NASA’s $10 billion telescope, the James Webb Space Telescope, is designed to capture the first glimpse of the universe shortly after the Big Bang. The target is at the European Space Agency’s French Guiana Kourou on Saturday, December 25 at 7:20 am Launched from the European Space Agency’s Kuru launch site on Christmas Day. In the next ten years, this revolutionary world’s first space science observatory will capture the earliest galaxies believed to have formed during the formation of the early universe. The new telescope will help scientists probe the structure and origin of our universe and our position in it. But after launching, Weber will deploy a sun visor the size of a tennis court, which will block MIRI and other instruments from the heat of the sun and allow them to passively cool down. Starting approximately 77 days after launch, MIRI’s cryogenic cooler will take 19 days to reduce the temperature of the instrument’s detector below 7 Kelvin. Penanen explained that for the space observatory, a physically compact, energy-efficient cooler instrument is needed. It must be highly reliable because we cannot go out and repair it. “So these are the challenges we face. In this regard, I would like to say that the MIRI cryogenic cooler is definitely at the forefront.” The 7.2-ton James Webb Space Telescope [JWST] will be launched from Northeast South America on the Ariane 5 rocket. The coast launch is designed to capture starlight from the first galaxies and will be the largest telescope ever put into orbit by NASA. One of Weber’s scientific goals will be to study the properties of the first generation of stars that formed in the universe. Weber’s near-infrared camera or NIRCam instrument will be able to detect these extremely distant objects, and MIRI will help scientists confirm that NASA explained that these faint light sources are clusters of first-generation stars, rather than forming as galaxies evolve Of the second generation of stars.
