What you see in the center of the screen now is the 'next-generation space telescope' launched by the United States last year, and a picture of distant space taken by James Webb.



It looks like a collection of sparkling jewels, but reporter Seo Dong-gyun will explain the meaning of this photo.

Last Christmas, NASA launched a telescope called James Webb into space.



A giant telescope measuring 6.5 meters in diameter sent us a picture of space.



The image released by NASA was taken of the galaxy 'SMACS 0723', which is 4.6 billion light-years from Earth.



In other words, it is what the galaxy looked like 4.6 billion years ago.



The image on the right is of the same galaxy taken by the largest telescope ever, the Hubble Telescope, but a quick glance reveals that James Webb took it in more detail.



You can see the part where the light bends, which looks like a shooting star.



This is a phenomenon called 'gravity lensing' caused by strong gravity.



Until now, I couldn't figure out where this light was coming from.



Zooming in on a picture taken by James Webb reveals what appears to be a cluster of invisible stars.



Due to the gravitational lensing effect, light can be seen 2-3 times further away than the SMACS 0723 galaxy, which is estimated to be a star cluster when the galaxy was formed 12 to 3 billion years ago.



Also, scientists speculate that the faint white dots at the edge of the image may be light from an early galaxy 13.5 billion years ago.



[Seongcheol Yang / Senior Researcher, Korea Astronomy Research Institute: The meaning of this first published image is that we observed galaxies in the early universe.

This is a very important discovery in the sense that the clusters were still born together when the earliest galaxies were formed...

NASA is releasing another additional photo taken by James Webb tonight (12th).



Over the next 20 years, James Webb will explore the secrets of the universe as well as the existence of life in the universe one by one.
