On Wednesday June 6th, an exceptional astronomical event will take place. As seen from Earth, the planet Venus will pass in a straight line between Earth and the Sun. As a result of that, an observer on Earth can see the planet Venus 'transiting' the Sun disk. When you are looking at the Sun using special equipment (*never* look without any protection straight to the sun !), you can see a black circle slowly passing over the Sun.
The last time this event took place, was 8 years ago. However, it will take another 100 years, on 2117 Dec 11th and 2125 Dec 08th, for anyone to be able to observe this transit again.
For observers in Belgium, only the last part of the 7 hours during spectacle will be visible in the morning of June 6th, and this from 5:21 (sun rise) up till 6:55, when the planet's silhouette will leave the sun's disk. This event is an ideal opportunity to have a look at this through professional equipment, several observatories will be open to the public to give you an opportunity to look at the Venus transit.
