'Time machine' reveals hidden structures in the universe's first galaxies

SMRTR summary

Astronomers used ALMA to observe 39 early galaxies from 1 billion years post-Big Bang. The CRISTAL survey revealed hidden structures, including massive star-forming clumps and extended cold gas. Two galaxies, CRISTAL-13 and CRISTAL-10, stood out for their unique features. This research offers insights into galaxy evolution and how early chaotic galaxies became well-ordered structures like the Milky Way.
