Solar System, Oort Cloud and Spiral

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.
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.
Mini Galaxy On Fringes Of Solar System, Hidden In Mysterious Icy Cloud Found: Study
A mysterious cloud of space rock and debris in the outer reaches of our solar system might resemble a miniature galaxy, a new study has claimed. The Oort Cloud, named after Dutch astronomer Jan Oort in 1950,
A Hidden Spiral? Scientists Suggest the Oort Cloud May Mimic a Mini Galaxy at the Solar System’s Edge
New research suggests the Oort Cloud may have a spiral structure like a mini galaxy. Supercomputer models reveal its mysterious shape, offering new insights into the edge of our solar system.
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.
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,
Mini 'Spiral Galaxy' May Be Taking Shape At The Edge Of Our Solar System
What they found was surprising: the inner Oort Cloud seems to form a spiral disk, stretching about 15,000 astronomical units (AU) long. 1 AU is the distance between the Sun and the Earth (149.4 million km). The Oort Cloud’s inner edge starts at 2,000 to 5,000 AU, and its outer edge could reach as far as 100,000 AU.
Scientists uncover Oort cloud's spiral structure with the help of NASA supercomputer
A NASA supercomputer has unveiled a cosmic enigma at the solar system's edge, hinting at a miniature galaxy hidden in the icy depths of the Oort cloud.
