Scientists will study nearby galaxies to uncover galactic formation history and dark matter
NASA’s upcoming Nancy Grace Roman Space Telescope will look for “fossils” of galaxy formation by conducting high-resolution imaging studies. Through a grant from NASA, astronomers are designing a set of possible observations called RINGS — the Roman Infrared Nearby Galaxies Survey — that would collect these images, and the team is producing publicly available tools that the astronomy community can use once Roman launches and starts collecting data.

Caught in the act: UW astronomers find a rare supernova ‘impostor’ in a nearby galaxy
UW astronomers Breanna Binder and Ben Williams have identified a rare type of ‘supernova impostor’ in a nearby galaxy, with implications for how scientists look at the short, complex lives of massive stars.
