Scientists have confirmed the presence of an immense reservoir of water trapped deep within the Earth’s mantle, reshaping our ...

A new study shows how shifts in ocean iron supply over millions of years impact marine life and carbon dioxide levels.

In Earth’s first few billion years, the planet’s oceans were filled with iron hydroxide, which is an inorganic compound that absorbs blue light.

The most intense warming, which occurred in the North Atlantic, tropical Pacific, South Pacific and North Pacific, accounted for 90% of unexpected oceanic heating during 2023. The North Atlantic MHW ...

New study reveals Earth's oceans were once green due to iron and cyanobacteria. Could sulfur levels turn them purple in the future?

Our new results provide the strongest evidence yet that at least some Halley-type comets carried water with the same isotopic ...

On Earth, water is so intertwined with life that our search for life on other worlds is essentially a search for water. When scientists find exoplanets around distant stars, a primary ...

Blue-green algae, also called cyanobacteria, were one of the earliest life forms on Earth and contributed heavily to the oxygenation of the planet.

"It confirms K2-18 b to be our best chance to study a potential habitable environment beyond the solar system at the present time." ...
