The Venus Transit
Now we all have something in common with the people of 1882, when they had an opportunity to gaze into the sky and watch Venus cross the sun. Of course they didn’t have amazing visuals like this to see the event in high definition.
This won’t happen again for 105 years, which means our unborn baby probably won’t see this in its lifetime, unless medical science allows for a longer average lifespan. It’s hard to imagine what the earth will look like the next time humanity observes this phenomenon.
