00:00Scientists discover a growing weak spot in Earth's magnetic field with potential impacts.

00:05Scientists identified a weak spot in Earth's magnetic field expanding over the South Atlantic,

00:10called the South Atlantic Anomaly.

00:13This area permits increased solar radiation to impact satellites in Earth.

00:17Researchers are examining its effects on navigation, communications and power systems,

00:22potentially revealing shifts in Earth's core and predicting future disruptions.

00:30The South Atlantic Anomaly has expanded, revealing a weaker magnetic field caused by shifts in Earth's molten outer core.

00:37This allows more solar and cosmic radiation to reach the atmosphere, affecting satellites and technology.

00:44Instruments may malfunction and some satellites must temporarily shut down when passing through the SAA to prevent failures.

00:54Earth's magnetic field deflects harmful solar and cosmic radiation, protecting the planet.

00:59When weakened, more radiation enters the atmosphere, potentially disrupting GPS, power grids and radio signals.

01:06This increased exposure can harm living organisms and modern technology, disrupt climate patterns and weaken the ozone layer.

01:16The South Atlantic Anomaly is a growing weak spot where radiation exposure affects satellites, leading to data corruption and system damage.

01:24Radiation poses health risks to astronauts, disrupts communications and shortens satellite lifespans, challenging shielding and backup systems.

01:33Scientists anticipate ongoing changes in Earth's magnetic field, possibly indicating early stages of a reversal.

01:43Partial shifts could disrupt compasses and technology.

01:48The field has weakened by 9% over 200 years, risking global anomalies.

01:53Efforts focus on enhancing satellite shielding, forecasting disturbances and strengthening power grids against radiation exposure.
