James Webb Space Telescope Launches

The James Webb Space Telescope launched aboard an Ariane 5 rocket from Kourou, French Guiana. After a month-long journey to the Sun-Earth L2 point and a complex deployment sequence, JWST began science operations in July 2022. Its 6.5-metre gold-coated primary mirror observes in infrared, revealing the earliest galaxies formed after the Big Bang and analysing exoplanet atmospheres.
