Astronomers trace the evolution of the first galaxies in the universe

A systematic search for the first bright galaxies to form in the early universe has revealed a dramatic jump in the number of such galaxies around 13 billion years ago. These observations of the earliest stages in the evolution of galaxies provide new evidence for the hierarchical theory of galaxy formation--the idea that large galaxies built up over time as smaller galaxies collided and merged.
