WebJan 11, 2024 · As stars form, they gather gas and dust, which can look like ribbons in Webb imagery, from the surrounding molecular cloud. The material collects into an accretion disk that feeds the central protostar. Astronomers have detected gas around protostars within NGC 346, but Webb’s near-infrared observations mark the first time they have also ... WebEver deeper and wider look-back surveys have led to a fairly robust outline of the cosmic star-formation history, which culminated around ; this period is often nicknamed “cosmic noon.”Our knowledge about star-forming galaxies at these epochs has dramatically advanced from increasingly complete population censuses and detailed views of …
