π Webb telescope spots stars using gravity trick
The James Webb Space Telescope utilized gravitational lensing, a spacetime-warping effect, to discover previously unseen stars. This was achieved by observing the Dragon Arc within the Abell 370 galaxy cluster, located about 5 billion lightyears away. The study, involving Dr David Lagattuta, revealed a total of 44 individual stars in this distant region. These stars provide crucial data about the evolution of stars during the Cosmic Noon period. JWSTβs superior resolution and ability to see through dust made this breakthrough possible. π
