Dark skies
There is no escaping light pollution on Earth — not on the seafloor or at the poles. Even above us, low-Earth orbit is crowded with artificial satellites and space debris that reflect light and spoil Hubble Space Telescope images (pictured).

Asteroid Surfaces
Recent missions to the asteroids Ryugu and Bennu have revealed that the surfaces of asteroids can be actively shaped by a variety of geological processes.

The impact of astronomy on climate change
The global climate crisis has prompted the astronomy community in recent years to assess, primarily, the impact of its activities upon climate change, and secondarily, the impact of climate change upon astronomy.

Dwarf galaxies
Dwarf galaxies — galaxies of mass less than roughly a billion solar masses — have emerged as key laboratories for testing a number of open questions in astrophysics, including the formation of the first stars and the chemical enrichment of the Universe, the growth of galaxies and of the black holes within them, and the existence and properties of dark matter.

Nobel Prize in Physics 2020
We present this Collection of research, review and comment from Nature Research to celebrate the award of the 2020 Nobel Prize in Physics to Roger Penrose “for the discovery that black hole formation is a robust prediction of the general theory of relativity” and to Reinhard Genzel and Andrea Ghez “for the discovery of a supermassive compact object at the centre of our Galaxy”.

Dawn XM2 at Occator crater
Close to the end of its mission, the Dawn spacecraft performed high resolution observations of Occator crater at Ceres in order to study its bright points (faculae) at unprecedented detail. These observations establish Ceres as an ocean world.

Planetary Interiors
Recent years have been an exciting time to unravel the mysteries of planetary interiors. A number of ongoing international space missions, ever evolving new technologies and numerical methods, and re-analysis of existing data are allowing us to gain new insights on the internal structures of planetary bodies.
