Confirmation of the standard cosmological model from red massive galaxies $\sim600$ Myr after the Big Bang

Understand

In their recent study, Labb\'e et al.

• used multi-band infrared images captured by the James Webb Space Telescope (JWST) to discover a population of red massive galaxies that formed approximately 600 million years after the Big Bang.
• The authors reported an extraordinarily large density of these galaxies, with stellar masses exceeding $10^{10}$ solar masses, which, if confirmed, challenges the standard cosmological model as suggested by recent studies.
• However, this conclusion is disputed.
