ALMA Distant Galaxies

Caption

Using ALMA, astronomers surveyed an array of normal galaxies seen when the Universe was only 1 billion years old. They detected the glow of ionized carbon filling the space between the stars, indicating these galaxies were fully formed but chemically immature, when compared to similar galaxies a few billion years later. The ALMA data for four of these galaxies is show in relation to objects in the COSMOS field taken with the Hubble Space Telescope
