The US space agency (NASA) will launch, on Friday, the largest and most powerful space telescope ever built, to reveal to us new stars and planets, as well as a more detailed view of our solar system that we did not know before, during the next 10 years, and opens a “new eye to the universe.” , according to the Wall Street Journal.
In 1990, the Hubble Space Telescope was launched, which took more than 1.5 million images, and helped reveal that the universe is 13.8 billion years old and expanded our understanding of how planets formed.
“Hubble” dazzled the world in 2004 when it showed an unusual image of deep space showing galaxies as they were up to 13 billion years ago, when the first stars formed or what is known as the “cosmic dawn.”
The new telescope called “James Webb”, which will be launched by NASA on Friday, will be the size of a tennis court and 100 times the power of the Hubble Space Telescope.
It is scheduled to reveal “James Webb” the outer extensions of the universe in more detail than ever before, as it will go beyond what can be seen by “Hubble” and take pictures of some of the first stars and galaxies.
Hubble was primarily designed to capture visible light, which is only a small slice of the spectrum of light emitted by stars and other celestial bodies.
In contrast, a serious telescope will capture a range of infrared light that is invisible to the human eye but makes up much of the light that comes our way from the oldest and most distant galaxies in the universe.
Infrared rays penetrate clouds of gas and dust, allowing Webb to discover new stars and planets.
The human eye can see wavelengths of light ranging from 380 to 700 nanometers, while Hubble can see a range of 90 to 2500 nanometers, and Webb can see a wider range of light wavelengths from 600 to 28,500 nanometers.
Pictures with unusual details
The new telescope features a mirror area approximately 21.5 feet wide, which is three times the size of the “Hubble” mirror, which means that it can take pictures with unusual details, “it can even show the face of Abraham Lincoln on a single shark from a distance of 24 miles,” according to the newspaper. The Wall Street Journal.
The Hubble Space Telescope is still operational, although it suffers from technical problems, and it was planned to operate for only 15 years, that is, until 2005.
The mission of the new telescope is expected to last for five to 10 years, and NASA expects it to produce its first scientific image this summer.
