Astronomers believe that something strange happens in the sun, especially when it enters the period of the "lower cycle" of the solar cycle, in which decreases the number of sunspots while increasing the proportion of cosmic radiation. According to the Bloomberg report, scientists say that the radiation rate in the lower cycle has increased unprecedented since the beginning of the space age
During the regular 11-year solar cycle, sunspots are thinned and the eruptions diminish. At the height of solar activity, the sun's magnetic field acts on the protection of planets, and
Nathan Schwadron, professor of space physics at the University of New Hampshire, believes that "we are going through a very strange solar cycle and continue to show signs of worsening. "
Astronauts and those who can travel in space, including manned flights to Mars, are examples.
Research has shown that exposure to cosmic radiation in all its forms increases the risks to the health of astronauts. , They become susceptible to heart disease and cancer
Scientists believe that the lower solar cycle, coupled with a weakening of the solar magnetic field, would cause an increase in radiation rate of about 30 percent more than of habit, 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, raising concerns among time scientists. This is not unusual because solar activity can decrease during an 11-year cycle Since 2008, the sun has completed 24 cycles up to now, but they warned that the current situation could lead at the entrance of the Earth in a small ice age.
The number of spots reached its peak during the 14th session of the Sun. ] You can also read the news in the source of the new morning newspaper
