The terrifying silence of the Sun.

The Sun can sweep through the Earth with strong winds that interfere with communications, affect air traffic and destroy wiring even if it is in a static state for a 11-year period of the Calendar God.

Observers have used the traditional method based on the amount of black points on the Sun's surface to estimate its activities. In one cycle, the maximum number of black points in the state called the sun maximum then declines to reach the minimum state.

Sunspots, which can be seen from the Earth by telescopes, are dark spaces, which are actually the places where powerful magnetic activity takes place on the surface of the Sun.

The Sun with black holes contains a strong magnetic energy source.

At the highest level, the maximum state, the sun's bright spots (fragments of the sun filled with electrical charge) are harsh and geomagnetic storms release an amount of energy into space, colliding with magnetic Earth's protective field, breaking satellites, interfering with communications and causing aurora phenomenon.

But scientists at the US National Center for Atmospheric Research and the University of Michigan found that the Earth was bombarded by solar winds in 2008 despite being in an unusually quiet period .

' The Sun will continue to surprise us, ' said Sarah Gibson of High Altitude Observatory. ' The solar wind can sweep over the Earth like a fire horse even if almost no black holes appear on the surface of the Sun. '

Scientists had previously thought that large currents of energy would not appear when the solar cycle gradually reached the minimum point.

Gibson and his team of scientists from NOAA and NASA, compared the measured data at the time of the current solar minimum in 2008 with the data of the minimum solar cycle. before 1996.

Although at the current minimum period, the Sun has a number of black holes less than any minimum during the past 75 years but it is strange that the Sun's impact on the outermost radiation belt of the Earth 3 times stronger than in 1996.

The work published in the latest issue of the Journal of Geophysical Research shows that the occurrence of high-speed winds during the Sun's minimum cycle is now related to structure. The current structure of the Sun.

When the Sun was in its minimum period in 1996, the Sun only glided across the Earth, with weak energy streams including chaotic magnetic fields.But on the contrary, in 2008, even in the quietest state, even the quietest in the past 100 years, the Sun exerted three times more force on Earth with powerful energies.

Scientists have sought to explain this phenomenon. They claim that in the past few years black holes have gradually decreased in the solar cycle, but large black holes still exist, although weaker on the Sun's surface in an area close to its orbit. High-velocity winds out of black holes flooded the Earth during 55% of the 2008 study time, much larger than the 31% of the previous period in 1996.

Research shows that a single energy stream of charged molecules can last 7 to 10 days.

Janet Kozyra of the University of Michigan said: ' New observations last year are changing our understanding of two issues: how quiet the Sun's time periods affect the Earth and so on. and why this effect changes between cycles '.

The Sun is currently the quietest state in nearly 100 years. Many scientists believe this is a sign that the Earth may be facing a new Little Ice Age similar to the Maunder Period .

The Maunder Minimum period lasted from 1645 to 1715, associated with unusual solar storms. It corresponds to a very quiet period of black marks - astronomers at that time recorded only 50 sunspots over a period of 30 years.

Some believe that the inactivity of the Sun causes the Earth to experience a Little Ice Age to reduce the warming of the Earth.
