Astronomers Discover One of the Most Massive Binary Stars in the Galaxy
Using archival Hubble Space Telescope data and new observations, astronomers have precisely measured the binary star system NGC3603-A1 in the starburst region NGC 3603, located 22,000 light years from the Sun. This system consists of two massive stars weighing approximately 93 and 70 times the mass of the Sun, orbiting each other every 3.8 days, making it one of the most massive and fastest-orbiting binary systems discovered in our galaxy.
