The two heaviest stars ever have been discovered in the southern Milky Way galaxy. The double super heavyweights are actually in orbit around each other, and both break the record 83 times the suns mass for the most massive stars found to date. The heavier of the two weighs in at a whopping 114 "solar masses," while its little brother is 84 solar masses. The discovery was presented June 7 at the meeting of the Canadian Astronomical Society at the Royal Military College of Canada in Kingston, Ontario. The two big bruiser stars, which form a binary system called A1, are not only large, they are quite young. This makes sense since it is the largest and brightest of stars that live the briefest, according to stellar theory.
