Planets Form Where?? ALMA Observations Show Planet Formation in Harsh Environments

New research using the Atacama Large Millimeter/submillimeter Array (ALMA) telescope reveals that planet formation can occur in harsh, high-radiation stellar environments. This contradicts earlier assumptions and suggests planet formation is more resilient than previously thought. The study observed protoplanetary disks within the Sigma Orionis cluster, finding structures indicating potential planet formation despite intense ultraviolet radiation from a nearby star. These findings expand our understanding of planetary formation and its prevalence throughout the galaxy, informing studies of our own solar system's origins. The high-resolution images obtained by ALMA were crucial to these discoveries. Join communications specialist Beth Johnson for an interview with lead author Dr. Jane Huang about this new research, its impact on understanding our solar system, and how it relates to the search for habitable worlds.
