But the images, which show the distant regions of the universe, will not be available to the public before July 12, the date chosen by NASA to reveal them.
NASA will broadcast the captured images through its official YouTube channel.
NASA Deputy Administrator Pam Milroy said the “first light” images taken by the telescope “impacted me as a scientist, as an engineer, and as a human being.”
The term “first light” generally refers to the first time that a telescope has been used for scientific observations after undergoing tests.
Thomas Zurbuchen, head of science programs at NASA, said during a press conference, Wednesday, that he almost cried when he saw the pictures.
“It’s an emotional moment when you see the universe suddenly release some of its secrets,” he added.
The European Space Agency’s Ariane 5 rocket launched the James Webb Space Telescope into space on Christmas Day 2021.
It took web designers nearly two decades to design, build and then test it before launching.
