在非洲幅員廣大,橫跨多國的撒哈拉沙漠,有一處只能從外太空才能看見的奇觀─撒哈拉之眼(Eye of the Sahara),在衛星空拍圖上,這個看來巨大又神祕的同心圓,就像是麥田事件般令人感到困惑,至今仍無科學家提出成形的原因。為什麼地球上會出現這般專屬外星人欣賞的奇觀?tvb now,tvbnow,bttvb/ G7 i, b+ ?+ A6 v$ _

曾經有科學家提出是因為隕石撞地球,才會有這般神祕地形,但也有人說,是因為撒哈拉沙漠在侵蝕作用及陸地抬升,兩者交會造成的地形落差,才造成這般巨大的幾何圖形!近年科學家又發現同樣在撒哈拉沙漠,位於東部的國家蘇丹、利比亞及埃及交界處,也有小型的撒哈拉之眼現蹤跡,留給人們很多想像空間。5.39.217.77/ R. {$ n4 x7 D

Since the beginning of space missions, the Earth’s bulls-eye caught the interest of astronauts in the otherwise featureless Sahara Desert. Over the years, it has become a landmark for astronauts. At first, the circular pattern was thought to have been a meteorite impact, but now the 31 mile wide bulls-eye, called the Richat Structure, is believed to be uplifted rock, a circular anticline, laid bare by erosion. Some people call this bulls-eye in the Sahara the “Eye of Africa.” 6 Q$ [4 Q, S& c6 Y& g h. o& ]# E2 p5 B! j( L/ v8 F; P
