An accidental discovery in an astronomy show offers researchers a new clue about the mysterious Oort Cloud, a large expanse ...

Astronomers using the James Webb Space Telescope have captured breathtakingly detailed images of two giant exoplanets ...

This video is a part of a series looking at the Outer Solar System. The Oort Cloud is believed to be a vast cosmic shell at the edge of our Solar System that astronomers have never directly seen.

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 ...

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 ...

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.

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.

If you’re in the path of totality or nowhere near Monday’s solar eclipse ... these clouds to form and persist as they’re a key component in the climate system,” he said.

The ice giant’s ghostly, cirrus-like clouds largely disappeared four years ... more intense ultraviolet radiation bombards the solar system. With data from NASA’s Hubble Space Telescope ...
