Fjernest kendte galakse-kandidat opdaget af James Webb
Mindre end en uge efter at rumteleskopet James Webb blev klar til sine videnskabelige optagelser, kom de første rapporter i preprint om rekordfjerne, og dermed rekordtidlige, galakser. Endnu mere bemærkelsesværdigt er det, at galakserne ser ud til at være så tunge, at de udfordrer vores forståelse af, hvordan struktur dannes i Universet. Nu har de første to af disse rapporter gået gennem den obligatoriske fagfællebedømmelse, og gør dermed resultaterne mere robuste. Men astronomerne venter stadig på det afgørende bevis — spektroskopi.

Farthest galaxy candidate yet known discovered by James Webb
Less than a week after the James Webb Space Telescope was ready for science, the first reports of discoveries of galaxies at record distances and, consequently, at record-early times appeared in preprints. Even more remarkably, these galaxies seem to be so massive that they challenge our understanding of how structure forms in the Universe. Now the two first of these reports have undergone the mandatory peer-review and have been accepted for publication in the scientific journal The Astrophysical Journal Letters, substantiating the robustness of the result. However, astronomers are still waiting for the conclusive evidence — spectroscopy.
