Scientists agree that Earth’s spin has slowed dramatically, but new research suggests the length of a day was much longer for much of Earth’s history

Scientists have discovered a secret tether that keeps planets from colliding into each-other, but that doesnt mean they wont crash into each-other at some point.

A new analysis of chaos in the solar system reveals how planetary collisions are avoided over billions of years.

A new theory explains why our planets avoid collisions for far longer times than standard theories of planetary stability predict.

The centuries-long search to understand our Solar System’s stability could now be over, or maybe not.

For the first time, a physical model consistent with observations successfully describes how the tidal force caused by the gravitational pull of the Moon is slowing down the rotation of our planet and increasing the distance that separates it from the Moon.

Could prehistoric humans have left us evidence of their sophisticated astrological knowledge in the 17,000-year-old Lascaux cave paintings?

Beyond the Solar System, out there in the wider galaxy, a very strange subset of exoplanets exists. Called hot Jupiters, these are majorly clingy – hugging so close to their host stars, theyre not just intensely hot, but also likely warped by gr

“The exoplanet seems to be spiraling away from its star, an unexpected finding given the power of [its sun’s] gravitational pull.”

Researchers have discovered a planet, named WASP-103b, some 1,500 light-years away from Earth, which they say is shaped more like a potato or a rugby ball.
