The Hubble Space Telescope has generated the most comprehensive survey yet of the Andromeda galaxy, the nearest galactic neighbor to the Milky Way. The new mosaic of about 2.5 billion pixels yields new clues to the galaxy’s history. UW astronomers presented the findings Jan. 16 at a meeting of the American Astronomical Society.
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.
An image captured earlier this year by the Hubble Space Telescope may look like a ghostly apparition, but it is not. Hubble is looking at a titanic head-on collision between two galaxies.
As part of a University of Washington-led project, NASA’s Hubble Space Telescope has produced a stunningly detailed portrait of the Triangulum Galaxy, displaying a full spiral face aglow with the light of nearly 25 million individually resolved stars.
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.
