Early in our Solar System’s history, bits of icy debris were scattered and then gradually coaxed into a spiral alignment in ...

In a groundbreaking discovery, NASA's Pleiades supercomputer has revealed an unexpected spiral structure within the inner ...

Estimating the cloud's structure requires more than understanding ... According to their model, the Oort cloud looks like a spiral disk about 15,000 au across, offset by the ecliptic by about ...

"We were quite surprised," Dones continued. "Spirals are seen in Saturn's rings, disks around young stars and galaxies. The ...

The Solar System continues to surprise us day after day and its presence in terms of dominance and expansion goes far beyond ...

Even the little-understood Oort Cloud, at the outer edges of our solar system beyond view, has a partly spiral structure.

The Oort cloud is a shell of icy objects that forms the very outskirts of our Solar System. Recently, a group of researchers discovered that the inner portion of the Oort cloud likely has spiral arms ...

Now, researchers have developed a new model that suggests the inner structure of the Oort cloud may look like a spiral disk. They published their findings Feb. 16 on the preprint server arXiv ...

The Oort cloud is traditionally thought of as ... "The disk, when viewed from a distance, would appear as a spiral structure with two twisted arms," the authors wrote. Those "arms" resemble ...

Pairing an analytic model with the supercomputer simulation, they concluded that the numerous bodies within the inner Oort cloud form a spiral structure that stretches about 15,000 au in length and is ...
