You could see something today that most people don't get to see in their entire lifetime. Something Edmond Halley (of Halley's Comet fame) predicted and knew he himself would not live to see.
An alert reader notified me yesterday that today, June 5, is when Venus passes directly between me and the sun. Standing in North America, I should be able to see Venus as a small dot gliding slowly across the face of the sun around 6 pm - sunset.......
The next transit will be in December of 2117.
Tonight you can watch it live on Slooh.com and preserve your eyesight while doing so. But of course then it won't feel very realistic, it will feel like a TV show and who needs more of those?
