How a new planetarium show helped scientists unlock a cosmic secret

NEW YORK (AP) — Scientists have unlocked one of the solar system’s many secrets from an unexpected source: a planetarium show opening to the public on Monday.

At the American Museum of Natural History last fall, experts were hard at work preparing “Encounters in the Milky Way,” a deep dive into our home galaxy shaped by the movements of stars and other celestial objects.

They were fine-tuning a scene featuring what’s known as the Oort Cloud, a region far beyond Pluto filled with icy relics from the solar system’s formation.
