Discovered in 1952 at the Crimean Astrophysical Observatory using a 25-inch Schmidt-Cassegrain telescope, it is difficult to observe due to its extremely low brightness. The nebulous area is fairly large with an almost spherical shell and filamentary structure.〔(【引用サイトリンク】url=http://vizier.u-strasbg.fr/viz-bin/VizieR-5?-ref=VIZ52b391ab3a6e&-out.add=.&-source=VII/20/catalog&recno=240 )〕 The remnant has an apparent diameter of approximately 3 degrees, an estimated distance of approximately 3000 (±350) light-years, and an age of approximately 40,000 years.〔(【引用サイトリンク】url=http://apod.nasa.gov/apod/ap121009.html )〕 It is believed that after its stellar explosion a rapidly spinning neutron star known as pulsar PSR J0538+2817 was left behind in the nebula core, emitting a strong radio signal.〔(【引用サイトリンク】url=http://simbad.u-strasbg.fr/simbad/sim-id?Ident=SIM%20147#lab_annotations )〕 == References == 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「Simeis 147」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
