The most powerful space telescope ever created will search the dark ages of the universe


Scientists’ explanation James Webb Space Telescope NASA says it is the most powerful space telescope ever built, and after many years of delays and billions of dollars in spending, the telescope is set to launch into orbit and soon begin the next era of astronomy.

According to the American “Space” website, the evidence shows that The universe It began 13.8 billion years ago in an event called the Big Bang, which was very hot and dense. Immediately after the Big Bang, the universe began to expand and cool.

Also, a second after the Big Bang, that is Vision of the universe It is one hundred trillion miles away, with an average temperature of 18 billion degrees Fahrenheit (10 billion degrees Celsius).

About 400,000 years after the Big Bang, the universe was 10 million light-years wide, with temperatures cooling to 5,500 degrees Fahrenheit (3,000 degrees Celsius), and if anyone could see it this time, the universe would glow. Dull red like a heat lamp. This is the beginning of what astronomers call the “dark age” of the universe.

The Dark Ages ended when the first stars and galaxies formed by gravity, which eventually began to emit the first light, and although astronomers do not know when the first light occurred, the best guess is that it happened hundreds of millions of years after the Big Bang. , And astronomers do not know whether stars or galaxies formed first.

Current theories, based on how gravity forms the structure of a dark-dominated universe, suggest that small objects, such as stars, first formed and then evolved into dwarf galaxies and later into large galaxies such as the Milky Way.

Astronomers like to study this important age of the universe, but finding the first light is the biggest challenge, compared to today’s larger and brighter galaxies, the James Web Deep Space makes this possible.
