The solar activity is cyclical and when it reaches its maximum its magnetic field changes. Then, the positive pole of the Sun becomes negative and vice versa. This fact has led researchers to check that the number of dust particles arriving from the universe has tripled.

In fact, the new cycle began in 2001, and before it, these particles removed the areas of the Sun outward. Now, on the contrary, it attracts them and, consequently, they announce that in the next decade the particles of galactic dust will be much more abundant. However, researchers have stated that until 2006 they will continue to carry out studies to ensure data.
