Explore how gravity changes across planets, ending with a powerful look at the Sun's extreme gravitational force ...

A team of scientists led by expert Raúl Jiménez, ICREA researcher at the University of Barcelona's Institute of Cosmos ...

Have you ever wondered why all the planets in our solar system orbit in the same plane? This fascinating characteristic of planetary orbits has intrigued astronomers for centuries. When we observe the ...

Gravity is an energy wave, just like everything else. It has a wave length of 50 billion to 5 trillion light years. It has properties of wave and "particle", although we all know there are no ...

Anyway, the planets are round because of gravity. Billions of years ago, when the universe was just starting out, there were innumerable bits of gas and dust floating around out there.

Two small planets might be sculpting an enormous dust ring around the star Fomalhaut, a mere 25 light-years away from Earth. But it’s not too likely that either planet is the notorious Fomalhaut ...

An international team of astrophysicists has devised a way to measure the surface gravity of distant stars to help determine if the planets in their orbit are hospitable to life.

A young sunlike star called HOPS 315 seems to host a swirling disk of gas giving rise to minerals that kick-start the planet formation process.

Here on Earth, we’ve solved the challenge of getting ourselves into space thanks to the happy fact that chemical propulsion is sufficient for producing the speeds required to leave our planet ...

Stars often whip their planets with solar winds and radiation, pull them ever closer with gravity and sear them with heat.
