    • Using seismic waveform data, researchers believe they’ve discovered Earth’s even smaller inner core.
    • The new inner core is made up of about 400 miles of dense iron, the researchers say.
    • Seismic waves inside the planet represents the only way to really study the inner core.

    In a real center-of-a-Tootsie Pop situation,
    we may not ever know how inner Earth’s inner core really is. But it’s more than you think.

    In a new study published in Nature Communications, a pair of researchers
    from the Australian National University in Canberra
    say they’ve found an “innermost inner core” for Earth,
    a roughly 400-mile thick innermost ball comprised of mainly iron.

    This is smaller and separate from what has long been held as Earth’s inner core tradition.

    Earth’s inner core, believed to be a 762-mile mix of iron and nickel that makes up
    less than 1 percent of Earth’s volume, isn’t easy to study.

    Scientists have relied on waveforms reverberating from selected earthquakes
    along Earth’s diameter, using travel times of seismological events to model the inner core.

    In the new study, the pair believes that by stacking these reverberating waves
    from the world’s growing seismograph network, they’ve found the inner core
    has an outer shell that is different from the true inner core.

    The studied waves offer differing angles and speeds for the inner core’s outer shell
    versus the now-believed distinctive innermost inner core.
    The scientists also extrapolate that this finding offers a
    “fossilized record of a significant global event from the past.” They explain:
    “Although the geomagnetic field might have preceded the inner core's birth,
    detectable changes in the inner core’s structures with depth could signify shifts
    in the geomagnetic field's operation, which could have profoundly influenced
    the Earth's evolution and its eco-system.”​
    The study authors believe “proving the innermost part of the inner core is critical
    to further disentangling the time capsule and understanding Earth’s evolution in the distant past.”
