Blobs in Earth’s Core Could Be Causing ‘Geomagnetic Jerks’ in the Magnetic Field

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

Glowing Antineutrino Map Shows How Radioactive the Earth Is

It’s often said that we know less about Earth’s deep interior than we do about the surface of Mars (or maybe even Pluto). A new global map of subatomic particles called antineutrinos is helping to change that. It’s showing scientists just how radioactive our little Blue Marble is.
