JWST Illuminates the Universe’s First Billion Year
A new Perspective published in Nature Astronomy provides the most comprehensive snapshot yet of the Universe’s first Billion years, as revealed by the James Webb Space Telescope (JWST). Drawn from the collective insights of an international assemblage of leading astronomers, the work charts a transformative moment in cosmic research—an era where science textbooks are being rewritten in real time.
Schematic illustration of the history and evolution of the universe—from the Big Bang 13.8 Billion years ago to present day—based on our current knowledge and the ground-breaking new insights provided by the James Webb Space Telescope (JWST). Graphically represented are the Big Bang, the Cosmic Inflation, the Dark Ages, the first galaxies, stars and black holes, the Hydrogen reionisation, and the JWST amongst present-day style galaxies within an ever expanding playground called universe. This graphic by Fabio Crameri (ISSI Bern) is available via the open-access s-ink.org repository.

At the Department of Astronomy, we use observations from optical to radio wavelengths combined with modelling to understand how galaxies were formed and evolve.
