Getting Down to Earth with Space Hazards

Magnetic storms can interfere with the operation of electric power grids and damage grid infrastructure. They can also disrupt directional drilling for oil and...

Filling in gaps in the history of earth’s magnetic field

The Marcellus Shale is famous as a formation being explored for natural gas resources. That exploration has also offered some insight into an age-old...

Developing New Rock Magnetic Tools to Drive Geoscience Research

Just over 50 years ago, scientists first theorized that the magnetization of the ocean floor recorded the reversals of Earth’s geomagnetic field, as well...

Earth not due for a geomagnetic flip in the near future,...

The intensity of Earth's geomagnetic field has been dropping for the past 200 years, at a rate that some scientists suspect may cause the...

Earth’s magnetic shield is much older than previously thought

Since 2010, the best estimate of the age of Earth's magnetic field has been 3.45 billion years. But now a researcher responsible for that...

First measurements taken of South Africa’s Iron Age magnetic field history

A team of researchers has for the first time recovered a magnetic field record from ancient minerals for Iron Age southern Africa (between 1000...

An improved age for Earth’s latest magnetic field reversal using radiometric...

Earth's magnetic field periodically reverses such that the north magnetic pole becomes the south magnetic pole. The latest reversal is called by geologists the...

First sensor of Earth’s magnetic field in an animal

A team of scientists and engineers at The University of Texas at Austin has identified the first sensor of Earth's magnetic field in an...

Astronomers make real-time, 3D movies of plasma tubes drifting overhead

By creatively using a radio telescope to see in 3D, astronomers have detected the existence of tubular plasma structures in the inner layers of...

Missing link in metal physics explains Earth’s magnetic field

Earth's magnetic field is crucial for our existence, as it shields the life on our planet's surface from deadly cosmic rays. It is generated...

Death of a dynamo: A hard drive from space

Hidden magnetic messages contained within ancient meteorites are providing a unique window into the processes that shaped our solar system, and may give a...

Levitation recreates nature’s dumbbells

Using magnetic levitation to imitate weightlessness, researchers led by physicists at The University of Nottingham have manufactured solid wax models of splash form tektites....

Electromagnetic waves linked to particle fallout in Earth’s atmosphere, new study...

In a new study that sheds light on space weather's impact on Earth, Dartmouth researchers and their colleagues show for the first time that...

Understanding ancient geomagnetic reversal

Imagine one day you woke up, and the North Pole was suddenly the South Pole. This geomagnetic reversal would cause your hiking compass to seem...

First harvest of research based on the final GOCE gravity model

Just four months after the final data package from the GOCE satellite mission was delivered, researchers are laying out a rich harvest of scientific...

Turbulence in molten core helps amplify Earth’s magnetic field

Researchers at the Institut des Sciences de la Terre (CNRS/Université Joseph Fourier Grenoble 1/IRD/Université de Savoie/IFSTTAR) have shown that turbulence, random motion that takes...

Earth’s magnetic field could flip within a human lifetime

Imagine the world waking up one morning to discover that all compasses pointed south instead of north. It's not as bizarre as it sounds. Earth's...

Nuclear magnetic resonance experiments using Earth’s magnetic field

Earth's magnetic field, a familiar directional indicator over long distances, is routinely probed in applications ranging from geology to archaeology. Now it has provided...

Could Pulses in Earth’s Magnetic Field Forecast Earthquakes?

In the days leading up to some recent moderate-sized earthquakes, instruments nearby have picked up brief low-frequency pulses in Earth’s magnetic field. A few...

Swarm reveals Earth’s changing magnetism

The first set of high-resolution results from ESA's three-satellite Swarm constellation reveals the most recent changes in the magnetic field that protects our planet. Launched...
