Scientists have discovered on the Sun Showers

Scientists found that the rains do occur even in the sun. They, of course, differ significantly from normal, but its characteristics still resemble them.
It should be noted that due to this phenomenon can explain why the solar corona has a higher temperature than the inner layers, wrote Science.YoRead.ru.
«coronal rain” is a high density of nodes, which differ relatively low temperature is several tens of thousands of degrees, that the Sun is not much. A mechanism of how it happens, very similar to regular rain.
heated to enormous temperatures of the plasma rises to the upper layers of the solar atmosphere, which cools down considerably and poured back with great speed, which more than 100 km / h. Currently, there are two theories to explain this phenomenon. The first is that this process is influenced by magnetic field that accelerates the plasma. For the second hypothesis, the influence of seismic processes.
Japanese scientists have built a computer model of the sun in order to understand how there is a “coronal rain.” As a result, they concluded that the closer to reality, the second theory, and emissions of plasma in the upper layers of the Sun due to the fact that at the stellar surface from time to time there are seismic processes.
