SUMMARY: Astronomers with the Harvard-Smithsonian Center for Astrophysics have found the heaviest star ever seen - 80 times the mass of our Sun - and it's got a twin. Located 20,000 light-years from Earth, the two massive stars in WR 20a go around each other every 3.7 days. These two stars are very young, probably only 2-3 million years old, and highly unstable. It'll only be a few more million years before they explode, one after the other as supernovas.
