Astronomers have recently uncovered a remarkable planetary system around the faint orange star WASP-132, featuring two exoplanets that couldn’t be more different. One is a rocky world that completes ...

General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...

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.
