Oort Cloud, Solar System and Spiral

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 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.
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,
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,
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
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.
