Astronomers believe that something strange happens in the sun, especially since it enters the period of the "lower cycle" of the solar cycle, in which the decrease in the number sunspot increases the proportion of cosmic radiation.
Scientists say that the radiation rate in the lower cycle has increased unparalleled since the beginning of the space age, according to the Bloomberg report.
During the regular solar cycle of 11 years, sunspots decrease, solar flares decrease and the magnetic field of the sun falls. At the height of solar activity, the magnetic field of the sun protects the planets, including including our planet, charged cosmic rays. "We are going through a very strange solar cycle and continue to show signs of worsening," said Nathan Schwadron, a professor of space physics at the University of New Hampshire.
However, scientists believe that Earth will not be much affected by this, where the effect will include astronauts and those who could travel in space, especially manned flights to Mars, for example .
Exposure to cosmic radiation (in all its forms) increases the health risks of astronauts who may be suffering from heart disease and cancer at some point in their lives.
Scientists believe that the lower solar cycle, coupled with weak solar sun field, will cause an increase in radiation rate of about 30 percent than usual, but the question of The magnitude of the problem of cosmic radiation remains open.
Two years ago, NASA published an image of the sun showing the disappearance of sunspots from its surface, which caused alarm among meteorologists. Solar activity may decline during an 11-year cycle Since 2008, the sun has completed 24 cycles up to now, but they have warned that the current situation could lead to the entry of the Earth Mini ice.
The number of spots culminated in the fourteenth cycle of the sun, in 1906.
