On March 29, 2006, a total solar eclipse occurred as the moon moved directly between the earth and the sun. The moon's shadow fell on the earth, first darkening the eastern tip of Brazil, and then moved across the Atlantic Ocean to make landfall in Ghana, Africa. It continued moving northeast through Nigeria, Niger, Libya, Egypt, across the Mediterranean and into Turkey, where an Exploratorium team was waiting.
