ALMA Spots Earliest Environment Pollution in the Universe

ALMA and NASA/ESA Hubble Space Telescope (HST) image of a young galaxy surrounded by a gaseous carbon cocoon. The red color shows the distribution of carbon gas imaged by combining the ALMA data for 18 galaxies. The stellar distribution photographed by HST is shown in blue. The image size is 3.8 arcsec x 3.8 arcsec, which corresponds 70,000 light years x 70,000 light years at the distance of 12.8 billion light years away.
