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 ...

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 ...

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 ...

Why is Christian Science in our name? Our name is about honesty. The Monitor is owned by The First Church of Christ, Scientist, and we’ve always been transparent about that. The church publishes the ...

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 ...

The planet Mars shares numerous characteristics with our own. Both planets have roughly the same amount of land surface area, sustained polar caps, and both have a similar tilt in their rotational ...
