New analysis strengthens the "born together" hypothesis, which posits that stars are born with companions. Models even back up the idea that the solar system’s sun has a twin.

Latest study has led researchers to believe that all stars are born with twins. In the sun's case, Nemesis, as it is called, may have been responsible for the end of the dinosaurs.

For the first time, researchers have found evidence that rocky planets may exist in a double sun system located some 1,000 light-years away from Earth. SDSS 1557 resembles Tatooine, Luke Skywalker’s home planet in 'Starwars' that orbited twin suns.

Two stars in a binary system are so close, they're sharing material as they spin about each other, scientists say. The end result is likely to be a cosmic cataclysm, they say.
Space October 21, 2015
Rare binary star system features a white dwarf actively consuming its much larger companion star, astronomers say. The result could be a supernova explosion, they say.

Astronomers have discovered a young binary system with two potential exoplanets beginning to form.
Space July 31, 2014
Researchers at Ohio State University, along with amateur astronomers from around the globe, discovered an Earth-like exoplanet in a binary star system. Astronomers previously believed Earth-like, or rocky, planets could not exist in binary systems.
Space July 6, 2014
Scientists discover a rocky, icy planet with an Earth-like orbit circling one star in a system of two stars. Experts believe this expands the ground where the search for extraterrestrial life continues.

The discovery of LAMOST-HVS1, the closest and the second brightest among the 20 “hypervelocity” stars found, could unlock the mystery behind the black hole and the dark matter.
Space May 11, 2014
Researchers have discovered an 'upside-down planet' with unusual gravitational lensing characteristics. The self-lensing planet may lead to the development of new techniques that could be used to study binary star systems.
