Ultra-Deep Radio Map of the Milky Way Unmasks Hidden Remnants
Astronomers released the most detailed low-frequency radio image of the Milky Way’s southern Galactic Plane, built from 141 nights of observations with the Murchison Widefield Array in Western Australia and processed with over a million CPU hours for the GLEAM-X survey. The map doubles previous resolution and sensitivity, catalogs about 98,000 radio sources, and reveals numerous supernova remnants and star-forming regions, along with insights into pulsars. It marks a milestone in low-frequency radio astronomy and lays groundwork for future SKA-Low observations.
