Dent in Earth’s protective shield is splitting into two as it gets bigger: NASA

NASA has said that earth's protective layer is in danger and a massive chunk of the layer has weakened thus causing a dent in the shield of earth.

National Aeronautics and Space Administration (NASA) has recently confirmed that the protective layer of earth that deflects all the deadly solar radiation is started damaging again. A big spot has been suffered from severe damage due to which NASA observes a dent in Earth’s shields. This phenomenon is named South Atlantic Anomaly (SAA) due to its location which is somewhere over South America and South Atlantic Ocean. Reportedly, SAA has been growing larger and therefore started splitting into two.

Massive dent in Earth’s protective shield and it is getting wider

The sphere of influence has been widening with the size of the anomaly. The reason could be the weaker magnetic field which lets the particle radiation come closer from the Sun to the Earth. That’s not only, it is also affecting the working of the compass and bird’s natural navigation system. If the condition gets worse in the upcoming time then it will also interfere with the computers onboard and with the satellite too. ‘ThunderDome’: WWE Announces Never-seen-before Virtual Experience

NASA has said that earth's protective layer is in danger and a massive chunk of the layer has weakened thus causing a dent in the shield of earth.

For now, we might not be able to see any visible effects of the SAA in our daily life, but it will surely affect the satellite missions.

Dent has been in making for the past 200 years

Previously, magnetic fields were causing trouble when it displaced over the Arctic and shifting the direction of the Earth’s true North. But, recently the European Space Agency (ESA) has reported that the magnetic field of Earth has lost about 9% of its strength over the time period of the past 200 years.

And now, SAA is causing it at an even higher rate of 8% since 1970. But, both of these reasons are not yet confirmed for the bisection. However, as we mentioned above NASA has confirmed that anomaly is surely splitting into two.

The impact of Magnetic Field goes beyond the earth

Even though the reason for the SAA is emerging under the earth but it has been affecting the area even beyond the surface of the earth- especially it has been affecting the region which is home for many satellites.

Many of the space agencies have lower the activities of the satellites in the SAA region in order to protect them. NASA and ESA have been tracking these anomalies for a while now.

  • Is there any indication earth’s weakening field over the last 200 years might be connected to ocean slowing in the same time frame?

    I’m asking because the weaker ocean flow effect of absorbing less CO2 from the air is fairly easy to understand, and well-studied, better all the time, so rising CO2 ppm could easily just be mainly the 95% natural CO2 portion hanging in the air, due to earth’s weakening magnetic field causing less ocean mixing, especially vertically.
