Every several years, magnetic field observatories record quick changes to the position or strength of the planet’s magnetic field, so-called geomagnetic jerks. The cause of these shifts has remained a mystery. Continue reading Blobs in Earth’s Core Could Be Causing ‘Geomagnetic Jerks’ in the Magnetic Field
The beating heart of our planet has remained a mystery for scientists searching for how Earth formed and what went into its creation. But a recent study was able to recreate the intense pressures approaching those found in the center of the Earth, giving researchers a glimpse into our planet’s early days, and even what the core may look like now.
