Once in a Lifetime – City to View Another Rare Astronomical Phenomenon
It seems that Shenzhen is a great place to view space phenomenon as the city is preparing to view Venus transit across the face of the sun tomorrow (06.06.12) . This will be the last Venus transit visible this century and will last for several hours. The next transits will be on December 2117 and December 2125.
A Venus transit occurs when the planet passes directly between the sun and Earth becoming visible across the solar disk. During its transit Venus can be seen from Earth as a small dark disk moving across the surface of the sun. Its transit is similar to a solar eclipse by a moon. Although Venus is 3 ½ times the size of the moon, it appears smaller as it travels across the face of the sun than the moon since its farther away from Earth.
The Venus transit will start at 6:11 am and will last for more than six hours and until 12:48 pm Shenzhen residents can likely see. The Shenzhen Meteorological Observatory will be recording and telecasting the entire Venus transit. Residents who want to learn more about the transit of Venus can visit the Shenzhen Science Museum and the Bao’an Science Museum.
Venus transits are among the rarest of predictable astronomical phenomenon, occurring in a pattern that repeats every 243 years with a pair of transits eight years apart separated by gaps 121 years and 105 years apart. Venus transits have been studied by scientists and were used to gain the first realistic estimates of the sizes of the solar system.
Although the observatory reports that it could be cloudy on Wednesday, the transit can be viewed safely by taking the same precautions used to observe partial phases of a solar eclipse such as viewing through safety filters or projecting it on screens.
