Hubble Finds Oldest Galaxy Yet

The newly discovered star cluster — a hundred times smaller than our own Milky Way — was formed just 480 million years after the 13.7 billion year-old universe itself was born, making it easily the oldest galaxy ever found. As such, it provides astronomers a first-time glimpse at the universe in its R&D phase, when small, sloppy galaxies were being formed out of hot gas, then vanishing shortly after — leaving the skies free for the huge and mature galactic swirls that would come along later. …

“We’re peering into an era where big changes are afoot,” says astronomer and astrophysicist Garth Illingworth of the University of California, Santa Cruz, a co-author of the paper.
