Needle in a haystack: JWST searches for the very first galaxies ever formed

A study led by Pablo Pérez-González at the Centro de Astrobiología in Spain with collaborating scientists from the Department of Astronomy at Stockholm University recently discovered nine galaxies that are candidates of being the most distant galaxies known. By using a combination of images taken with the NIRCam instrument on the James Webb Space Telescope (JWST) and the so called drop-out technique these galaxies could be picked out from more nearby objects. The light coming from these galaxies was sent out a mere 100-200 million years after Big Bang, which means that they could be some of the very first galaxies formed in the universe.

First light with 4MOST

On October 18 2025, the 4-metre Multi-Object Spectroscopic Telescope (4MOST) facility, installed on the VISTA telescope at the European Southern Observatory’s (ESO) Paranal Observatory in Chile, obtained its first light. This milestone is a crucial step in the lifecycle of a telescope and marks the moment in time when it is ready to begin its scientific journey.
