In this episode, we will explore one of the most remarkable discoveries made by the James Webb Space Telescope (JWST): a massive and compact quiescent galaxy, which is a type of galaxy that stopped forming stars and is a possible ancestor of giant elliptical galaxies. We will also learn how this galaxy is surrounded by a complete Einstein ring, which is a rare and spectacular phenomenon of gravitational lensing, where the light from a distant galaxy is bent and magnified by the gravity of a closer galaxy. This discovery is not only stunning to look at, but also has profound implications for our understanding of galaxy evolution and cosmology.
