It won't happen again for another 105 years and it's unlikely that anyone on the earth now will be alive for the next one, apart from maybe a few young kids/babies who were too young to see it this time. I was looking at the Iphone/Android apps to time the transit from around the world and reading about this type of technology (Smart phones) not being available just 8 years ago during the last transit. (Ironically the simulations worked, but the app crashed on the day!!) It's amazing how technology has moved on in such a short time. During the transit before that, we were barely able to perform powered flight, now we've been to the moon and people are living in space. So what will technology be like for the next transit of Venus? Maybe people will live longer by then, so our children might see it! Will this forum still be the same, or will there have been another software update by then LOL? I don't think anyone could have imagined the technology we have now a hundred years ago and it's hard to imagine what will develop over the next 100 years. I hope humans will work things out an not make a mess of it!
