New observations performed with the Inamori Magellan Areal Camera and Spectrograph (IMACS) on the Magellan telescope of the Las Campanas Observatory have made it possible to determine the average age and the chemical composition of the stellar populations in the galaxies belonging to the Universe of 7 billion years ago. Through these observations it is possible to study how these physical properties changed over time and identify the ways in which the galaxies may have evolved through to the present Universe.
