A peculiar property of the Earth's magnetic field could help us to work out how our planet was created 4.5 billion years ago, according to a new scientific assessment. There are several theories about ...

"During the early solar system's game of cosmic billiards, Earth was struck by a neighbor,” said Dauphas. “It was a lucky shot. Without the moon's steadying influence on our planet's tilt, the climate ...

It’s one of the most enduring ideas about the formation of our solar system: Earth collided with a Mars-sized object, Theia, and the debris from this cosmic crash eventually became the moon. But a new ...

A new study shows that the so-called planetesimals that accreted together to form Earth must have been composed of dry, rocky materials. Billions of years ago, in the giant disk of dust, gas, and ...

New research has dramatically reshaped our understanding of Earth’s early geological history, overturning traditional beliefs about how the planet’s first continents came into being. Researchers from ...

Tiny crystals of zircon could be geological evidence that the continents were born at meteor impact sites. When you purchase through links on our site, we may earn an affiliate commission. Here’s how ...

New research ultimately poses more questions than it answers. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Scientists have eliminated one ...

Water has made the Earth the planet that it is—a planet known for its blue oceans. Water shapes the land through erosion and is fundamental to Earth’s ability to support life. But we have a hard time ...

A planet called Theia collided with Earth, creating the Moon. Large, dense remnants of Theia exist deep within Earth's mantle. Computer models support the idea that these remnants are from Theia.

Abiotic chemistry in Earth’s atmosphere could have generated biologically important organosulfur molecules as life was ...

There are several theories about how the Earth and the Moon were formed, most involving a giant impact. They vary from a model where the impacting object strikes the newly formed Earth a glancing blow ...
