It’s just a teaser, the full picture is yet to come….NASA reveals unknown facts about the universe from JWST

In a historic move, the National Aeronautics and Space Administration has recently revealed the first image of the mysteries in the universe clicked by the world’s powerful space telescope- James Webb Space Telescope. On July 12,  US President Joe Biden unveiled released the debut photo from NASA’s James Webb Space Telescope – an image of a galaxy cluster revealing the most detailed glimpse of the early universe ever seen.

The details and clarity of the cosmos through the telescope’s eyes have left all enthusiasts amazed. The moment has been called the historic moment as the world now has the deepest infrared image of the universe ever with the help of this powerful telescope. Nasa has released an image of far-flung galaxies as they were 13bn years ago. 

The telescope captured a small slice of the universe, called SMACS 0723 in which shows that particular cluster as it was 4.6bn years ago, as well as the light from many different twinkling galaxies which are among the oldest in the universe. Webb’s NIRCam has brought distant galaxies into sharp focus – they have tiny, faint structures that have never been seen before, including star clusters and diffuse features. Light from these galaxies took billions of years to reach us. We are looking back in time to within a billion years after the big bang when viewing the youngest galaxies in this field. The light was stretched by the expansion of the universe to infrared wavelengths that Webb was designed to observe. Researchers will soon begin to learn more about the galaxies’ masses, ages, histories, and compositions.

Moreover, NASA says it took twelve and a half hours to capture the image. The image consists of many thousands of galaxies. The picture shows several stars in it. The stars with tails in the picture belong to our galaxy, b behind it, thousands of galaxies can be seen. NASA Administrator Bill Nelson said about this that it is the view seen when looking at the universe from a space as small as a grain of sand in the sky.

The $9 billion Webb Observatory, the largest and most powerful space science telescope ever launched, is designed to look through the cosmos at the dawn of the known universe, ushering in a revolutionary era of astronomical discovery. It was launched in 2021 December.  The aim of the mission is to study the origin, evolution and habitability of distant planets. However, the first step of the primary aim to bring out the unknown facts about the universe has now been completed by the telescope, said NASA.
