If you need to remember your tiny place in the space-time continuum, it’s time to listen to SolarBeat, a flash animation that converts the orbital frequencies of our solar system into notes. Artist ...

Nearby red dwarfs are turning into rich laboratories for studying small rocky worlds. One such star now stands out as a system with four or more planets, including at least one in the habitable zone ...

A newly analyzed planetary system has turned up a world orbiting at such a skewed angle that it defies the neat textbook picture of how planets are supposed to form and settle around their stars. The ...

Theorbits of Jupiter, Saturn, Uranus and Neptune may have been altered by the fly-by of an enormous object from deep space, billions of years ago. According to a pre-print research paper, which is yet ...

WASHINGTON, Feb 14 (Reuters) - Astronomers have observed a planetary system that challenges current planet formation theories, with a rocky planet that formed beyond the orbits of its gaseous ...

The Sun is an incandescent but benevolent dictator. For billions of years, it’s kept our star system well organized through the influence of its powerful gravity. All the planets revolve around it on ...

Studying the orbits of thousands of exoplanets shows that large planets tend to have elliptical orbits, while smaller planets tend to have more circular orbits. This split coincides with several other ...

In theory, it could happen – one of the very first solutions to the three-body problem was this scenario. But it is very unlikely to be stable over time. You need the stars to have near equal mass and ...
