NASA's Solar Dynamics Observatory (SDO) space telescope has captured images of a giant hole in the Sun's outer layer. The structure is 800,000 kilometers in diameter.
This area is 60 times larger than the surface of the Earth. The explosion is suspected to have occurred on January 25-26 and this Friday experts have said that the solar wind could reach Earth this Friday, but without any negative impact, as it is estimated to be of class G1, out of 5 such.
These holes are caused in certain regions of the sun, as the magnetic field opens, they "release solar material at high speeds in a stream of solar wind." This means that these areas are not connected to magnetic fields of a turbulent nature, like sunspots, and allow heat to flow through space, writes A2 CNN.
Because of their magnetism, these holes are cooler and are captured as dark spots by the Solar Dynamics Observatory (SDO) telescope. This telescope has instruments such as the Extreme Ultraviolet Variability Experiment, which measures radiation, and the Atmospheric Imaging Array, dedicated to taking images in the ultraviolet bands.
