The earliest stars are believed to have formed during the cosmic dawn era, approximately 100-300 million years after the Big Bang. Detecting these first stars is extremely challenging due to their faintness and the immense distances involved.
The current record holder for the most distant and oldest galaxy observed is GN-z11, discovered by the Hubble Space Telescope in 2016. JWST observations confirmed GN-z11's extreme distance, but it is still too young to host the very first stars.
JWST's infrared capabilities allow it to probe deeper into the early universe, and future observations and data analysis may reveal even more distant galaxies and shed light on the formation of the first stars. However, it is important to note that definitively identifying the first stars may require additional observations, advancements in technology, and further understanding of the early universe.
Nevertheless, JWST continues to push the boundaries of observational astronomy and is transforming our understanding of the cosmos, including the distant past.
