This temporal lag is a direct consequence of Albert Einstein’s Theory of General Relativity. The rule is simple: the weaker ...

Learn how Albert Einstein’s theory reveals that time on Mars runs faster than on Earth — and why that tiny shift matters for future space missions.

This update of a classic nursery rhyme was inspired by astronomers in the US, who by serendipity have found a new method of measuring the strength of gravity on the surface of a star. Surface gravity ...

A small star named M82 X-2 breaks physical barriers, as NASA's NuSTAR confirms it shines 10 million times brighter than the ...

For distant stars with planets orbiting them, this gravitational information is key in determining whether any of those planets can harbor life. The new method is described in a study published today ...

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

Ask someone on Earth for the time and they can give you an exact answer, thanks to our planet's intricate timekeeping system, ...

Astronomers have found a clever new way to slice and dice the flickering light from a distant star in a way that reveals its surface gravity, one of the key properties that astronomers use to ...

The surface gravity of a star is a fundamental property, one that depends on the mass and size of the star. But it's also an indication of what's going on in the star's outer layers: higher gravity ...

The way a star flickers can shed light on the strength of gravity's pull on its surface, researchers say. And discovering more about a star's pull can yield key insights on its evolutionary state and ...

"Science rules" has long been Bill Nye the Science Guy's catchphrase, and a silly viral video demonstrating surface gravity on different planets proves Nye correct. In the video, posted on Reddit by u ...
