A new way of measuring structures deep inside Earth has highlighted numerous previously unknown blobs within our planet's mantle. These anomalies are surprisingly similar to sunken chunks of Earth's crust but appear in seemingly impossible places.

Plate tectonics give Earth its mountains, earthquakes, continental drift and maybe even helped give rise to life itself. But do other planets in the solar system have them too?

Earth’s magnetic north is not static. Like an anchorless buoy pushed by ocean waves, the magnetic field is constantly on the move as liquid iron sloshes around in the planet’s outer core.

You may see a round, red moon on the day whose digits, 3/14, look like an approximation of the mathematical constant related to circles, 3.14.

"Once again, the temperature record has been shattered — 2024 was the hottest year since record keeping began in 1880."

A tiny asteroid loitering in a near-Earth orbit for a few months last year may have an intriguing origin on our moon. Its characteristics led scientists to ask: is it a chip off the old lunar block, making a pass by Earth for a visit?

Research co-led by the University of Maryland reveals that drought and increased temperatures in a CO2-rich climate can dramatically alter how grasslands use and move water.

An enormous asteroid potentially larger than the Washington Monument is due to zip past our planet today. The asteroid, named 2022 CE2, is estimated by NASA's Jet Propulsion Laboratory to be about 370 feet across,

Doorbell cameras aren’t just for busting home invaders and porch pirates. A Ring camera captured the sound of a meteorite crash-landing near a house in Prince Edward Island, Canada, marking the first time this interstellar noise had been recorded alongside video footage.

So I grabbed my camera, ran outside, and looked up just as Mars was supposed to emerge from the Moon's curved horizon. Seen with the naked eye, the Moon's brightness far outshined Mars, casting soft shadows on a cold winter evening in East Texas.

This week, uncover some of the oldest ice on Earth, follow a dinosaur highway, learn how Pluto sealed the capture of its moon Charon with a “kiss,” and more.

China has announced plans to build a giant solar power space station, which will be lifted into orbit piece by piece using the nation's brand-new heavy lift rockets.
