"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.

NASA launches NF-5, revolutionizing planetary missions with advanced technology to explore new horizons on the Moon and in ...

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

As a result, the borders of our Solar System remain a bit of a mystery to scientists ... studying the Oort cloud is more about simulation and extrapolation (largely from the paths of comets) than it ...

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.

Explore Earth and its relationships with a plethora of planets, stars and galaxies in its cosmic family, Laniakea, the ...

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 ...
