The physical properties and elemental abundances of the interstellarmedium in galaxies during cosmic reionization are important for understanding the role of galaxies in this process.We report the AtacamaLarge Millimeter/submillimeterArray detection of an oxygen emission line at awavelength of 88 micrometers froma galaxy at an epoch about 700million years after the Big Bang.The oxygen abundance of this galaxy is estimated at about one-tenth that of the Sun.The nondetection of farinfrared continuum emission indicates a deficiency of interstellar dust in the galaxy.Acarbon emission line at a wavelength of 158micrometers is also not detected, implying an unusually small amount of neutral gas.These properties might allow ionizing photons to escape into the intergalacticmedium.
