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.

The final parsec problem is an astronomical puzzle involving the dynamical evolution of supermassive black holes (SMBHs) at the centres of most galaxies.

In cosmology, the prevailing model that describes the universe is the Lambda Cold Dark Matter (ΛCDM) model.

In late 2018, the European Space Agency's Mars Express orbiter gathered exciting radar data suggesting the presence of liquid water beneath Mars' south polar ice cap.

Since its launch in late 2021, the James Webb Space Telescope (JWST) has revolutionized our view of the universe, giving us unprecedented details of distant galaxies and stars.

So-called ‘Super Earths’ are described as planets with masses that exceed that of the Earth’s, but remain lighter than the ice giants in our system.
