James Webb: Looking into the past

The American Space Agency, with great pride, published something about the “James Webb Telescope”, which cost ten billion dollars to manufacture, and took 20 years to complete, in cooperation with the European and Canadian Space Agency, and a European rocket carried it to a location two and a half million kilometres away from us, at a point “ Lagrange", after the French-Italian scientist Joseph Lagrange (1736 - 1813), who discovered it more than 200 years ago, as it is one of the points at which the gravitational pull of two large celestial bodies has no effect on a third body that is usually smaller in size, such as a satellite or spacecraft.

The goal of launching the giant telescope was the desire to “look back” by capturing any light from the darkest and smallest points in the sky, in the hope of obtaining new information and images about the universe, and perhaps “catch” the first moments of the life of stars and galaxies. Astronomers are excited about the remarkable images that the telescope will reveal, which will inevitably cause a scientific revolution, and provoke a rapture greater than those caused by the images taken by the Hubble telescope in 1995, which enabled us to look into the distant past, and for the first time thousands of galaxies appeared in Different times beyond 12 billion light-years, specifically in the eXtreme Deep Field image, when the Hubble mirror was pointed at a dark spot in the sky that appears to the naked eye devoid of all light or stars.

The new telescope is designed to capture light waves in the infrared range, which are important in the study of astronomy; Because most of the visible light coming from it is absorbed by the surrounding dust, before it reaches the Earth or to the telescope designed to pick up light waves in the visible rays range.

The sensitivity of the James Webb telescope to infrared rays requires keeping it cool, and preventing any heat from blocking the rays to be captured. This is the function of the Sun Shield, which is the size of a tennis court; It keeps the telescope cool, and blocks the heat of the Earth and the sun.

The James Webb Telescope will start sending images with the summer of this year, and we will know more than we know now about this universe, which is approximately 14 billion years old, and the wonders in it, thanks to the amazing capabilities of this telescope, which does not need maintenance or fuel for the next twenty years. Noting that its manufacture contributed to the advancement of many medical and industrial sciences, especially with regard to lenses, glasses and dozens of other new discoveries, but the mission of the largest and most important telescope lies in its ability to satisfy scientists’ cognitive curiosity, knowing the age and size of the universe, and how far we can look into the deep past.. And much beyond, thousands of billions of light years away!

This happens in the world while we are sitting, or sleeping, on the sidelines of everything that is happening in the world, as if we have nothing to do with what is happening in rapid developments, and there is nothing wrong with that, for these are our true capabilities, and we share this with the majority of the peoples of the earth, but we, with the most regret, Creating the noise around us, and perhaps the most harmful, because of our belief that we are the best, and others have to admit that, and obey it, even if by force!
