Discovering a machine that could somehow produce thrust without releasing propellant would be a game-changer for human space travel. There’s just one problem—such a device would defy the laws of ...

Buckle up, nerds: NASA is building the first quantum gravity sensor for space—a suitcase-sized instrument that could soon be measuring everything from subterranean water to hidden reserves of ...

You may have heard people say that aboard the International Space Station (ISS) there's "zero gravity," but in fact, gravity is still very much present. The station orbits Earth at an altitude of ...

Gravity and motion make time pass faster on Mars than Earth, reshaping navigation, communication, and future crewed missions.

Here’s what you will learn when you read this story: Gravitational anomalies detected by NASA and the German Aerospace Center’s GRACE satellites confused scientists for years. These anomalies are ...

It's been 286 days since astronauts Sonny Williams and Butch Wilmore have felt the pull of Earth's gravity. Gravity is really, really tough, tough, learning to live with it, but also without it. Our ...

An object's weight on the Moon is approximately one-sixth its weight on Earth, illustrating the variation in gravitational force across celestial bodies. While an object's mass, measured in kilograms, ...

For decades, climate science has focused on what happens on Earth and in our atmosphere, but new research suggests our planet’s long term rhythms are also being nudged by a neighbor. Scientists now ...

Gravity, the force that keeps everything anchored to Earth, is predictable, at least most of the time. But there are places around the world where this fundamental law of nature seems to defy itself.

Here’s what you’ll learn when you read this story: Discovering a machine that could somehow produce thrust without releasing propellant would be a game-changer for human space travel. There’s just one ...
