• Hidden geomagnetic reversals found in Earth’s magnetic history

    ByRishika Yadav

    Earth’s magnetic field may have experienced more polarity reversals than currently recorded, according to a new study using statistical modeling. Researchers found anomalies in the geomagnetic reversal frequency, suggesting that some reversals remain undetected. Incorporating recently discovered reversals from Ethiopian flood basalts into the dataset revealed hidden patterns that could refine our understanding of Earth’s magnetic history.

  • Low-velocity seismic structure discovered in Earth’s outer core

    ByHarsha Borah

    Two Australian scientists discovered a ‘seismic abnormality’ in the Earth’s outer core — a “donut” of energy around the equator, where seismic waves move about 2% slower than in other core regions. Their study provides new clues about the dynamics of our planet’s magnetic field.

  • NASA’s Earth scientists explore South Atlantic Anomaly

    ByTeo Blašković

    Earth’s magnetic field acts like a protective shield around the planet, repelling and trapping charged particles from the Sun. But over South America and the southern Atlantic Ocean, an unusually weak spot in the field – called the South Atlantic…

  • Astronomers map Milky Way’s magnetic field

    ByJulie Celestial

    Astronomers from the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and Curtin University, in collaboration with colleagues from Europe, Canada, and South Africa published the most accurate catalog of measurements towards mapping the Milky…
