Help wanted! Astronomers seek assistance from citizen scientists
In a new, magnificent project — the Cosmic Dawn Survey — professional astronomers are seeking the assistance from the public. The survey is unveiling tens of millions of new galaxies, and to describe their physical properties these galaxies need to be organized according to various criteria, including their “appearance”. But unlike most features in science, the appearance of a galaxy is not always objective.

James Webb’s “too massive” galaxies may be even more massive
The first results from the James Webb Space Telescope have hinted at galaxies so early and so massive that they are in tension with our understanding of the formation of structure in the Universe. Various explanations have been proposed that may alleviate this tension. But now a new study from the Cosmic Dawn Center suggests an effect which has never before been studied at such early epochs, indicating that the galaxies may be even more massive.

Nearby galaxies help astronomers understand distant galaxies
To better understand observations of the most distant galaxies, an international team of astronomers has built a sample of local galaxies which can be studied in much higher detail. In a newly published study they show how the amount of light that escapes from a galaxy is connected to its physical properties. The result has implications for how we interpret observations of galaxies in the early Universe.
