Researchers have discovered about 80 young galaxies in the early universe about 1.2 billion years after the Big Bang. They made detailed analyses of imaging data by the Hubble Space Telescope. Among them, 8 galaxies show double-component structures and the remaining 46 seem to have elongated structures. These results strongly suggest that galactic clumps in the young universe grow to become large galaxies through mergers.
