Transit of Venus June 2012 has dazzled the world. It is the biggest celestial event of our times. NASA has made arrangements for its live streaming. You can watch it on their website
Venus transit is finally here. It is visible in much of Asia right now and people are excited with the prospects of being able to watch it. They believe they will become part of the history by watching a celestial incident that happens in more than a century. The last time it took place was in the year 2004 but the next Venus transit will happen only in the year 2117.
The transit is underway for more than three hours now and for another three and half hours it will be visible in many parts of Asia and Europe. When the transit of Venus happened in the year 2004, not many people were aware about it as there was not much awareness related to celestial incidents at that time. But now with online media becoming part of our life, it has become a general talking point. When you are able to watch the Venus crossing the Sun, it will appear as a tiny black dot on the mighty Sun’s surface.
In India the transit of Venus will be visible for several hours. Right now it is visible and will continue to be visible till 10:20 AM. C.B. Devgun, a space enthusiast says, “The occurrence will be visible from anywhere in India. The greatest transit, when the black dot of venus can be observed at the innermost point of the solar disc, will occur around 7:02 a.m. It will be visible in northern India between sunrise and 10:20 a.m.”. but before you get excited and head out of your home, grab a solar eclipse glass as sun will damage your eyes if you try to watch it.
It is not advisable to watch the Sun directly. It should only be watched directly when filters specially designed to protect your eyes are used. Most of these filters have a thin layer of chromium alloy or aluminum deposited on their surfaces that attenuates both visible and near-infrared radiation. Given the fact that many solar filters have been found to be of bad quality, you should ensure that these are manufactured by government approved suppliers. A safe solar filter should transmit less than 0.003% (density ~4.5) of visible light and no more than 0.5% (density ~2.3) of the near-infrared radiation from 780–1400 nm. So take these precautions and enjoy a safe watching of transit of Venus. Watch it Live on NASA
