CALIFORNIA: Stargazers around the world watched a very rare event in the skies above them this week. The planet Venus passed in front of the sun for the first time since 1882, appearing as a small black disc that took six hours to move across it. But people had to be very careful when looking at it as even a brief look at the Sun can damage your eyesight. Many people went to special viewings where the event was shown using special equipment to keep it safe. Others chose one of the safest ways to watch, using websites like this one that linked to live cameras following the event. The next transit of Venus will happen in 2012, with the one after that not until 2117.
