Webb Telescope: Unveiling the Universe's First Stars

The James Webb Space Telescope (JWST) may be able to find the Universe's first stars, known as Population III stars, with the help of gravitational lensing. These ancient stars formed shortly after the Big Bang and played a crucial role in the reionization of the Universe. By detecting these massive stars, the JWST could provide observational evidence for the Epoch of Reionization and shed light on the early stages of the Universe. However, identifying these stars spectroscopically is challenging due to factors such as binary pairs and surrounding nebulous hydrogen. If successful, the JWST will further solidify its status as a groundbreaking telescope.
