The James Webb Space Telescope is a large, infrared-optimized space telescope. As the largest, most powerful telescope ever launched into space, Webb will fundamentally alter our understanding of the universe.
Webb was launched on December 25, 2021, and arrived at its final destination, Lagrange Point 2, a month later. After a lengthy process of unfolding and cooling down, Webb began its first science observations in July 2022.
Webb's mission is to study the first lights from the Big Bang, to search for exoplanets, and to study the formation of galaxies. Webb's unprecedented capabilities will allow astronomers to answer questions that have been around for centuries.
Here is a timeline of the James Webb Space Telescope:
1996: NASA begins studying the feasibility of a successor to the Hubble Space Telescope.2002: NASA selects the James Webb Space Telescope as the successor to Hubble.2005: Construction on Webb begins.2011: All 18 primary mirror segments are completed.2014: Webb is shipped to Kourou, French Guiana, for launch.2018: Webb is delayed due to technical problems.2021: Webb is launched on December 25.2022: Webb arrives at L2 on January 24.2022: Webb begins first light observations on July 12.
Webb's mission is expected to last for at least five years, but it could last much longer. Webb is a revolutionary telescope that will change the way we see the universe.
