What Did James Webb Really See at the Beginning of Time?

The James Webb Space Telescope's first full-color images revealed a stunning universe teeming with galaxies, stars, and nebulae in unprecedented detail. Among the most captivating images is that of SMACS 0723, a galaxy cluster that acts as a gravitational lens, magnifying and distorting the light from distant galaxies behind it. This image, known as Webb's First Deep Field, allowed astronomers to peer back in time approximately 13.5 billion years, offering a glimpse into the early universe and the formation of the first stars and galaxies. The observations provided valuable insights into the evolution of the universe, the properties of dark matter and dark energy, and the nature of black holes, pushing the boundaries of our knowledge about the cosmos.
