Using the James Webb Space Telescope (JWST), astronomers have performed near-infrared observations of a dwarf galaxy known as Ark 227. The observational campaign led to the serendipitous discovery of an extended stellar halo ...
Stars escape from their birth place and eventually become dispersed across the galaxy. This is an important process in galactic evolution. Theoretical studies suggest two possible reasons why stars escape. First, stars may ...
