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 ...

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 ...
