Weifeng Web on March 8, I believe like the astronomical knowledge of friends will know, eight planets of the solar line is "water, gold, Earth, fire, wood, Earth, sky and sea. "While this order is row according to the distance from the Sun. That is, the planet closest to the Sun is a star, while Neptune is the most distant one. In this case, shouldn't mercury energy is obtained from the Sun's most powerful. But mercury is always dark inside the eight planets of the solar one, its brightness as worse than the Earth's moon. Also, Mercury's shadow has always been a mystery.
Now, scientists may have brought new insights on this issue. It would also like to thank the Mercury probe Messenger's "die a martyr's death" will enable us to understand that it was as a result of mercury's surface area carbon!
Last May, after the orbiting mercury orbit 4104 times, Messenger: decisive choice of mercury was a crash landing. Lucky is that it brings some of the instruments can be used. Until then, the mainstream view of mercury's face black due to the rich in iron ore. And now, the Messenger spacecraft's neutron spectrometer and x-ray analysis showed that: the reason for this is because there are large amounts of carbon, rather than iron. Also, these carbon cover to the Mercury's time is not very long.
According to the analysis, mercury in the "youth" are very hot, almost all surfaces were covered in molten lava. And after cooling, most mineral and sinks, carbon floating on the surface, is now looks like. Of course, you can also read: precisely because it is too close to the Sun, so it was burnt ... ...
However, it is regrettable that, Messenger could not "live" wait for the solution to this riddle opened the moment, because it had lost contact, will never disappear in the mercury above. X-DORIA iWatch cover
