| Solving a 30-year-old problem in massive star formation Posted: 27 Jan 2014 11:17 AM PST Astrophysicists have found evidence strongly supporting a solution to a long-standing puzzle about the birth of some of the most massive stars in the universe. Young massive stars shine brightly in the ultraviolet, heating the gas around them, and it has long been a mystery why the hot gas doesn't explode outwards.
