The practice of exploring outer space brings with it the possibility of obtaining very important information about the entire universe. universe, including our planet. In this process, it is common to observe foreign bodies that draw a lot of attention, and they may or may not present a danger to us.
Recently, scientists discovered a giant hole in the surface of the Sun, the effects of which could end up affecting the Earth.

The coronal hole present on the surface of the Sun
A coronal hole is nothing more than a region present in the outermost layer of the Sun, the famous solar corona. The properties of the plasma in this region change, since both its density and temperature are at lower levels than elsewhere. With this, the solar corona starts to present a darker tone, giving the impression of the existence of a hole.
The discovery of the hole 20 times larger than Earth
While the Sun was normally rotating, something “strange” caught the attention of observers. A kind of hole entered their field of vision, the size of which drew a lot of attention. According to scientists, the hole is between 18 and 20 times larger than the planet Earth.
Coronal holes are natural phenomena and are part of the Sun's operating system, but impacts significant can arise on Earth, depending on the size of the structure, which is even the case of the hole newly discovered.
How might the hole affect Earth?
Normally, coronal holes release solar winds that travel at incredible speeds, sometimes exceeding 800 km/s. The solar wind from the newly seen hole will release electrically charged particles that have Earth as part of their path. These particles can interfere with terrestrial technological connections, such as satellites, causing interference in services supplied by them.
In addition, they are also capable of causing the appearance of phenomena on the planet, such as auroras, which can be seen in regions of the terrestrial north.
