How James Webb Space Telescope Works

The James Webb Space Telescope is a space-based observatory that uses cutting-edge technology to study the universe in unprecedented detail. At its core, the telescope features a 6.5-meter primary mirror made of 18 hexagonal segments, which work together to collect and focus light from distant objects. This mirror is coated with a thin layer of gold, which reflects infrared radiation with high efficiency. The telescope's instrumentation includes a range of cameras and spectrographs that are designed to detect and analyze the light collected by the primary mirror. These instruments are cooled to extremely low temperatures, which allows them to detect the faint signals from distant stars and galaxies. The telescope's technology also includes a sophisticated cryogenic cooling system, which uses a combination of radiators and refrigerators to cool the instruments to temperatures as low as 7 Kelvin. Some of the key technologies used by the James Webb Space Telescope include:

Infrared detectors that can detect the faint signals from distant stars and galaxies

The James Webb Space Telescope is able to spot distant stars like Earendel due to its advanced optics and instrumentation. Earendel is a star that is located over 13 billion light-years away, and it is one of the most distant stars that has been observed so far. The telescope's ability to detect Earendel is a testament to its sensitivity and resolution, and it has provided scientists with a unique opportunity to study the properties of this distant star. The telescope's instruments are able to detect the light from Earendel by using a technique called gravitational lensing, which allows them to amplify the faint signal from the star. The telescope's advanced optics and cryogenic cooling system also enable it to detect the star's infrared radiation, which is shifted towards longer wavelengths due to the expansion of the universe. By analyzing this radiation, scientists can learn more about the properties of Earendel, including its temperature, size, and composition.
