Astronomers have already cataloged nearly 4,000 exoplanets in orbit around distant stars. Though we have learned much about these newfound worlds, there is still much we do not know about the steps of planet formation and the precise cosmic recipes that spawn the wide array of planetary bodies we have already uncovered, including so-called hot Jupiters, massive rocky worlds, icy dwarf planets, and – hopefully someday soon – distant analogs of Earth.The Epoch of Planet Formation, Times Twenty
To help answer these and other intriguing questions about the birth of planets, a team of astronomers using the Atacama Large Millimeter / submillimeter Array (ALMA) has conducted one of the deepest surveys ever of protoplanetary disks, the planet-forming dust belts around young stars. ...
Known as the Disk Substructures at High Angular Resolution Project (DSHARP), this Large Program of 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. ...
