Abell 2147 is a galaxy cluster in the Abell catalogue.〔(ABELL 2147 ), Archive of Chandra Cluster Entropy Tables, Michigan State University, retrieved 2012-03-31.〕 It is located within the core of the Hercules Superclusters, within Serpens Caput, approximately two degrees south southwest of the Hercules Cluster (AGC 2151). It is possible that Abell 2147 is actually part of the Hercules Cluster considering that it shares the same redshift of 550 million light years.〔(Notes on Obscure Galaxy Clusters ), San Francisco Amateur Astronomers, retrieved 2012-03-31.〕 This galaxy cluster contains mostly faint, small and scattered galaxies.〔 ==See also== * Abell catalogue * List of Abell clusters * X-ray astronomy 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Abell 2147」の詳細全文を読む スポンサード リンク
