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?公仔箱論壇0 i$ }' o* s5 b# Y, x6 ^2 ?

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.” 1 O( O M4 W$ Q4 HTVBNOW 含有熱門話題,最新最快電視,軟體,遊戲,電影,動漫及日常生活及興趣交流等資訊。 & E" D# Q: f9 T* t5 e) f5.39.217.76[attach]1407406[/attach][attach]1407407[/attach][attach]1407408[/attach][attach]1407409[/attach][attach]1407410[/attach][attach]1407411[/attach][attach]1407412[/attach][attach]1407413[/attach][attach]1407414[/attach]作者: chowold2 時間: 2011-6-24 10:55 AM
