Turn Around, Bright Eyes

There's been a lot of press about the "Transit of Venus"-- that astronomical event, occurring even as I type, where Venus is actually visible to we Earthlings as a tiny dot on the sun as its orbit crosses ours. Much has been made of the fact that the next transit is not for 105 years (so see it while you can, folks!), but some of the coverage has focused on the practical aspects of viewing such a rare spectacle, reminding us that it is dangerous to look directly into the sun; in fact, I actually heard these words on the radio this morning, you can destroy your vision instantly... Yikes!

When I was 7 there was a total eclipse of the sun that was visible across North America. Thinking back, it seems like that was all anyone talked about for days. Both at school and at home we were warned again and again not to look right at it. At the same time, it seemed like everyone had a trick for being able to watch the eclipse without damaging your eyesight.

When the time came, my dad poked a hole in a sheet of paper and held it in the direct sunlight streaming through our living room window with another piece of paper below it. The idea was that the light shining through the pinhole would be eclipsed as the sun was. I don't think it worked, because I also remember watching the eclipse on TV.

Back then, I imagined that if we looked our eyes would ignite and burn away, and we would be left blind, but with that final image of that sun's corona dancing around the shadow of the moon burned into our brains forever.
