Learn why only 14 out of over 6,000 exoplanets orbit two stars, and how Einstein’s general theory of relativity may be to blame.

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth.

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, ...

V1298 Tau links swollen young worlds to the compact planets that astronomers keep finding, and its timing signals made that connection measurable. Future transit-timing and atmospheric observations ...

Because their orbits are unstable, a possibility exists that the asteroids could break off from their current trajectory and one day head on a collision course for Earth. The Venusian space rocks are ...
