The James Webb Space Telescope (JWST), set to launch on December 25, 2021, is poised to revolutionize our understanding of the universe. This groundbreaking telescope is the largest and most powerful space telescope ever made, with a hefty price tag of over $10 billion and almost two decades of meticulous construction.
One of the most impressive features of the JWST is its primary mirror, which spans 6.5 meters (21.3 feet) across, dwarfing the Hubble Space Telescope’s 2.4-meter (7.9-foot) mirror. This larger mirror gives the JWST six times the light capturing capacity, enabling it to see deeper into space than ever before.
While the Hubble was designed to capture visible and ultraviolet light, the JWST is optimized for capturing infrared light. This allows the JWST to peer through cosmic dust clouds and observe celestial objects much further back in time than previously possible. It can resolve images of galaxies more crisply, providing a clearer view of the universe’s early days.
In fact, the JWST has already observed galaxies dating back to just 320 million years after the Big Bang, shedding light on the formation of the first galaxies. These groundbreaking observations may challenge the current cosmological model and prompt a reevaluation of our understanding of the universe.
With its unparalleled capabilities, the JWST promises to uncover new mysteries of the cosmos and push the boundaries of our knowledge. As it begins its mission, scientists and astronomers anticipate that the JWST will unveil unprecedented insights into the universe’s origins and evolution, potentially leading to a complete rewrite of our cosmological understanding. Stay tuned as the JWST embarks on a journey to unveil the secrets of the universe.
