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.

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?

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

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.

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?

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.

Ever wanted to see how history connects all around the world? This interactive history map makes it easier than ever.

“We have a strong indication that the uppermost 2,480 meters contain a climate record that goes back to 1.2 million years in a high-resolution record where up to 13,000 years are compressed into one meter of ice,” Julien Westhoff from Copenhagen University said in a press statement.

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.

Three-million-year-old tools found in Kenya reveal early humans' ability to cut food, butcher meat, and adapt to new diets.

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,
