The Oort cloud, a theoretical spherical shell surrounding our solar system, extends from approximately 1,000-2,000 AU to potentially 100,000 AU, halfway to Alpha Centauri. Its existence is inferred ...

We typically think of the Oort cloud as scattered ice balls floating far from the sun, yet still tied to it gravitationally.

NASA's James Webb Space Telescope turned to the famed ringed world of Saturn for its first near-infrared observations of the planet in 2023. The Oort clous is thought to have been formed by remnants ...

In the farthest reaches of our solar system, beyond the familiar planets and even the icy Kuiper Belt, lies a mysterious ...

An accidental discovery might change how we think about one of the most mysterious structures in our solar system. The Oort Cloud, a large expanse of icy bodies revolving around the sun at a distance ...

Astronomers searching for the faintest glimmers of light beyond distant Pluto say they’ve discovered a new dwarf planet – and that this planetoid’s movements hint that an invisible giant planet ...

The Oort Cloud's inner edge begins approximately 2,000-5,000 AU from the Sun, extending to a nebulous outer boundary of 10,000-100,000 AU (0.16-1.6 light-years). The proximity of the Oort Cloud to the ...

Here, we show that the detection of Borisov implies that interstellar objects outnumber Solar system objects in the Oort cloud, whereas the reverse is true near the Sun due to the stronger ...

Rocky fireballs like the one that fell over Alberta, Canada last year shouldn't originate from the icy Oort Cloud... but this one apparently did. When you purchase through links on our site, we may ...
