As Earthlings, most of us don’t spend a lot of extra time thinking about the gravity on our home planet. Instead, we go about our days only occasionally dropping things or tripping over furniture but ...

Astronomers suggest that an alternative concept of gravity, known as modified Newtonian dynamics, could explain orbital inconsistencies that have previously pointed to the existence of a ninth planet ...

Could data pointing toward a mysterious planet at the edge of the solar system actually suggest it's time to revisit our theory of gravity? When you purchase through links on our site, we may earn an ...

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. A team of NASA ...

AUSTIN (KXAN) — A ‘gravity hole’ on Earth? Earlier this summer, researchers with the Indian Institute of Science published a paper exploring one of these ‘gravity holes’. Found all over the planet, ...

Rocky worlds larger than Earth are commonplace in the galaxy, and a few of them may even be habitable. Which poses an interesting question: How difficult would it be for aliens living on these ...

DENVER — Small but rowdy space rocks pushing and jostling one another may have created the unusual orbits some astronomers cite as the signature of the hypothesized "Planet Nine," a new study suggests ...

Recently, an exoplanet just a short 15 light-years from Earth was discovered, setting the scientific community abuzz. This newly found celestial body boasts a unique gravitational pull, a feature that ...

There are several ways that surface gravity on Earth could change. We wouldn’t like most of them. If a mini black hole collided with Earth and didn’t pass straight through, it would sink to the planet ...

How do you explore the interior of a planet without ever touching down on it? Start by watching the way the planet spins, then measure how your spacecraft orbits it -- very, very carefully. This is ...

A 'gravity hole' on Earth? Earlier this summer, researchers with the Indian Institute of Science published a paper exploring one of these 'gravity holes'. Found all over the planet, these are spots on ...
