On Monday, US President Joe Biden unveiled another image produced by Webb, galaxy cluster SMACS 0723, which is filled with thousands of galaxies, including the faintest objects ever observed in the infrared.

"These images, including the deepest view of our universe that has ever been taken, show us how Webb will help to uncover the answers to questions we don't even yet know to ask; questions that will help us better understand our universe and humanity's place within it," Nelson said.

The release of Webb's first images and spectra kicks off the beginning of Webb's science operations, where astronomers around the world will have their chance to observe anything from objects within the solar system to the early universe using Webb's four instruments, according to NASA.
