James Webb Space Telescope (4 letters crypt.: JWST) is an advanced space observatory that will be the premier observatory of the next decade, serving thousands of astronomers worldwide. It is named after James E. Webb, who was the second administrator of NASA from 1961 to 1968.
The James Webb Space Telescope is set to launch in 2021 and will be the most powerful space telescope ever built. It will be able to see further into the universe than any other telescope before it, allowing scientists to study the first galaxies that formed after the Big Bang, as well as the atmospheres of exoplanets.
The telescope is a joint project of NASA, the European Space Agency (ESA), and the Canadian Space Agency (CSA). It is designed to be a successor to the Hubble Space Telescope, which has been in operation since 1990.
The James Webb Space Telescope will be equipped with a large, segmented primary mirror that is 6.5 meters (21 feet) in diameter, making it much larger than the Hubble’s 2.4-meter (7.9-foot) mirror. This larger mirror will allow the telescope to collect more light and see fainter objects in the universe.
The telescope will also be equipped with four scientific instruments that will allow astronomers to study a wide range of phenomena, from the formation of stars and galaxies to the composition of exoplanet atmospheres. These instruments include a Near Infrared Camera, a Near Infrared Spectrograph, a Mid-Infrared Instrument, and a Fine Guidance Sensor.
Overall, the James Webb Space Telescope promises to revolutionize our understanding of the universe and provide unprecedented insights into the cosmos. With its advanced technology and powerful capabilities, this telescope is sure to make groundbreaking discoveries in the field of astronomy.
