A group led by Fujimoto-san et al have uncovered a primordial galaxy, just 930 million years after the Big Bang (z=6.072). The galaxy is composed of at least 15 dense, star-forming clumps embedded within a rotating disk like a "Cosmic Grape". These clumps, with sizes ranging from 10 to 60 parsecs, dominate 70% of the galaxy's UV light, and are reshaping our understanding of early galactic structure formation. More than 100 hours of joint ALMA and JWST observations were made, amplified by gravitational lensing, making this one of the most studies early galaxies.
