Known as Webb’s first Deep Field, the SMACS-0723 T-Shirt is part of the first imageseries. It is printed in full resolution with authentic, high-quality colors on an organic cotton T-Shirt. Additionally, it features custom JWST detailing on the backside.
SMACS 0723 is a cluster of thousands of galaxies about 4 billion light-years from Earth, including the faintest objects ever observed in the infrared. While it has been observed by Hubble and other telescopes in search of the deep past, NASA’s James Webb Space Telescope has produced the deepest and sharpest infrared image of this distant slice of the universe to date.
This slice of the vast universe contained in the image covers a patch of sky approximately the size of a grain of sand held at arm’s length.
(We like it in white because it highlights the contrast 😎)
