JWST aims to address several key questions in astrophysics and cosmology:
Formation of Stars and Planets: JWST will probe the formation and evolution of stars and planetary systems, including the study of protoplanetary disks and exoplanets. First Light and Reionization: One of its primary goals is to observe the first galaxies that formed after the Big Bang and to understand the era of reionization. Galaxy Formation and Evolution: The telescope will study the assembly and growth of galaxies over cosmic time. Origins of Life: JWST will investigate the conditions for life in the universe by analyzing the atmospheres of potentially habitable exoplanets.
