Our solar system is probably on the mild side compared with what happens elsewhere. You probably need that mildness in order to have a habitable planet.” The Nice model is a hypothesis ...

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

DALLASI absolutely love this, it's called an orrery, and it's a little mechanical model of our solar system. You can see the planets here, orbiting the sun as they would do in real life.

The James Webb Space Telescope has captured its first direct images of carbon dioxide in a planet outside the solar system in ...

Interstellar material has been discovered in our solar system, but researchers continue to hunt for where it came from and ...

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

The solar system drifts inside an immense, low-density cavity known as the Local Hot Bubble (LHB). This region, spanning at least 1,000 light-years, radiates X-rays due to its searing million-degree ...

This journey through a dense region of space could have compressed the heliosphere, the protective bubble surrounding our solar system, and increased the influx of interstellar dust, potentially ...

In research highlighted in a new paper, published today in The Astrophysical Journal, Scientia Senior Lecturer Ben Montet and PhD candidate Brendan McKee analysed changes in the timing of a known ...

Researchers used a supercomputer to model the structure of the Oort cloud based on the trajectories of comets as well as the gravitational forces within and beyond our solar system. They ...
