The hottest and largest double star system to date, where the two suns – separated by just 7.5 million miles – are in contact and sharing material, has been discovered by astronomers at the European Southern Observatory (ESO). Called “VFTS 352,” this system lies approximately 160,000 light-years from Earth in the Large Magellanic Cloud, and it could be heading for a catatrosphic end, either merging to form a single giant star or a binary black hole. “If the stars are mixed well enough, they both remain compact and the VFTS 352 system may avoid merging. This would lead the objects down a new evolutionary path that is completely different from classic stellar evolution predictions. In the case of VFTS 352, the components would likely end their lives in supernova explosions, forming a close binary system of black holes. Such a remarkable object would be an intense source of gravitational waves,” said Selma de Mink of University of Amsterdam. Click here to view the first image in today’s viral picture gallery.
