A team of astronomers has conducted ALMA’s first large-scale, high-resolution survey of protoplanetary disks, the belts of dust and gas around young stars. Known as the Disk Substructures at High Angular Resolution Project (DSHARP), this “Large Program” of the Atacama Large Millimeter/submillimeter Array (ALMA) has yielded stunning, high-resolution images of 20 nearby protoplanetary disks and given astronomers new insights into the variety of features they contain and the speed with which planets can emerge. The results of this survey will appear in a special focus issue of the Astrophysical Journal Letters.
