SHOCKING Discovery In The Milkyway!

SHOCKING Discovery In The Milkyway!

The James Webb Space Telescope (JWST) is a space telescope designed primarily to conduct infrared astronomy. The U.S. National Aeronautics and Space Administration (NASA) led development of the telescope[8] in collaboration with the European Space Agency (ESA) and the Canadian Space Agency (CSA).[9] The JWST was launched 25 December 2021 on an ESA Ariane 5 rocket from Kourou, French Guiana[10] and is intended to succeed the Hubble Space Telescope as NASA's flagship mission in astrophysics. The telescope is named after James E. Webb, who was the administrator of NASA from 1961 to 1968 during the Mercury, Gemini, and much of the Apollo programs.

With greatly improved infrared resolution and sensitivity, it will view objects too old and distant for Hubble—some up to 100 times fainter. This is expected to enable a broad range of investigations across the fields of astronomy and cosmology, such as observations of first stars and the formation of the first galaxies, as well as detailed atmospheric characterization of potentially habitable exoplanets.

The Optical Telescope Element, consists of 18 hexagonal mirror segments made of gold-plated beryllium which combine to create a 6.5-meter (21 ft) diameter mirror, compared to Hubble's 2.4 m (7.9 ft). This gives the Webb telescope a light collecting area about 6.25 times as large as Hubble's: Webb's collecting area is 25.37 square meters compared to Hubble's 4.0. Unlike Hubble, which observes in the near ultraviolet, visible, and near infrared (0.1–1.0 μm) spectra, JWST will observe in a lower frequency range, from long-wavelength visible light (Red) through mid-infrared (0.6–28.3 μm). The telescope must be kept extremely cold, below 50 K (−223 °C; −370 °F) to observe faint signals in the infrared without interference from any other sources of warmth. It is deployed in a solar orbit near the Sun–Earth L2 Lagrange point, about 1.5 million kilometers (930,000 mi) from Earth, where its five layer kite-shaped sunshield protects it from warming by the Sun, Earth and Moon.
