Sentences with phrase «galaxies over cosmic time»
Previous infrared missions, from IRAS to Herschel, have revealed a great deal about the obscured... ▽ More Measurements in the infrared wavelength domain allow us to assess directly the physical state and energy balance of cool matter in space, thus enabling the detailed study of the various processes that govern the formation and early evolution of stars and planetary systems in galaxies over cosmic time.

«Measuring the oxygen content of galaxies over cosmic time is one of the key methods we have for understanding how galaxies grow, as well as how they spew out gas into the intergalactic medium,» she said.
Dr. Jean Brodie, from the University of California at Santa Cruz, will trace the formation and evolution of galaxies over cosmic time, making use of some «astronomical fossils» called globular star clusters, that are bright beacons tracing all the mergers and acquisitions that have assembled into present day galaxies.
