A total eclipse — where the moon completely blots out the sun, where day turns to night, where solar flares ring the moon's shadow like a crown of flame — that's the eclipse everybody wants to see, the alpha eclipse that eclipses all the other eclipses. Everybody knows this (me included), until I saw this ... Yes, it looks like a cross-eyed space alien staring out of the darkness, so to make things clearer, let me add one more "eye," like this ... What are we looking at? On Aug. 20, 2013, NASA's robot Curiosity was sitting on a Martian plain and one of its cameras looked up at the sky and saw the little moon Phobos passing across the face of the sun. Curiosity's camera snapped a picture every three seconds. So what you see here is a sequence. The moon appears on the right side of the sun, moves center, exits left, a passage that took about 37 seconds. Had you been on Mars that day, this (NASA animated its photos)
