With the gap between them very gradually narrowing as the binary system loses energy, the fact that they are so massive and ...

The image of Luke Skywalker gazing wistfully across the desert of Tatooine while a pair of “suns” set on the horizon is among ...

No planet in our solar system has a polar orbit. The several exoplanets known to follow such a path orbit only a single star. When two stars, or in this case two brown dwarfs, orbit each other, it is ...

An international team led by researchers in Japan and Europe has discovered a new multi-planet system around a sun-like star ... an experiment to test whether gravity behaves as a quantum entity ...

Scientists recently announced the first detection of gravitational waves created by two neutron stars smashing ... to eight times the size of our own sun before exploding in catastrophic supernovae.

Venus and Jupiter, bracketing the sun ... be affected by gravity. The French mathematician Pierre-Simon Laplace even proposed, in 1795, that gravity could be strong enough to pull light into ...

The difference this time is that two stupendously precise detectors ... yet in familiar contexts like the gravitational pull of the Sun or Earth, Einstein’s predictions barely differ from ...

Just as the Earth pulls water downwards (in waterfalls, for example), the weaker gravitational pull of the Sun and Moon pull water sideways across the Earth. Why do we have two tides a day?
