  • Activity deep in Earth affects the global magnetic field

    Updated: 2023-03-16 05:44:42
    Compass readings that do not show the direction of true north and interference with the operations of satellites are a few of the problems caused by peculiarities of the Earth's magnetic field. The magnetic field radiates around the world and far into space, but it is set by processes that happen deep within the Earth's core, where temperatures exceed 5,000-degrees C. New research from geophysicists suggests that the way this super-hot core is cooled is key to understanding the causes of the peculiarities -- or anomalies, as scientists call them -- of the Earth's magnetic field.

  • Where did Earth's water come from? Not melted meteorites, according to scientists

    A new study brings scientists one step closer to answering the question of where Earth's water came from.

  • Mineral particles and their role in oxygenating the Earth's atmosphere

    Updated: 2023-03-06 19:34:27
    Mineral particles played a key role in raising oxygen levels in the Earth's atmosphere billions of years ago, with major implications for the way intelligent life later evolved, according to new research.
