  4. Dungey Cycle (Planetary science 🪐)

    The Dungey cycle, officially proposed by James Dungey in 1961, is a phenomenon that explains interactions between a planet's magnetosphere and solar wind. Dungey originally proposed a cyclic behavior of magnetic reconnection between Earth's magnetosphere and flux of solar wind. This reconnection explained previously observed dynamics withi...

    “On 13 December, the rare alignment of true north, magnetic north and grid north - known as the three norths - leaves England at Berwick-upon-Tweed, bringing a remarkable three-year chapter to a close.
    Magnetic north is monitored using geomagnetic data from the British Geological Survey, combined with Ordnance Survey’s National Grid to track how this alignment shifts over time..."

  11. Villagers in Bidar, Karnataka, India, were surprised by the sudden land of a stratospheric balloon amidst homes.

    The device aimed to study the earth's magnetic field, was launched on Friday, January 17th from TIFR's National Balloon Facility in Hyderabad.

  12. Paleointensity (Earth sciences 🌍)

    In geomagnetism, paleointensity is the study of changes in the strength of the geomagnetic field over Earth's history. Émile and Odette Thellier were the first to make laboratory measurements to determine the strength of the ancient field responsible for producing remanent magnetization in a rock or archeological artifacts.

  13. Substorm (Earth 🌍)

    A substorm, sometimes referred to as a magnetospheric substorm or an auroral substorm, is a brief disturbance in the Earth's magnetosphere that causes energy to be released from the "tail" of the magnetosphere and injected into the high latitude ionosphere. Visually, a substorm is seen as a sudden brightening and increased movement of auroral arcs. Substorms were first described in qu...
