Explanation

The James Webb Space Telescope (JWST) is the largest and most powerful space observatory ever launched into space. It features a primary mirror measuring 6.5 meters across, providing unprecedented infrared sensitivity to observe the early universe. Statement 2 is also correct as the JWST is a major international collaboration led by NASA in partnership with the European Space Agency (ESA) and the Canadian Space Agency (CSA) [1]. ESA provided the Ariane 5 launch vehicle and key scientific instruments like NIRSpec, while CSA contributed the Fine Guidance Sensor and NIRISS. The mission launched on December 25, 2021, and is currently positioned at the second Lagrange point (L2), approximately 1.5 million kilometers from Earth, to conduct transformative research in cosmology and astronomy.
