A galaxy group in the early Universe
Using the Hubble Space Telescope, an international team of astronomers led by researchers at the Cosmic Dawn Center in Copenhagen, have investigated a galaxy seen almost 11 billion years back in time. Contrary to typical observations, the galaxy was discovered not by the light it emits, but by the light it absorbs. The galaxy itself evades observations, but has at least one nearby companion. Together, these galaxies comprise an early group which may later evolve to resemble the Local Group in which we live.

Hjælp ønskes! Astronomer søger assistance fra frivillige borgere
I et nyt, storslået projekt — Cosmic Dawn Survey — søger professionelle astronomer nu en hjælpende hånd fra offentligheden. Dette observationelle program kortlægger ti millioner af nye galakser, og for at beskrive deres fysiske egenskaber må galakserne organiseres efter diverse kriterier, herunder deres “udseende”. Men i modsætning til de fleste karakteristika i videnskab er en galakses udseende ikke altid objektiv.

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.
