'Puzzling' object discovered by James Webb telescope may be the earliest known galaxy in the universe

SMRTR summary

The James Webb Space Telescope discovered a mysterious bright object called Capotauro that astronomers believe could be either the universe's earliest known galaxy or an unusually cold brown dwarf. If it's a galaxy, Capotauro formed just 100 million years after the Big Bang, pushing back the age of the oldest known galaxy by 200 million years.
