pleased to announce the popular Earth Science Picture of the Day (EPOD) web site is turning 10. For a ...

Questions about the origin and nature of Earth and the life on it have long preoccupied human thought and the scientific endeavor. Deciphering the planet's history and processes could improve the ...

More than half a billion years ago on a frigid, ice-covered Earth, glaciers stirred up ingredients for complex life by bulldozing land minerals and then depositing them in the ocean, according to a ...

Picture all of Earth’s oceans, which cover about 70% of the planet and are mostly made of hydrogen. Now multiply that by nine. That may be the amount of hydrogen in Earth’s core, possibly making it ...

Earth formed roughly 4.6 billion years ago, and for several hundred million years the planet’s surface was almost certainly too hot and heavily bombarded by comets and asteroids to be hospitable to ...
