On Tuesday, July 12, or less than two weeks in the future NASA will release the first batch of deep space images from the James Webb Space Telescope (JWST), which has now completed installation and configuration of the devices.
One of these images will show the deepest part of the universe. which is further from Earth than any space telescope has ever seen before. by the former Hubble Space Telescope statistics Can look back as far as space 330 million years after the Big Bang.
Bill Nelson, NASA Administrator, said: He believed in the potential of JWST cameras to break Hubble’s record. By seeing and recording ancient space objects well in the beginning of the universe. More than any other telescope that all humans have ever had.
because the universe is expanding Light traveling further away from the primordial stars of the universe changes frequency, “shifting” more towards the red of the spectrum, turning ultraviolet and human-visible wavelengths into infrared. The JWST camera is capable of detecting the heat of infrared radiation extremely sensitively and accurately.

In addition to the announcement of the historical picture that is prepared to be revealed soon NASA executives also reported that the good news. The process of launching JWST into space and entering orbit over the past several months It can be done quickly and efficiently than expected. This leaves enough fuel as a power source for JWST to extend its mission for another 10 years, which in total means the camera will last up to 20 years.
In a press release on July 12, a team of astronomers from the Space Telescope Science Institute (STScI) in Baltimore, United States. Prepared to reveal the results of the use of the new light spectrum analytical equipment. which is also installed on the JWST camera, they use this state-of-the-art tool Study the chemical composition of the atmospheres of exoplanets, which tells us which molecules in distant stars contain molecules. In particular, is there water or organic matter that is conducive to the existence of living things?
