Hearty bacteria in a lab survived pressures comparable to an asteroid strike on the red planet, suggesting a hypothetical scenario in which our planet was seeded with life.

The “gravity hole” formed at least 70 million years ago after convection in Earth’s mantle. The weak gravity could impact our ...

Ganymede, Jupiter’s largest moon, produces auroras like Earth’s. New data from Juno reveals surprising details about its magnetic field.

Houchin and his colleagues studied dozens of zircon crystals from the Jack Hills in Western Australia. These are the oldest known fragments of Earth rocks. Some date back to the Hadean Eon, which ...

Here's a thought experiment that keeps planetary scientists awake at night. Strip every living thing from our planet, every bacterium, every blade of grass, every creature that has ever drawn breath ...

Earth’s magnetic field does not simply switch direction like a flipped light switch. It weakens, wanders, and reorganizes ...

Being able to spot the Earth, let alone any signs of life on our planet, would require an enormous telescope from 66 million ...

Earth’s magnetic shield is shifting in dramatic ways. New data from ESA’s Swarm satellites show that the South Atlantic Anomaly — a vast weak spot in Earth’s magnetic field — has grown by nearly half ...

New research shows that the earliest sponges were soft bodied and lacked skeletons, explaining why their oldest fossils are ...

For decades, many scientists believed that most of the water in our planet came from space, transported by meteorites and comets during the first moments of ...

A persistent "gravity hole" beneath Antarctica gives scientists a window into Earth's deep interior, showing how processes far below reshape the planet's gravity field over millions of years.

Scientists identify exoplanet candidate HD 137010 b, a possible Earth-size world orbiting a Sun-like star 146 light-years away ...
