Scientists have unlocked one of the solar system's many secrets from an unexpected source: a planetarium show.

The inner section of the Oort Cloud, made of billions of comets, resembled a bar with two waving arms, similar to the shape of our Milky Way galaxy.. Scientists had long thought the Oort Cloud was ...

For context, the Oort cloud is a spherical shell of comets and icy bodies that exist out beyond the orbit of Neptune, which ...

The Oort cloud’s inner edge lies 2,000 to 5,000 Astronomical Units (AU) ... both from within our solar system and from ...

Scientists had long thought the Oort Cloud was shaped like a sphere or flattened shell, warped by the push and pull of other planets and the Milky Way itself. The planetarium show hinted that a ...

The Oort Cloud, an expanse of icy bodies in the far reaches of our solar system, is shown here in a scene from "Encounters in the Milky Way," a show at New York City's Hayden Planetarium that ...

When the objects in the Oort cloud interact with passing stars, dust clouds or even the weak gravitational tidal forces created by the Milky Way galaxy, they may spiral inward toward the sun ...

The inner Oort cloud, between 1,000 and 10,000 AU from the sun, ... both from within our solar system and from external sources like other stars and the Milky Way galaxy's center.

For context, the Oort cloud is a spherical shell of comets and icy bodies that exist out beyond the orbit of Neptune, which is located around 2.8 billion miles (4.5 billion kilometers) from the sun.
