The James Webb Space Telescope team released an image of a wide field filled with many

LEDA 2046648 is located at the bottom of the picture.This is a spiral galaxy, the light from which has traveled to the Earth for more than a billion years. The difference in size between this galaxy and others is due not to physical differences, but to distance: small and fuzzy structures are located even further from the solar system.
The European Space Agency notes thatone of Webb's main scientific goals is to observe distant and ancient galaxies. Comparing these galactic fossils to today's galaxies will help astronomers understand how they grew and formed the structures we see in the universe today.

To take full advantage of the potentialWebb for Galaxy Archeology, astronomers and engineers must first calibrate the telescope's instruments and systems. Each of the instruments contains a maze of mirrors and other optical elements that redirect and focus the starlight collected by Webb's primary mirror.
Beautiful shot LEDA 2046648 - almost accidental,it was made in preparation for the commissioning of the Webb Near-Infrared Imaging and Slitless Spectrograph (NIRISS).
