What modern observation directly validates the existence of the protoplanetary structures predicted by the hypothesis?
Answer
Direct observation of protoplanetary disks orbiting young stars.
The nebular hypothesis has moved beyond being merely a historical explanation for our solar system; it is now a currently active model validated by contemporary astronomy. Powerful modern telescopes allow astronomers to directly view other star systems in the process of formation. In star-forming regions, such as the Orion Nebula, astronomers witness protoplanetary disks exhibiting clear evidence of dust concentrations, gaps, and structures, which strongly confirm the predicted mechanism of planet formation occurring within a flattened, gaseous medium.
