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.

Some of the most promising places to look for extraterrestrials have remained, so far, mostly hidden from astronomers. Now a game-changing instrument called NIRPS (Near-Infrared Planet Searcher) is ...

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.

Astronomers have long faced a strange contradiction: most stars are born in pairs, and ...

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.

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 ...

Astronomers are increasingly finding planets that do not simply circle their stars in neat, clockwork ellipses but instead trace out paths that look more like intricate choreography. The latest ...

The origin of super-Earths and sub-Neptunes has been revealed in a system of four young planets that are dramatically losing ...
