May 24 - Next month astronomers across the world will be hoping to get a clear view of the Transit of Venus for the last time in their lives. On June 5 and 6, Venus will pass directly between Earth and the Sun, visible as a small black dot gliding slowly across Sun's face. The Transits occur in a pattern that repeats every 243 years, meaning the next Transit won't appear for another 105 years. Jim Drury has more.

Venus dwarfed by the sun as it pulses across its place in 2004. And events witnessed only six times since 1639. On June the fifth and sixth that transits of Venus a 'cause like going to -- -- lots of astronomers worldwide. It's the last chance they'll get to see this alleged events. The chance to 'cause in two stages I tears apart that what's the another for more than a century. Doctor Maric canola public astronomer at London's royal observatory Greenwich -- I watches every retreats. This animation shows you how it -- of being a success and what people here on earth can expect to see. Saying Venus is meeting between the earth and the sun. -- when it does it's. People on the surface of the we'll see Venus as a tiny black so so it seems against the sun. So look at their feet something like this with this time -- until which is the planet Venus. Moving across the face of this on. And it takes me this several hours to cross one cites another. It's a decent view of the transit into reality depends like nation. The best place is all in Asia and around the Pacific when you should be able to see all of the transit. People in North America should seeing the beginning of the transit just before the sun sex. And people in Europe will got a chance to see the end of the turns it just as the sun is rising loan -- six. It's -- people in western Africa and South America where do you see any of it because it happens at night when the song and it'll -- a -- bit. The transits at the eighteenth and nineteenth century -- crucial to understanding the size of the solar system. Astronomer at mentality to have a comic twist famously ninety was the first directly full cost when the trends -- what -- let's knowing he'd beat date when the trance -- -- 7061. Highly encouraged his successes to collaborate. It's heralded the beginning of the era of international scientific collaboration. According to royal observatory director doctor Rebecca tickets. You -- And -- maritime expeditions being sent across to. A possible bulbs are costly and it's I'm very famously from Britain and 7069. -- the voyage led by captain James cut. Who went time he teaches us that transit and to succeed time. One of business behind me is something that was helpful to some people affected unit Optus. -- date may find it satisfied saying that cat so that they could all be essentially track is saying and sending people to other parts of the world. But you want them to be up to produce results that can be competitive -- -- 21 century technology when -- from the next transits well why don't we it's gonna be full. -- for many it'll be fumbles and an answer tightening diversion. Process and scientific rationale for accepting -- as well I'm one of them. Is in relation to -- not prop effects which was -- sent in the eighteenth century. I missed a lot of time -- instead -- what's causing. Whether it's to do it yeah this is something that's -- I don't condition is also this element of questions back. In 2000 and for the toilet circuitry so hundreds of businesses washing the transit through telescopes a specially to its policies. Staring at the sound with unprotected eyes can cause serious damage. The pyramids in Cairo set is another backdrop for a host of amateur astronomers. All of -- apology make policies and preparing their telescopes at the second site at least once in A lifetime against them teams very what is.
