JAMES WEB TELESCOPE

The James Webb Space Telescope (JWST) is a large, infrared-optimized space telescope set to launch in December 2021. It is a joint project of NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA).

The JWST is the successor to the Hubble Space Telescope and will have a much larger mirror and better sensitivity in the infrared part of the spectrum, allowing it to observe the most distant objects in the universe, including the first galaxies that formed after the Big Bang. It is also designed to study the atmospheres of exoplanets, and to investigate the formation and evolution of stars and galaxies.

Features:

The JWST has a 6.5-meter primary mirror, which is made up of 18 hexagonal segments that can fold up to fit inside the rocket for launch. Once in space, the mirror will unfold and begin its mission. The telescope will be positioned at the second Lagrange point (L2), a location about 1.5 million km (930,000 miles) from Earth, where it will have a clear view of the universe without interference from Earth's atmosphere or the Sun's heat.

The JWST is expected to operate for at least 10 years, and it will be a valuable tool for astronomers to study the early universe and the origins of life.
