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

Here’s how it works. The Oort cloud is a shell of icy bodies that surrounds the solar system. It begins beyond the Kuiper Belt and even beyond the influence of the sun’s magnetic field ...

“It’s completely plausible for our solar system to have captured such an Oort cloud planet,” says Nathan Kaib, a co-author on the new work and an astronomer at the Planetary Science Institut ...

At the edge of our solar system, a host of large, icy bodies make up the Oort cloud, which appears to sport two spiral arms reminiscent of a disk-shaped galaxy. New research founded upon a simulation ...

The newly found cloud, named Eos after the Greek goddess of dawn, is one of the largest known structures in the sky and one ...

A recent study suggests a relationship between solar cycles and the atmosphere of the solar system’s eighth planet ... And Neptune has ghostly clouds — at least, it used to.

According to researchers, the cloud spans about 40 moon-widths across the sky and has a mass about 3,400 times of the sun. It’s located along the edge of the Local Bubble, a gas-filled cavity in space ...

Previous research has suggested that the Oort cloud contains remnants of the solar system's planets, which were formed over 4 billion years ago, but its exact shape and structure have been a mystery.

the international team of researchers spotted the crescent-shaped gas cloud, dubbed Eos, on the edge of the Local Bubble, an enormous cavity that encompasses our entire solar system. The team ...

A vast star-forming cloud of molecular hydrogen that is one of the largest single structures in the sky has been discovered hidden near the solar system. The crescent-shaped cloud—which its ...

According to the latest paper, the cold cloud compressed the heliosphere in such a way that it briefly placed Earth and the other planets in the solar system outside of the heliosphere's influence.
