Last Wednesday (2), NASA released Important Images from the James Webb Telescope. The new records feature detailed pictures of the galaxy cluster known as "El Gordo".
The estimated location of galaxies is about 10 billion light years from planet Earth. The set of galaxies presents new perspectives on the formation of the universe.

Thus, the telescope is helping scientists to better understand how cosmic structures developed over time.
Likewise, the Webb telescope expedition validated a theory made by albert einstein100 years ago, when verifying the phenomenon of gravitational lensing in the galaxy “El Gordo”.
“Gravitational lensing was predicted by Albert Einstein more than 100 years ago. In the El Gordo cluster, we see the power of gravitational lensing in action,” said Rogier Windhorst, from the University of Arizona, United States.
The further away a galaxy is, the longer its light takes to reach Earth. So by capturing the light from these remote galaxies, Webb gives us a direct view of the universe.
From the potential of the telescope and Einstein's gravitational theory, the researchers noticed that "El Gordo" acts as a cosmic magnifying glass, thus its gravity distorts light.
In this way, “El Gordo's lens increases the brightness and enlarges the sizes of distant galaxies. Such a lensing effect provides a unique window into the distant universe," said Brenda Frye, one of the galaxy cluster researchers.
The impressive records ofspace telescope generated numerous analyzes that reflect on the formation of the universe, in the same way that they present how they were billions of light years away.

In addition to gravitational lenses, new records they also found other data on galaxies and stars, such as the red giant star Quyllur.
The space telescope has innovative technology that records data using infrared waves. Thus, it penetrates clouds of interstellar dust and records images with rich details.
Because of this, Webb also identified the galaxy "El Anzuelo", in the form of a bright red arc. Such a galaxy is located about 10.6 billion light-years away, according to calculations.
After correcting distortions in the image, the NASA team found that the galaxy "El Anzuelo" is "only" 26,000 light-years in diameter, which represents "a quarter of the size of the Milky Way".
All discoveries demonstrate the high capacity of the telescope to penetrate several layers of galaxies, guaranteeing excellent quality images that will help in studies of the universe.
