The solar system lies embedded within a sparse region of the interstellar medium 1000 lyr across, known as the local bubble.

Relative to solar-system timescales, Saturn’s rings are believed to be quite young, estimated to be only 100–400 million years old. This estimate is based on the remarkable purity of the material composing the rings.

When observing our closest neighbouring stars, astronomers quickly realised that our Sun stands out from its peers of similar age, possessing a notably greater metallicity.

Beyond the outskirts of the Solar System lies the cold classical belt (CCB), a stable region within the Kuiper Belt.

Hubble has made new observations of Jupiters Great Red Spot, revealing that the anticyclone is not as stable as it might appear.

On the 27th of August, the Asteroid Terrestrial-impact Last Alert System (ATLAS), observing from Sutherland, South Africa, captured data on asteroid 2024-PT5.

It has been proposed by MIT physicists that if most of the dark matter in the universe is incorporated into microscopic primordial black holes, these should race through our solar system at least once per decade at veloci

A significant challenge in modelling the early solar system is explaining the presence of liquid water on Earth.

At its most basic the Sun, and other stars, act as large dipoles.

This month, all the planets of our Solar System are visible !

New ideas about the way the solar system formed arrive just in time as NASA announces the extension of 8 of its planetary missions !

Our understanding of our closest companions in space is far from complete: there are 8 planets, over 200 moons and many more small objects like dwarf planets, asteroids and comets to look at.
