Galaxies at Cosmic Dawn
Since the James Webb Space Telescope began releasing its science observations last month, candidates for increasingly distant galaxies have been reported on a regular basis. In fact, the size and the number of distant galaxies seem to challenge our understanding of how galaxies form, although there are many caveats and alternative explanations. Are we facing a cosmological paradigm shift, are we misinterpreting our data, or are the more mundane reasons? Astronomers at the Cosmic Dawn Center in Copenhagen are working intensely on solving this puzzle.

Galakser ved Cosmic Dawn
Siden Rumteleskopet James Webb begyndte at frigive sine videnskabelige observationer i sidste måned, har vi med jævne mellemrum set rapporter om fjernere og fjernere galakser. Umiddelbart ser det ud til, at galaksernes størrelse og antal udfordrer vores forståelse af, hvordan galakser dannes, selvom der er mange forbehold og alternative forklaringer. Står vi over for et kosmologisk paradigmeskift, fejlfortolker vi vores data, eller kan der være mere banale årsager? Astronomer ved Cosmic Dawn Center i København arbejder intenst på at løse dette mysterium.

James Webb challenges cosmic dawn
Since the James Webb Space Telescope last month began releasing its science observations, candidates for increasingly distant galaxies have been reported on a regular basis. In fact, the size and the number of distant galaxies seem to challenge our understanding of how galaxies form. But before insisting that we are facing a cosmological paradigm shift, there is a long list of reservations and alternative explanations which must be considered. Astronomers at the Cosmic Dawn Center in Copenhagen are working intensely on solving this puzzle.

James Webb udfordrer det kosmiske daggry
Siden Rumteleskopet James Webb sidste måned begyndte at frigive sine videnskabelige observationer, har det tilsyneladende med jævne mellemrum slået rekorden for den fjerneste galakse vi nogensinde har set. Faktisk ser galaksernes størrelse og antal ud til at udfordre vores forståelse af, hvordan galakser dannes. Men inden vi påstår, at vi står overfor et kosmologisk paradigmeskift, er der en lang række forbehold og alternative forklaringer, som vi må tage højde for. Astronomer ved Cosmic Dawn Center i København arbejder intenst på at løse dette mysterium.
