In the early days of space travel, two large space telescopes werde installed in Earth's orbit - the Hubble Space Telescope (HST) and the James Webb Space Telescope (JWST). Both telescopes have changed the look of humanity to the universe crucial and made many new discoveries possible.
The James Webb Space Telescope (JWST), previously known as Next Generation Space Telescope (NGST), was the flagship-class space observatory of NASA. The JWST was the successor instrument to the Hubble Space Telescope and the Spitzer Space Telescope. The JWST has been launched in 2018 and is named after James E. Webb, the second administrator of NASA, who played an integral role in the Apollo program.
While Hubble had a 2.4-meter (7.9 ft) mirror, the JWST featured a larger and segmented 6.5-meter (21 ft) diameter primary mirror has been located near the Earth-Sun L2 point. A large sunshield keep its mirror and four science instruments below 50 Kelvin.
JWST's capabilities enabled a broad range of investigations across the fields of astronomy and cosmology. One particular goal involved observing some of the most distant objects in the Universe, beyond the reach of ground and space-based instruments.
This included the very first stars, the epoch of reionization, and the formation of the first galaxies. Another goal was understanding the formation of stars and planets. This include imaging molecular clouds and star-forming clusters, studying the debris disks around stars, direct imaging of exoplanets, and spectroscopic examination of planetary transits.
History of the Future
In 2025, the JWST found the first Earthlike planet with an ESI of 0,9021 which was mankind's most important discovery until then. Unfortunately, the JWST has been disabled in 2029 because of strong cost savings at NASA when the new NASA amusement park suffered unexpected high losses and a great new planet had been discovered already. It stayed at the L2 point because it was too expensive to destroy it and it was considered safe to not fall on anyone's head.
