🌍Earth's magnetic field shields us from deadly cosmic radiation
⚠️The South Atlantic anomaly is a region experiencing dangerous levels of radiation
💥Life on Earth is vulnerable without the protective magnetosphere
🔬NASA scientists are monitoring the impact on technology
🧬Increased radiation may lead to higher rates of cancer and DNA mutations
What is the South Atlantic anomaly?
—The South Atlantic anomaly is a region off the coast of Brazil where Earth's magnetic field is weakening, leading to dangerous levels of radiation.
How does the weakening magnetic field affect technology?
—The weakening magnetic field can cause total failures of communication in spacecraft and permanently damage satellites when they pass over the anomaly.
What are the consequences of increased radiation on Earth?
—Increased radiation can lead to higher rates of cancer among populations and cause DNA mutations in all forms of life.
What does ancient pottery tell us about the Earth's magnetic field?
—Ancient pottery contains magnetic particles that align with Earth's magnetic field when fired, providing a record of the field's strength at the time.
What happened to Mars' magnetic field?
—Mars lost its magnetic field, resulting in the stripping away of its atmosphere, oceans vaporizing, and the extinction of any primitive life forms.
