The American Space Agency (NASA) on Friday unveiled to us the largest and most powerful space telescope ever built, with new stars and planets, as well as a detailed view of our solar system that we had never known before. Over the next 10 years, and “a new eye for the universe” opens. According to the newspaper,The Wall Street Journal“.
In 1990, the Hubble Space Telescope was launched, which took more than 1.5 million images, helping to reveal that the universe is 13.8 billion years old and expanding our understanding of how planets form.
The world was stunned when “Hubble” showed an extraordinary image of a galaxy in 2004, 13 billion years ago, when the first stars formed, or what was known as the “Cosmic Dawn”.
New telescope calledJames WebbLaunched by NASA on Friday, it will be 100 times the size of a tennis court and 100 times the power of the Hubble Space Telescope.
It is planned to reveal the outer extensions of the “James Web” universe in more detail than before, as it will capture images of some of the first stars and galaxies beyond what can be seen by “Hubble”.
It goes into space to explore the universe like no other telescope before. NASAWEB Contains both cameras and spectrographs, which block light to reveal the chemical composition of cosmic objects.

Discover new stars and planets
Hubble is primarily designed to capture visible light, which is only a small fraction of the spectrum of light emitted by stars and other celestial bodies.
In contrast, an intense telescope captures the band of infrared light invisible to the human eye, but produces most of the light that comes to us from the oldest and most distant galaxies in the universe.
Infrared rays penetrate clouds of gas and dust, allowing the web to detect new stars and planets.
The human eye can see light wavelengths ranging from 380 to 700 nanometers, while Hubble can see wavelengths ranging from 90 to 2500 nanometers, and the Web can see light wavelengths from 600 to 28,500 nanometers wide.
Images with unusual details
The new telescope has a mirror area of about 21.5 feet, which is three times larger than “Hubble” glass, which means it can take pictures with extraordinary details, “it can even show the face of a shark, Abraham Lincoln, from 24 miles away,” says The Wall Street Journal. .
The Hubble Space Telescope is still operational, however, it is plagued by technical problems, and was only scheduled to operate for 15 years, until 2005.
Work on the new telescope is expected to last five to 10 years, and NASA expects to make its first scientific image this summer.
