Ancient South African rocks expose the chain reaction behind life’s first real growth spurt.

When Earth formed billions of years ago, its metallic core was wrapped in a global ocean of molten rock, which eventually cooled and crystallized to form the mantle. Today, when deep-rooted mantle plumes rise toward the surface and produce volcanic eruptions,

Scientists believe there are planets outside our solar system where life is even more abundant and sustainable.

Earth’s center of mass is constantly on the move, shifting by a few millimeters as enormous amounts of water, ice, and even air migrate around the planet with the seasons. NASA scientists have developed a more precise way to track these tiny swings using laser-ranging satellites,

“This is an exciting finding,” Richard Gordon said of his research with his former student Daniel Woodworth

Still, the study's authors say there is hope for solutions despite record-setting heat and historic storms.

An astronaut floats above Earth during a spacewalk. Remarkably, more people have ventured outside spacecraft than there are surviving members of some of the world’s most endangered species, a crisis Jeff Bezos’s Earth Fund and eight other organizations hope to address.

Climate change has pushed the planet's environmental systems "deeper into uncharted territory," researchers said in a new report centered on the state of Earth's climate in 2026.
