Detailed explanation-1: -Explained: NASA’s Webb Telescope and the first look at the universe from 13 billion years ago.

Detailed explanation-2: -Part of the image is light from not too long after the Big Bang, which was 13.8 billion years ago. Seconds before he unveiled it, President Joe Biden marveled at the image he said showed “the oldest documented light in the history of the universe from over 13 billion – let me say that again – 13 billion years ago.

Detailed explanation-3: -Hubble, the observatory, is the first major optical telescope to be placed in space, the ultimate mountaintop. Above the distortion of the atmosphere, far far above rain clouds and light pollution, Hubble has an unobstructed view of the universe.

Detailed explanation-4: -The Royal Astronomical Society (RAS) previously criticized NASA for not immediately addressing concerns that Webb persecuted queer employees; the NASA-led James Webb Space Telescope (JWST or Webb) that launched in December 2021 is named after him.

Detailed explanation-5: -The most distant of the galaxies detected by Webb displayed a redshift of 13.2, which corresponds to an age of about 13.5 billion years - the highest ever measured for any galaxy. “At redshift 13, the universe is only about 325 million years old,” Robertson said.
