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.

The Sun makes Earth habitable, governs its climate and drives a variety of natural phenomena through its variable magnetism. Indeed, all planets in and outside the Solar System exist under the ...

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 young star called V1298 Tau is giving astronomers a front-row seat to the birth of the galaxy’s most common planets. Four ...

V1298 Tau links swollen young worlds to the compact planets that astronomers keep finding, and its timing signals made that ...
