Roman's Galactic Bulge Time Domain Survey Graphics

  • Released Wednesday, November 8, 2023

Roman’s main objective in the Galactic Bulge Time Domain Survey is finding new planets and black holes. Astronomers anticipate that Roman could discover over 1,000 microlensing and 100,000 transiting planets from this survey alone. Observatories like the James Webb Space Telescope can then follow up with a narrower, more targeted view and learn key details about the most interesting discoveries.
