James Webb Telescope Captures Quasar’s ‘Einstein Ring’
Summary: The James Webb Space Telescope (JWST) recently captured a stunning image of a quasar, RX J1131-1231, situated about 6 billion light-years away in the constellation Crater. This image features an "Einstein ring," a phenomenon caused by gravitational lensing, where the light from the quasar is bent around an unknown galaxy between the quasar and Earth, creating a halo effect with four bright spots. This discovery not only enhances our understanding of quasars and gravitational lensing but also opens new possibilities for studying distant and faint celestial objects, thereby deepening our knowledge of the universe's structure and history.
