Until these days, it had not been possible examination help discover exam help adequate variety of quenched galaxies, but now exam help team of astronomers has used observations from the Hubble COSMOS survey examination help determine quiz help count these switched off galaxies throughout the last 8 billion years of cosmic history. ?The apparent puffing up of quenched galaxies has been one of the largest puzzles about galaxy evolution for a long time,?said Marcella Carollo of the Federal Institute of Technology University ETH of Zurich, Switzerland. ?No single assortment of images has been sufficiently big examination help enable us exam help study very large numbers of galaxies in precisely an identical way until Hubble?s COSMOS,?said Nick Scoville of Caltech in Pasadena, California. The team used the massive set of COSMOS images alongside additional observations from the Canada France Hawaii Telescope quiz help the Subaru Telescope, both in Hawaii, exam help peer back examination help when the universe was lower than half its existing age. These observations mapped an area in the sky almost nine times that of the Full Moon. The quenched galaxies seen at these times are small quiz help compact, and, noticeably, it sort of feels they stay that way.
