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 ...

The Solar System continues to surprise us day after day and its presence in terms of dominance and expansion goes far beyond what we thought. And indeed, a long way from Neptune an ...

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 ...

An international team has discovered a giant spiral disk galaxy in the early cosmos which is three times larger than similar ...

A recent image from the Hubble Space Telescope captures a gorgeous spiral galaxy bursting with new star formation.

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 ...

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 ...

Groundbreaking research reveals the Oort Cloud's shape as a spiral structure, challenging traditional beliefs about its random collection. NASA's Pleiades supercomputer simulations suggest the ...

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 disk, when viewed from a distance, would appear as a spiral structure with two twisted arms," the authors wrote. Those "arms" resemble the elongated structures of a spiral galaxy, like our ...
