＜p＞KIC 8462852 was thought to be a non-descript star. Then suddenly it dimmed for a day! And later once again! Next it was shown to have gradually reduced its light strength for the last century. What causes this unexpected, far out of the ordinary behavior? What obscures the light from this star? Birds? Planes? Superman? Or perchance comets or the debris of a planet smashed up by Superman? Or - nobelieves it - a colossal artificial structure built Superman's kin? None of the above. It is due to the complete ionization of helium atoms.＜/p＞画面が切り替わりますので、しばらくお待ち下さい。 ※ご購入は、楽天kobo商品ページからお願いします。※切り替わらない場合は、こちら をクリックして下さい。 ※このページからは注文できません。
