MIT astronomers estimate a planet 140 light-years from Earth may disintegrate fully within the next 1 to 2 million years.

Brian Cox: Gravity is the force that keeps our feet firmly rooted to our planet. Yet although it may appear constant and unchanging, this force varies on all the planets in the solar system and on ...

Have you ever wondered why all the planets in our solar system– whether it’s rocky Earth or massive Jupiter– are round? It’s ...

NASA scientists have discovered an electric field encompassing Earth’s atmosphere that is as “fundamental” as gravity — and could even give clues about possible life on other planets.

NASA has collaborated with some private players and academic institutions to develop the Quantum Gravity Gradiometer ...

K2-18b, an exoplanet 120 light-years away, may be the best hope to confirm that life exists beyond Earth. Here's what to know ...

Since it is a force, weight is measured in Newtons (not kilograms). The force of gravity is different on different planets, so the weight of an object on different planets (or moons) is different ...

When a planet is born from swirling pockets of molecular gas and dust that surround a young star, it forms under conditions of intense gravity and pressure. The process is violent, the first ...
