It took several decades of design and construction, followed by 6 months of calibration of its instruments in space and alignment of its mirrors that led to this historic moment for the James Webb telescope. This high-precision tool has now shown its ability and revealed the first image it ever captured to the world.

This is just the first of a batch of spectacular images that will soon be shown to the world. With this first revelation, the James Webb telescope has brought the deepest-ever view of the universe.

It was yesterday at the end of the day that Joe Biden, the President of the United States, released the first photograph captured by the James Webb telescope.

In this image it is possible to see several galaxies and the lights that reflect a small portion of the universe, something that experts compared to the size of a simple grain of sand.

The sharpest, "deeperest" image of the universe

According to NASA, the "Webb's First Deep Field" represents the sharpest and "deetest" image of the distant universe that we have to date. It represents a snapshot of a cluster of galaxies known as SMACS 0723 as they appeared 4.6 billion years ago.

The combined mass of all the galaxies depicted in the image acts as a gravitational lens, magnifying the much more distant celestial bodies seen in the background. Some of the galaxies have never-before-seen features that astronomers will soon be studying to learn more about the history of our universe.

NASA makes it clear that this first image does not represent the first view of the universe. Microwave telescopes like the Cosmic Background Explorer (COBE) captured closer snapshots of the Big Bang, but they didn't offer a view of stars and galaxies like the one presented by NASA now.

James Webb Telescope Has More Surprises

James Webb has been in development for over two decades, with an investment of $10 billion, and was launched in 2021, on Christmas Day. The project is the result of a collaboration between NASA, the European Space Agency and CSA, the Canadian space agency.

The image that Joe Biden shared today is just the first of an expanded batch of photos that NASA is predicting this week. The rest of the initial list will arrive during today, when NASA holds a press conference. These are expected to be as interesting or more interesting than the one presented now.
