美國天降「火球」直穿民宅屋頂，專家鑑定揭係45.6億年隕石碎片，比地球更古老。
A fireball, or a bright meteorite, was seen across the southeastern United States on Thursday and later exploded over Georgia, creating booms heard by residents in the area, according to NASA.

隕石碎片擊穿民宅屋頂留坑洞
綜合外媒報導，美國喬治亞州上空驚現「火球」劃破夜空，專家經分析確認是隕石碎片。事發於去年6月26日，隕石碎片墜落在亞特蘭大（Atlanta）附近，不僅擊穿當地一間民宅屋頂，更貫穿通風管道、絕緣材料及天花板，最終在地板上留下約1.5釐米深的撞擊坑洞。

碎片源自小行星帶 超音速墜地威力驚人
經喬治亞大學地質學教授哈里斯（Scott Harris）指出，這塊隕石碎片源自火星與木星之間的小行星帶，進入大氣層時短暫突破音障，以超音速飛行，令不少民眾目睹「火球」一幕。由於撞擊力強，導致部分碎片完全粉碎，「就像有人拿大錘子敲過一樣。」

比地球更古老 隕石逾45億年歷史
哈里斯鑑定後發現，這塊來自太空的岩石歷史可追溯至45.6億年前，「可追溯到45.6億年前形成的原始材料」，略早於各大行星形成之前，比地球年齡還要早2000萬年。

科學家倡研防撞技術 動能撞擊器或成關鍵
哈里斯指出，雖然這種小型隕石不足以構成威脅，但科學家仍希望藉此研究隕石動力學，評估未來潛在的撞擊風險，並開發避免碰撞的技術，例如利用動能撞擊器令小行星稍微偏移，「如果你能夠移動一顆朝著我們飛來的小行星，而且移動得夠多，就能讓它避開我們所有人」。
