Last week, the National Aeronautics and Space Administration (NASA) discovered a black region on the Sun. It looks like someone has made a hole in our star.
What is known
This is not about a hole in common understanding. This is just a region on the Sun that is much cooler than the rest of the star. Because of this, it has a black color.
After its discovery, the US National Oceanic and Atmospheric Administration (NOAA) warned of geomagnetic storms. They are expected to be assigned a G1 or G2 index on a scale up to G5, where G5 are extreme strong storms and G1 are weak ones.
At the same time, scientists recognize that the hole has a gigantic size. Its diameter is 300,000-400,000 km. This is about 20-30 planets such as the Earth, lined up in a row. The presence of such a zone on the Sun does not affect life on Earth, but it looks impressive.
