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 ...

In the cold, dark outskirts of planetary systems far beyond the reach of the known planets, mysterious gas giants and planetary masses silently orbit their stars—sometimes thousands of astronomical ...

A team of astronomers observed a confused exoplanet orbiting its two parent stars in a highly unusual way. As New Scientist reports, the planet, which was first discovered in 2004, is located in a ...

Planets are born, and they can also "die." So what's the lifespan of a typical planet?

Astronomers have found a planet that orbits at an angle of 90 degrees around a rare pair of peculiar stars. This is the first time we have strong evidence for one of these 'polar planets' orbiting a ...

Astronomers have uncovered a distant planetary system that flips a long-standing rule of planet formation on its head. Around the small red dwarf star LHS 1903, scientists expected to find rocky ...

(CNN) — After decades of searching, astronomers have uncovered some of the strongest evidence yet of exoplanets orbiting Barnard’s Star, the nearest single star system to Earth. The four planets are ...

A new Tatooine-like planet outside the solar system may orbit two failed stars, scientists reported Wednesday. Located about 120 light years away, the exoplanet appears to take an unusual path around ...
