Gravitational Lens Catches Light of First Stars at z≈10

In the field of galaxy cluster Abell S1063, the JWST telescope uncovered a gravitational arc GAR10 at redshift about 10. Its unusually blue ultraviolet continuum and excess flux in the F200W filter point to extreme conditions. Spectral fitting with two models yields two possible explanations: either

Prodigy Galaxy: A Barred Spiral at the Dawn of Time

The James Webb Space Telescope spotted galaxy M1149-BSG-z5 at redshift 5.1 — with clear spiral arms, a massive bar, and an active nucleus. With a stellar mass of 10^10.45 M☉, it churns out 144 stars per year and has already accumulated half the Sun's metallicity. In the company of a neighbor and in
