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 ...
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 ...
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 ...
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 ...
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 ...
The life of a star is determined by its mass. Large stars live short lives that end in supernova explosions, while smaller stars live longer, ending their lives as white dwarfs. Knowing the mass of a ...
Just as waves ripple across a pond when a tossed stone disturbs the water's surface, gravity waves ripple toward space from disturbances in the lower atmosphere. Just as waves ripple across a pond ...
(This is an expanded version of an earlier post, taking into account escape velocity as well as surface gravity.) Earth-sized exoplanets have been very much in the news lately. In early November ...
"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 ...
The picture above is not actually a map of the topography * (height variation) of the Indian Ocean seafloor, as much as it looks like it. It’s actually a map of the change in the Earth’s gravity field ...
Astronomers have found a clever new way to slice and dice the flickering light from a distant star in a way that reveals the strength of gravity at its surface. That is important because a star's ...
