The James Webb Space Telescope (JWST) is a space telescope currently conducting infrared astronomy. It was launched on 25th December 2021 on an Ariane 5 rocket from Kourou, French Guiana, and arrived at the Sun–Earth L2 Lagrange point in January 2022. The first JWST image was released to the public via a press conference on 11 July 2022. The telescope is named after James E. Webb, who was the administrator of NASA from 1961 to 1968 during the Mercury, Gemini, and Apollo programs.
JWST is the largest telescope that is rendering into the space to conduct analysis of astronomical objects using infrared (IR) radiation. The telescope is equipped with high-resolution and high-sensitivity instruments. JWST can view and capture the objects that are too old, situated at far distant or faint to be captured by the Hubble Space Telescope. The mass of the JWST is half about as that of Hubble Space Telescope. These features of JWST enables it to perform investigations across many fields of astronomy and cosmology.
NASA conducted the design and development of the JSWT with two main space agencies, European and Canadian Space agency, ESA and CSA. The development was carried out at the NASA Goddard Space Flight Center in Maryland. The Space Telescope Science Institute currently operated the JWST.
JWST operates in a halo orbit, circling around a point in space known as the Sun–Earth L2 Lagrange point, approximately 1,500,000 km (930,000 mi) beyond Earth's orbit around the Sun. Its actual position varies in between 250,000 and 832,000 km (155,000–517,000 mi) from L2 as it orbits, keeping it out of both Earth and Moon's shadow.
Hubble Space Telescope
The Hubble Space Telescope was launched in 1990 into the lower Earth Orbit. It is one of the largest Telescope to conduct the study of astronomy. The Hubble telescope is named after astronomer Edwin Hubble.
