Webb will unfurl a sun cover the size of a tennis court after launch to protect the MIRI and other equipment from the Sun’s heat. However, because the telescope’s electronic devices will emit infrared light, its instruments must be extremely cold, around 40 kelvins (388° Fahrenheit below zero or 233° Celsius below zero), while the detectors inside the mid-infrared instrument (MIRI) must be even colder, less than 7 kelvins (448° Fahrenheit below zero or 266° Celsius below zero). There won’t be many to find at that time, but the Webb telescope can see them if they’re there, and if we’re lucky, we’ll discover them,” he told. “We believe that stars, galaxies, and black holes may have formed 100 million years after the Big Bang. “They’ll be simply small red dots,” says Nobel prize winner and JWST senior project scientist John Mather.

To detect light, the telescope, which has a 21-foot-wide (6.5-meter) mirror and four super-sensitive detectors, will look at a very tiny region in the sky for days. The Webb telescope will cost around $10 billion (€9 billion) to develop, deploy, and operate in space for five years. Its second aim is to find planets outside our solar system and study their atmospheres for evidence of life. Its primary aim is to investigate the early stages of the universe by collecting infrared light from the cosmos in order to shed insight into the universe’s origins. The principal missions of the telescope are as follows. James Webb Space Telescope finally gets a launch dateĪfter 14 years of delays, NASA’s James Webb Space Telescope, the biggest space observatory in history, will launch on an Ariane 5 rocket from the Guiana Space Center in Kourou, French Guiana on December 24. One of Webb’s objectives will be to investigate the attributes of the universe’s initial generation of stars.The Webb telescope will cost around $10 billion (€9 billion) to develop, deploy, and operate in space for five years.
