In recent days there has been a lot of talk in different media, with more or less sensationalism, about the weakening of the magnetic field that surrounds the earth and protects it.
Outer space is a rather hostile environment, not only due to the absence of air and pressure or 270 ° C below 0, ultraviolet radiation and cosmic rays, among others, would end life on Earth in a breath.
To protect us from all this, planet Earth is endowed with a magnetic field that surrounds it and that, in addition to making compasses work, repels all these evil radiation.

Well, according to some scientists, this magnetic field that surrounds us is weakening, mainly in the so-called anomaly of the South Atlantic, which covers much of South America and extends to South Africa.
Some researchers believe that the weakening is a sign that the Earth is heading towards a reversal of the poles, that is, that the magnetic north and south poles of the Earth are interchanged, which last happened 780,000 years ago.
Fortunately, it appears that, at the moment, this does not pose a danger to us at the surface level, but it could cause technical failures in the satellites and other ships that fly over the area in low Earth orbit.

But hey, although these things are very intimidating, to start the topic is super complex and we lack enough data and tools to be able to draw conclusions, but we really like this type of news.
I would not worry much because, in addition to the fact that normally in these cases there is nothing to do, when in astronomical matters something imminent is spoken it is a matter of thousands of years and by then, we will all be bald.
