Every so often something in space happens that sends excitement throughout Earth.  Back in the 80's it was Haley's Comet (which is something you can only see every 75 years).  Every time we have a lunar or solar eclipse people get excited.  However, something is happening today that is a once in a lifetime event. 

Venus will cross the sun for a once in a lifetime event. According to Cosmic Log on MSNBC:

Venus comes between Earth and the sun five times in the course of every eight years, but because of the inclination of the planets' orbits, Venus usually misses passing over the sun's disk, as seen from Earth. In fact, that passing-over phenomenon occurs only twice in the typical person's lifetime. Two transits occur eight years apart, but each pair is separated by either 105.5 years or 121.5 years. We had a Venus transit in 2004, and we're having another one today. The next one won't come until 2117. So if you're into rare sky phenomena, today is as good as it gets.

If you plan on viewing the awesomeness tonight please, please, please make sure you view it in a safe matter which means you cannot stare directly at the sun for a long period of time, it can damage your retinas.  Instead make sure you have the proper equipment to view the sun, for ideas click here,  or view Venus as it passes over the sun online here.

So get your cameras ready and your protective eye gear and take pictures of this scientific wonder.  When you snap your pictures tonight hop on this post and upload them to the form below.  We will post all the awesome pictures we get starting tomorrow.  So send them in!
