The James Webb Space Telescope is a space telescope jointly developed by NASA, the European Space Agency and the Space Agency of Canada, with the purpose of placing an observatory in space to capture infrared radiation.

According to recent news, the James Webb Space Telescope will have found the most distant galaxy ever observed.

GLASS-z13: The Galaxy discovered by the James Webb Telescope

After the first images from the James Webb Space Telescope, the most powerful ever built, were revealed, scientists may have already identified the most distant galaxy ever observed, which existed 13.5 billion years ago.

Named GLASS-z13, it appears as it did about 300 million years after the Big Bang., 100 million years younger than the previous record, explained to Agence France-Presse (AFP) Rohan Naidu, from the Center for Astrophysics at Harvard. One of the main missions of this new telescope is to observe the first galaxies formed after the Big Bang, which occurred 13.8 billion years ago. The light from this galaxy was emitted 13.5 billion years ago.

James Webb Telescope Finds Most Distant Galaxy Ever Observed

The galaxy was observed by James Webb's NiRcam instrument and detected through what is called the "depth of field", that is, a wider image taken with a long exposure time to detect the faintest lights.

The James Webb telescope, a US$10 billion project, is named after a former NASA administrator and was sent into space on December 25, after successive delays, in a European-made rocket. It is in orbit 1.5 million kilometers from Earth.

Astronomers hope with James Webb to obtain more data on the early days of the Universe, including the birth of the first galaxies and stars, but also on the formation of planets.
