ALMA
Millimeter/submillimeter array studying cold gas, dust and planet formation.
Overview
ALMA is a 66-antenna millimeter/submillimeter array on the Chajnantor plateau in Chile, observing cold dust and gas invisible to optical telescopes. It has transformed views of planet-forming disks and dusty galaxies in the early universe.
Key discoveries
- Ring and gap structures in protoplanetary disks
- Detection of complex organic molecules in disks
- Characterization of dusty submillimeter galaxies at high redshift
