If you think it’s hard to be in a stable orbit around one star, think of how hard it must be to maintain an orbit around two. Binary star systems are the most common type of star system we have found.

Kepler-47 is a 3.5-billion-year-old star system about 3,340 light years away from Earth. It's one of nine systems that we know of that are "binary star systems," which means it has not one star at its ...

Imagine a world with two different Suns in the sky, similar to Luke Skywalker’s home desert planet Tatooine in “Star Wars.” Such a world exists, as NASA announced in September 2011. But now, NASA has ...

A team of astronomers has found the first transiting circumbinary multi-planet system: two planets orbiting around a pair of stars. This discovery shows that planetary systems can form and survive ...

A new planet has been discovered in a mysterious exoplanetary system about 3,340 light-years from Earth, where two suns rise and set. The 'Kepler-47' system is the only known binary star system to ...

The discovery of the first alien planet with two suns — like the "Star Wars" world Tatooine — residing in its parent star's habitable zone is good news for the search for life beyond Earth, scientists ...

Oh, this is too cool: scientists have found a planet orbiting a binary star (a pair of stars in tight orbit around each other) that is at the right distance to have liquid water! Let me be clear: this ...

Astronomers have for the first time discovered two alien planets whirling around a pair of stars: a complete solar system with twin suns just like Luke Skywalker's fictional home world Tatooine. Most ...

The third planet discovered in the star system Kepler-47 has been identified by scientists as the largest exoplanet within the circumbinary star system. A group of researchers led by astronomers from ...

NASA’s Kepler mission has discovered multiple transiting planets orbiting two suns for the first time. The system, known as a circumbinary planetary system, is 4,900 light-years from Earth in the ...
