Rice University astronomer Andrea Isella and his co-principal investigators have issued the first results from a major study of protoplanetary disks observed around stars at the Atacama Large Millimeter/submillimeter Array, the world’s most powerful radio telescope in the high plains of Chile. The new data gathered over hours of observation of the 20 target stars revealed they share common features like bright and dark rings, but no two are alike. (Credit: Sean Andrews/DSHARP/ALMA)
