ALMA focuses on factors influencing star birth in nearby galaxies

30 April 2019 Astronomy Now

The Atacama Large Millimetre/submillimetre Array, or ALMA, is in the process of studying stellar nurseries in nearby galaxies to learn more about the factors influencing rates of star formation and the roles a host galaxy’s overall structure and dynamics might play.
