An imminent astronomical phenomenon is extremely rare

On June 6, 2012, there will be a once-half-a-century average event, providing invaluable data for scientists on the journey to hunt for planets in the vast universe.

>>>Jupiter and Venus together converge

It is a phenomenon of a small black dot that will appear on one side of the sun for several weeks and slowly pass through the solar disk for a few hours. The movement of that small black dot seems insignificant, but this is one of the rarest scenes in astronomy, an event called the "transit" of Venus.

If you ignore this time, you have to wait until 2117 to see it again. The last time Venus went through the sun was from the 1600s.

The nearest neighbor of the Earth and night still stands in line with Jupiter, which will provide scientists with important data in studying the worlds of orbiting distant orbits.

In the past two centuries, there have been 4 times "Venus" in transit through the sun.

'This transit is very special because this will be the last time in our life we ​​have the opportunity to collect data about a particular planet like Venus ,' said scientist David Crisp working at the Lab. Jet engine test says.

Venus, with its sparkling beauty in the night sky and its connection to Roman love goddesses, is actually a world that is not pleasant. The surface temperature of 460 degrees Celsius and the dense atmosphere of carbon dioxide burned or crushed all spacecraft that landed here. The surface of Venus is covered by dense sulfuric acid clouds.

In the past, Venus was thought to be a brother to Earth because of the size and orbit around the sun, but it seems that Kim is more like hell.

However, in terms of research, the rare transit of Venus will provide important data to help astronomers test the techniques they are developing to study the atmosphere of exoplanets. - worlds around another sun - and found places with life-supporting factors like oxygen and steam.
