A once-in-a-lifetime celestial event will take place Tuesday (June 5) when Venus will cross the sun for the last time this century, and astronomers around the world are in position to catch the show. And now you can be, too.
You don't have to go to the ends of the Earth to catch the transit of Venus. NASA and many research universities, organizations and amateur astronomy groups are offering their own webcasts of the Venus transit and we here at SPACE.com have assembled many of them below for your convenience.
SPACE.com's complete transit of Venus coverage is here.
If watching a Venus transit webcast isn't enough, you can search NASA's Transit of Venus page here for a live event near you.
Here's a look at some of the major Venus transit webcasts currently scheduled:
