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 ...

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 ...

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, ...

Could a lonely planet wander aimlessly through the restless galaxy change the subtle dance of gravity within our solar system? Astronomers have new cause to investigate. With powerful telescopic ...

A theory developed to replace dark matter may mean bad news for Planet Nine, a hypothetical as-yet-unseen world in the outer solar system. The odd orbital alignments of icy objects in this region that ...

As the story goes, mathematician Sir Isaac Newton was sitting in an orchard after supper when he saw an apple fall from a tree. He wondered why apples always fall straight to the ground, instead of ...

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 ...

In 2007, something strange happened over the eastern Atlantic Ocean. According to satellites orbiting Earth, our planet's gravity field developed a continent-scale anomaly before subsiding to its ...

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 ...

The GRAVITY instrument on ESO’s Very Large Telescope Interferometer (VLTI) has made the first direct observation of an exoplanet using optical interferometry. This method revealed a complex ...

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 ...
