At an epic timescale "comparable to the age of the solar system," which is 4.6 billion years old, the researchers believe that the spiral arms formed when "small bodies" were pushed out of the ...

The edge of the Solar System is a strange place, full of oddities we've only just begun to probe. But perhaps the oddest of all is the Oort Cloud, a vast field of icy debris extending out to ...

NASA supercomputer finds Milky Way-like spiral at solar system’s edge. Mrigakshi Dixit. Mon, February 24, 2025 at 12:58 PM UTC. 3 min read.

At the edge of our solar system, a host of large, icy bodies make up the Oort cloud, which appears to sport two spiral arms reminiscent of a disk-shaped galaxy. New research founded upon a simulation ...

Groundbreaking research published on February 16, 2025, turns centuries-old assumptions about the shape of the outer edge of the solar system upside down. The Oort Cloud, traditionally thought to ...

An accidental discovery in an astronomy show offers researchers a new clue about the mysterious Oort Cloud, a large expanse of icy bodies revolving around the sun.

The mysterious cloud of space rocks and debris at the edge of the solar system may have spiral arms, making it resemble a mini galaxy, a new study says.

The combination of these factors could explain why Earth is the only planet known to exhibit plate tectonics today. In a 2022 study, Collins and his colleagues found that Jupiter's icy moon Europa ...

The inner part of the system, between 1,000 and 10,000 AU from the sun, displays a spiral formation with arms that extend ...

The spiral theory helps to illuminate the dynamics of our solar system, according to Faherty. “If you’re going to come up with a theory of how solar systems evolve, you should take into ...

The Oort cloud is traditionally thought of as a vast shell of perhaps trillions of icy objects encasing our solar system, the final boundary between us and the reaches of interstellar space. But it's ...
