Known as Webb’s First Deep Field, this image of galaxy cluster SMACS 0723 is overflowing with detail.

“We are now even more excited for tomorrow’s release of further images and spectra from ESA-contributed instruments, which add another dimension to the Deep Field and the other stunning cosmic targets,” says ESA’s Director of Science, Günther Hasinger. “We are ready to begin our voyage back to the early days of our Universe with this world-class observatory.”

“This is just a first glimpse of what Webb can do," says Macarena Garcia Marin, MIRI ESA Instrument Scientist. "While we are truly in awe today of Webb's first deep field, I can’t help but think of what images and science results are just around the corner in the many years to come!”

This image is among the telescope’s first-full colour images. The full suite will be released Tuesday 12 July, beginning at 16:30 CEST (a leadership address will be aired beforehand, at 15:45 CEST, and a media briefing will follow at 18:30 CEST). Find out how to follow on ESA's channels here.
