Webb’s first stunning view was released by President Joe Biden on July 11 and it is “the deepest and sharpest infrared image of the distant universe to date,” according to NASA. Webb’s first image shows SMACS 0723, where a massive group of galaxy clusters act as a magnifying glass for the objects behind them.
” One feature of interest in the deep field has been nicknamed the Sparkler galaxy because it appears to be surrounded by red and yellow sparkling dots. The galaxy is located nine billion light-years away. The sparkles could either be young clusters where stars were actively forming just three billion years after the Big Bang, or they might be ancient globular clusters of stars from the early days of the galaxy’s formation.
