For a long time, scientists assumed that Earth's water was delivered by asteroids and comets billions of years ago. This coincided with the Late Heavy Bombardment (ca. 4.1 to 3.8 billion years ago), a ...

A long-standing idea in planetary science is that water-rich meteorites arriving late in Earth’s history could have delivered ...

Ryugu’s samples reveal that water activity on asteroids lasted far longer than scientists thought, possibly reshaping theories of how Earth gained its oceans. A billion-year-old impact may have melted ...

Our magnetosphere plays the role of gatekeeper, repelling unwanted energy that's harmful to life on Earth, trapping most of it a safe distance from Earth's surface in twin doughnut-shaped zones called ...

Earlier research held that meteorite impacts from the solar system's early days were a major source of Earth's water.

Simulations reveal that Jupiter’s rapid growth disrupted the early solar system, creating rings where new planetesimals formed much later than expected. These late-forming bodies match the ages and ...

Every year, Earth follows a familiar pattern of seasonal changes: As summer rolls around in the Northern Hemisphere, winter creeps in in the Southern Hemisphere, and vice versa. But do other planets ...
