Dr.. good cities
A state of astonishment dominated everyone who saw the amazing snapshots of the early universe, when NASA published the first pictures of its new super telescope, which costed ten billion dollars. Amazing discoveries.
It is one of the paradoxes that can not help but stand at it. At a time when nations enter into bloody conflicts, the human mind proves, time and time again, its enormous abilities in invention and discovery, including the discovery of secrets from the universe, in a way that leads us to the question: What if Humans went to this destination alone, and cooperated and collaborated in achieving the noble goals that science leads us to?
We ask that and we know, that an ideal world, like the one we aspire to, will not be achieved unless justice prevails and truth prevails and the good will of mankind triumphs, in building a safe world, free from man’s exploitation of his fellow man, in which famine, injustice and aggression will end.
The efficiency of the telescope, which took amazing pictures, is 100 times more efficient than that of its predecessor, the Hubble telescope, which some sites have called “the godfather of space telescopes.” The telescope bears the name of James Webb, an American astronomer who died in 1992 at the age of 85. He was the second administrator in the history of “NASA”, and had a key role in the “Apollo” programs, because of which Neil Armstrong and Buzz Aldrin walked on the surface of the moon, so the US space agency decided in 2002 that its new telescope would bear his name.
What is also amazing is that the images that the telescope has observed are not images of today. They are views of distant galaxies, nebulae and a planet outside the solar system that are not visible to the naked eye, and the age of some of what we saw in the images dates back to 4.6 billion years ago, which raises the question about: Why are we watching this now? Only, while some of them have been around for billions of years? The answer, scientists say, is that light has a finite speed, so it took up to 13 billion years for the light from some of these galaxies and stars to reach us now.
To make the idea easier for us, and for a simple comparison, the following can be read: “Light takes about one second to travel from the moon and 8 minutes from the sun. So we see the sun as it was 8 minutes ago. And if she disappears, we will find out in 8 minutes.”
