    Looking straightly at the sun without protection during the transit of Venus will badly damage your eyes, but can that happen if you are standing outside facing away from the sun, or even driving? I don't plan on going outside, rather I'm concerned about someone who might drive home while the event is taking place. Where I am in America the transit will occur this evening. We haven't known anything about it until yesterday.

    The transit of Venus has only a trivial effect (reduction) on the brightness of the observed sun. Being outside during the transit is no more dangerous than being outside on an ordinary sunny day.

    Thank you. The person whom I mentioned came home before the transit started, so I didn't have to worry about it anyway.

    If you have eclipse glasses on (which are safe to look at the sun with) you could barely notice Venus' black dot on the disk. It has no effect on earth, other than exciting astronomers. Unless it's raining, like it is here.

    Are you saying that although eclipse glasses offer proper protection to watch Venus' transit those prevent you from seeing it? Why, then, does NASA include eclipse glasses in their recommendations for viewing the transit?

    No, I'm saying that eclipse glasses allow you to see it. It's just that Venus' disk is fairly small on the surface of the sun, so you have to look carefully to notice it. I did see it today using the eclipse glasses, in fact.

    The disc of the Sun is very small in the sky. It just looks really bright and big. But through eclipse glasses, you can see just how far away and small the Sun looks. The images you see in the media are from telescopes/ filter/ other tricks.

    You can also make a pinhole viewing device by punching a tiny hole in a piece of cardboard and hovering it over another piece of paper. The image would be even tinier, though. And mirror-image.
    It is by will alone I set my mind in motion.

    Well, I missed it - clouds and sleeping in. I'll just have to hope there is a longevity drug found in the next year or two so I can catch the next one.

    Thank you, MeteorWayne and pyoko. John Galt, I have missed it too due to a lack of proper viewing equipment, but seen some of it on NASA's website. I'm sorry to tell you that you can't count on being here in the twenty-second century. At least we know what it looks like.

    I was lucky to see this one through a hole in the clouds, as well as the one 8 years ago, where I had several hours to watch.

    I used the dark glass from a welder's helmet to view the small black dot of venus in the high northern latitudes of the sun(clouds here too, so only a few minutes)
