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 ...

This video explains how the solar system formed and why most planets move in the same direction, using basic physics and ...

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 ...

This is a brilliant question because the notion of an orbit is counterintuitive. We know that massive objects (really, any objects with mass) gravitationally attract other massive objects; Newton's ...

In a discovery that's fit for a movie, Northwestern University astronomers have directly imaged a Tatooine-like exoplanet, orbiting two suns. While obtaining an image of a planet beyond our solar ...

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 ...
