In a real-life twist on Star Wars' Tatooine—a harsh desert planet with twin suns and a criminal underbelly—astronomers have found a bizarre new world that orbits two stars at a perfect right angle.

Astronomers have discovered a planet beyond the solar system that orbits its twin parent stars closer than any ever seen before in a binary. The twin stars in the sky over the newly-found extrasolar ...

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.

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.

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 ...

While our Sun prefers to go solo, many other stars are parts of binary systems, with a pair of stars gravitationally bound to each other. In some cases, the stars are far enough apart that planets can ...

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 ...
