The outcomes were provided on Monday at the 243rd Meeting of the American Astronomical Society.Using information from the National Radio Astronomy Observatorys (NRAO) Atacama Large Millimeter/submillimeter Array (ALMA) the group caught images of Class 0 and Class I planetary disks, which are much more youthful than the Class II disks observed by earlier disk surveys. “ALMAs early observations of young protoplanetary disks have actually exposed numerous beautiful rings and gaps, possible formation sites of planets,” said Cheng-Han Hsieh, PhD Candidate at Yale University, “I wondered when these rings and gaps began to appear in the disks.
