The formation of galaxies

The large galaxy at the front of the image is LEDA 2046648, and it looks just over a billion years back in time, while most of the others are even further away, and therefore look further back in time. Credit: ESA/Webb, NASA & CSA, A. Martel

The image shows a deep image of the Pandora galaxy cluster, or Abell 2744, using data from NASA's James Webb Space Telescope. Following the image, an international team led by Penn State University researchers confirmed the distance of these ancient galaxies and inferred their properties using new spectroscopic data James B. Telescope - Information on light emitted across the entire electromagnetic spectrum. About 33 billion light-years away, these particularly distant galaxies provide insights into how primordial galaxies could have formed.

Unlike other distant galaxies that have been discovered, which appear as small red dots, the two new galaxies are large and have an unusual appearance - one resembling a peanut and the other a fluffy ball, indicating the diversity of galaxies in the early universe. According to the speed and direction of their distance, today they are beyond our line of sight
The image shows the most distant galaxy ever discovered by the Hubble Space Telescope's Deep Space Survey System. The field of view of the survey includes tens of thousands of galaxies throughout all time. The distant galaxy GN-z11 appears to us as it was 400 million years after the Big Bang, 3% of its current age. Credit: NASA, ESA, and P. Oesch (Yale University)
