Oort, Edge and Spiral Arms

The Mysterious Oort Cloud at the Edge of the Solar System Might Have Spiral Arms Like a Tiny Galaxy
In the farthest reaches of our solar system, beyond the familiar planets and even the icy Kuiper Belt, lies a mysterious region known as the Oort cloud. This is a vast shell of icy bodies, stretching thousands of times farther from the Sun than Earth.
Oort cloud resembles a galaxy, new study finds
A shell of icy objects at the edge of the solar system known as the Oort cloud has a pair of spiral arms that resemble a miniature galaxy, new research suggests.
NASA supercomputer finds Milky Way-like spiral at solar system’s edge
The inner Oort cloud, between 1,000 and 10,000 AU from the sun, displays a spiral formation with arms that extend 15,000 AU.
NASA’s supercomputer reveals unexpected spiral at the outer limits of the solar system
Groundbreaking research reveals the Oort Cloud's shape as a spiral structure, challenging traditional beliefs about its random collection. NASA's Plei
NASA supercomputer reveals strange spiral structure at the edge of our solar system
The mysterious Oort cloud is the source of many of our solar system's comets, but astronomers still have no idea what it looks like. Now, new simulations may have given them a first glimpse.
The Oort Cloud Forms a Spiral at the Outskirts of Our Solar System
Learn about the Oort cloud, a vast area beyond the inner solar system that is believed to contain icy objects arranged in a spiral shape.
A spiral structure in the inner Oort cloud
We typically think of the Oort cloud as scattered ice balls floating far from the sun, yet still tied to it gravitationally. Occasionally, some wayward gravitational perturbation will knock one of them a weird way and create a long-period comet,
NASA supercomputer suggests the Oort Cloud may be a spiral, like a miniature galaxy
The Oort Cloud begins roughly 2,000 – 5,000 astronomical units (AU) from the Sun, with 1 AU being the average distance between Earth and the Sun.
NASA Supercomputer Uncovers a Mysterious Spiral Lurking at the Edge of the Solar System
A hidden structure at the farthest reaches of our solar system is challenging long-held theories. Using advanced simulations, a NASA supercomputer has revealed that the Oort Cloud, a vast shell of icy bodies surrounding the Sun,
Mysterious cloud at solar system’s edge found to host strange ‘mini galaxy’
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
New study claims our solar system is home to millions of interstellar objects
Researchers claim that there could be at least 1 million interstellar objects hiding in the Oort Cloud at the edge of our ...

Surprise Spiral Shape Revealed in The Darkness Surrounding The Solar System
Most of the long-period comets in the Solar System come from the outer Oort Cloud. The inner region is much more stable. It's closer to the Sun, which means it's more strongly bound by the Sun's ...
Scientists Think Visitors From Another Star System May Have Infiltrated Our Galactic Neighborhood
Sure, they’re particles and rocks, but they’re still a fascinatingly long way from home. Alpha Centauri is the star system ...
