When massive stars die, they explode, leaving behind supernova remnants. Given how common binary star systems are - more than ...

A new theory published today in the Astrophysical Journal Letters by scientists from Harvard University suggests that the sun may once have had a binary companion of similar mass. If confirmed, the ...

How many Earth-sized exoplanets orbit binary star systems (two-star systems)? This is what a recent study accepted by Astronomy & Astrophysics hopes to address as an international team of researchers ...

This graphic shows the relative size of the Sun, upper left, compared to the two stars in the binary system known as Wolf-Rayet 140, or WR 140. The O-type star is roughly 30 times the mass of the Sun, ...

Washington DC — New theoretical work shows that gas-giant planet formation can occur around binary stars in much the same way that it occurs around single stars like the Sun. The work is presented ...

Stars are the fundamental building blocks of our universe. Most stars host planets, like our Sun hosts our solar system, and if you look more broadly, groups of stars make up huge structures such as ...
