Planets orbiting two suns are rare. Scientists now understand why. Subtle gravitational forces, amplified by Einstein's relativity, destabilize planetary orbits over eons. This leads to planets being ...

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 ...

The classical picture of star and planet formation suggests that a star’s rotational axis and the orbital planes of its planets should be aligned. However, exoplanetary systems have considerable ...

A planet circling at a sharp 90-degree angle to the orbits of its two host stars has now been confirmed. This discovery challenges long-standing ideas about how planets form and orbit in the cosmos.

Space is full of mysteries that can't be easily explained by the layman, and this latest one from a isn't likely to sour anyone on their fascination with space. Scientists from several institutions, ...

Six planets are set to align on Saturday, creating a planetary parade that will be visible to sky-gazers across the globe.
