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

The relative quantities of volatile gases like methane and ethane can reveal key details about distant Kuiper Belt objects.

The triple star system is sending comets, asteroids and meteors our way, and the number of interstellar objects entering the solar system will rise.

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

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

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 ...

Floating around at the edge of the Solar System are leftovers from its formation. This is the Kuiper Belt, which is composed ...

The latter behaved more like a typical comet but still appeared to have traveled from well beyond our solar system. However, new simulations suggest that these weren’t isolated objects.

The identity of this presumed cloud is not fully known, but scientists strongly believe that it is a source of long-period comets (LPCs) that enter the inner solar system from time to time and can ...

Astro Brief is a collaboration between KSMU, the Missouri Space Grant, and MSU's Department of Physics, Astronomy and ...

A spiral structure composed of billions of comets in the inner solar system at its heart. | Credit: Robert Lea (created with Canva) Spirals are a repeating theme in astronomy, with arguably the ...
