Sediments from Scotland hint that ocean-atmosphere interactions continued more than 600 million years ago despite widespread ice.

In the oceans and on land, scientists are discovering rare, transitional organisms that bridge the gap between Earth’s simplest cells and today’s complex ones.

The simulations showed that the gravity hole was initially much less pronounced. Between roughly 50 million and 30 million years ago, however, it intensified significantly. This period coincides with ...

About 56 million years ago, Europe and North America began pulling apart to form what became the ever-expanding North Atlantic Ocean. Vast amounts of molten rock from Earth's mantle reached the ocean ...

Researchers at the University of Hawaiʻi have uncovered new clues about how energy moves through the sun's outer atmosphere, using one of nature's rarest events as their window: total solar eclipses.

Fresh evidence from sediment cores, satellite records, and deep-ocean sensors is converging on a troubling finding: meltwater ...

Standing at the rail of a large cruise ship at sunset, the scene can feel simple: metal, water, and sky. Yet the vessel is rarely alone. A cruise ship travels through the ocean as a moving structure ...
