These images show the central plane of a rotating disk orbiting a newly formed protostar (dark dot) formed in a three-dimensional model of the shock-triggered collapse of a molecular cloud of gas and dust. Density is shown on the left, while the x velocity plot on the right shows how the shock (outer edge) has injected fingers with motions that are responsible for producing the spin of the disk around the central protostar.

New details about the trigger that may have started the earliest phases of planet formation in our solar system. For decades, it’s been hypothesized that our Solar System’s genesis was initiated by a shock wave from a supernova...
