Caption

Artist impression of a progenitor of galaxies like the Milky Way, seen when the universe was only 1.5 billion years old. New observations reveal that these galaxies are surrounded by massive halos of hydrogen gas. This material relates to a paper that appeared in the March 24, 2017 issue of Science, published by AAAS. The paper, by M. Neeleman at University of California, Santa Cruz in Santa Cruz, CA, and colleagues was titled, "[C II] 158-μm emission from the host galaxies of damped Lyman-alpha systems."
