![]() Unlike Hubble, which observes in the near ultraviolet and visible (0.1 to 0.8 μm), and near infrared (0.8–2.5 μm) spectra, Webb observes a lower frequency range, from long-wavelength visible light (red) through mid-infrared (0.6–28.3 μm). ![]() This gives Webb a light-collecting area of about 25 square meters, about six times that of Hubble. Webb's primary mirror consists of 18 hexagonal mirror segments made of gold-plated beryllium, which combined create a 6.5-meter-diameter (21 ft) mirror, compared with Hubble's 2.4 m (7 ft 10 in). The first Webb image was released to the public via a press conference on 11 July 2022. The James Webb Space Telescope was launched on 25 December 2021 on an Ariane 5 rocket from Kourou, French Guiana, and arrived at the Sun–Earth L 2 Lagrange point in January 2022. Webb, who was the administrator of NASA from 1961 to 1968 during the Mercury, Gemini, and Apollo programs. The primary contractor for the project was Northrop Grumman. The NASA Goddard Space Flight Center (GSFC) in Maryland managed telescope development, while the Space Telescope Science Institute in Baltimore on the Homewood Campus of Johns Hopkins University currently operates Webb. National Aeronautics and Space Administration (NASA) led Webb's design and development and partnered with two main agencies: the European Space Agency (ESA) and the Canadian Space Agency (CSA). Scientists submit findings to the STScI news office for consideration and potential dissemination, enabling NASA to deliver reliable information about Webb's remarkable achievements."Chronological List of James Webb Discoveries" are available on the internet and interested readers can refer to it to stay updated with the latest scientific breakthroughs. As the telescope continues observations, a growing pipeline of peer-reviewed articles will fuel future Webb news. Webb's groundbreaking discoveries undergo scrutiny by experts in accredited journals, bolstering their scientific credibility. The peer review process ensures the quality of scientific results before publication. James Webb Space Telescope has successfully completed its commissioning activities and captures stunning images and spectra of the universe, with data stored at the Mikulski Archive for Space Telescopes. ![]() ![]() This enables investigations across many fields of astronomy and cosmology, such as observation of the first stars, the formation of the first galaxies, and detailed atmospheric characterization of potentially habitable exoplanets. As the largest optical telescope in space, it is equipped with high-resolution and high-sensitivity instruments, allowing it to view objects too old, distant, or faint for the Hubble Space Telescope. The James Webb Space Telescope ( JWST) is a space telescope currently conducting infrared astronomy. ![]()
