The first full-color image from the James Webb telescope revealed the oldest structures in the universe
After years of planning and efforts, finally moments before the first full-color image of the James Webb Space telescope was unveiled and with the revelation of the oldest recorded moments of the universe so far, Another long historical step was taken for humanity. Now, with the help of the James Webb Space Telescope, humanity has taken its deepest look into the universe, and another important and valuable event in the path of space exploration. Contemporary man was born. The importance of James Webb's first full-color scientific image is so great that Joe Biden, as the president of the United States of America and the highest official of this country, personally unveiled it. The previous announcement was made after half a year of launching the most powerful observatory into space. After the launch, the telescope, while unfolding in an origami-like process, reached the Sun-Earth Lagrangian point 2 within a month, and then it was the turn of the scientific instruments to move slightly to be ready for observation.

The James Webb Space telescope has four state-of-the-art instruments designed to study everything from solar system objects to distant, ancient galaxies that formed just a few hundred million years after the early universe's Big Bang. . These instruments are now fully prepared for scientific observations.

And now, with the help of scientific instruments, the first full-color image of James Webb has been recorded and published. This image shows the deep field of SMACS 0723 galaxy clusters.
These are huge galaxy clusters that, based on Einstein's general relativity, magnify and distort the light of the objects behind them by forming a gravitational lens, and it is possible to observe They provide a deep field of very distant and intrinsically faint galactic populations. The light that reached us about 13.5 billion years ago.

The James Webb Space Telescope's first
If you hold a grain of sand outstretched toward the sky, the small area it occupies is about the size of the telescope's field of view. The web is in this picture and now you can imagine how many galaxies, including early galaxies, can be seen in just this small area, and how small it is still compared to the whole sky.
According to NASA, this The image is not our farthest view of the universe. Non-infrared missions such as COBE and WMAP have observed the universe at moments closer to the Big Bang, about 380,000 years after. When only the microwave background radiation was present, but no stars or galaxies. The Webb telescope is set to observe a few hundred million years after the Big Bang in search of the oldest coherent structures in the universe.
Other early science images from James Webb will be released as previously scheduled on Tuesday, July 12 at 10:30 a.m. local time. Eastern time (July 21 at 19:00 Tehran time) will be published, which will include photos of the Carina Nebula and the Southern Ring, the gaseous exoplanet WASP-96b.
The powerful James Webb telescope The threshold of a new era of space exploration and will especially help scientists to study the formation of early galaxies, the conditions of the evolution of the solar system and the origin of life on exoplanets in unprecedented detail.
