When the early Earth’s magma ocean crystallized 4.4 billion years ago, the deep mantle trapped an ocean’s worth of water, ...

Today, oceans cover about 70% of Earth’s surface. This stark contrast has long driven scientific interest in how water ...

Earth should have lost its water long before life ever had a chance to appear. Bathed in a young Sun’s fierce radiation and wrapped in a global magma ocean, the planet’s surface looked more like a ...

Earth’s distant future has always been framed as a slow fade billions of years from now, but a new generation of models is ...

Earth's deep mantle stored enough water in rocks to equal one ocean during our planet's early molten days, helping explain ...

One key component might be RNA, a molecular cousin of DNA found in every form of life on Earth, and now scientists say they ...

Earth’s deep interior still shapes the world above your feet. Water trapped far below the surface helps control how rocks ...

Four billion years ago, our then stripling sun radiated only 70 to 75 percent as much energy as it does today. Other things on Earth being equal, with so little energy reaching the planet’s surface, ...

IMAGE: A new study by CU-Boulder researchers indicates a thick organic haze shrouding Earth several billion years ago was similar to the one now hovering over Saturn’s largest moon, Titan. University ...

Four billion years ago, Earth was violent, hot, and unstable. Yet new research suggests that by then, life had already ...
