恆星最快今年大爆炸 將有「兩個太陽」

牙`蔚

人類今年有望目睹恆星爆炸成超新星，將黑夜化為白晝的宇宙異象。地球人不僅可在「前座」觀賞這場星光秀，這顆超新星的亮度將有如天空出現兩個太陽，時間短則一周，長則數周。

英國每日郵報報導，目前天空最亮的紅巨星「參宿四」（Betelgeuse）已在垂死邊緣，根據21日的一分報告，參宿四最快今年內就會爆炸。這個位於獵戶座、距地球640光年的紅巨星，爆炸的光亮可將黑夜變成白天。參宿四的目前的亮度於夜空排第九。

目前唯一難確定的是參宿四殞落的時間。澳洲南昆士蘭大學物理學傢卡特說，最快可能2012年前爆炸，也可能很久以後。

卡特說，參宿四的核心燃料將告罄。目前燃料仍撐著它的亮度，一旦燃料用盡，星體即會塌陷，且速度極快。最後星體爆炸，化為光亮，這個光亮可維持一、兩周到數周，數月後消退，杳無蹤跡。

網路上已出現新的末日論，將參宿四殞落與瑪雅曆法隻列到2012年相提並論，宣稱這顆星球爆炸將導致世界末日。專傢斥為無稽之談，指出這顆星球距離地球很遠，就算爆炸也不會對人類造成傷害，爆炸時會有許多所謂的「微子」如雨般降下，但它會穿過人體和地球，不會遺留傷害。
