Are you awake for it?
Today - RIGHT NOW - you have the chance to see a very rare natural phenomenon occuring on our skies. They call it the passage of Venus. What happens is that Venus passes between the sun and the earth. You can see the live webcast here. Oslo is one of the places in the world where you can see this best, but there are webcasts from several different cities in Norway, linked from here. The next passage is scheduled in eight years, but the last one happened 122 years ago. Track the transit of Venus here!
I appears that the passage of Venus plays a role in Mayan mythology. And of course there is a very different kind of Venus pasage, this one including Adonis.
