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

Galaxies in the far universe with a mysterious orange dot .

Alternatively, Capotauro may be an extraordinary brown dwarf (a "failed star" that is more massive than the largest gas giant planets but not large enough to sustain nuclear fusion in its core) that lives on the outer edges of the Milky Way while smoldering at a mere 80 degrees Fahrenheit (27 degrees Celsius).
