NASA’s Earth scientists explore South Atlantic Anomaly

NASA’s Earth scientists explore South Atlantic Anomaly

Earth’s magnetic field acts like a protective shield around the planet, repelling and trapping charged particles from the Sun. But over South America and the southern Atlantic Ocean, an unusually weak spot in the field – called the South Atlantic…

Study reveals South Atlantic magnetic anomaly is a recurring feature

Study reveals South Atlantic magnetic anomaly is a recurring feature

In a new study, scientists from the University of Liverpool in England traced back the strange behavior of the magnetic field in the South Atlantic region and found that similar anomalies existed as far back as 8 to 11 million years ago. The South Atlantic Anomaly…

World Magnetic Model (WMM) 2020 released

World Magnetic Model (WMM) 2020 released

A new World Magnetic Model (WMM) was officially released on December 10, 2019. WMM is a representation of the planet’s magnetic field that gives compasses dependable accuracy and one of the key tools developed to model the change in Earth's magnetic field….

Energy from Space – The Shift Has Begun

Energy from Space – The Shift Has Begun

Earth and Sun's fields are weakening and we're exiting the magnetic dust cloud. At the same time, our three shields against energy from space are disappearing, we are showing increased vulnerability to space weather from our sun, and cosmic rays are already…

Earth’s magnetic flip and what it means for human civilization

Earth’s magnetic flip and what it means for human civilization

Earth's magnetic field has flipped many times throughout history and is now on its way toward another reversal. While the topic was highly controversial in the 20th century, numerous studies over the past decades have proven this as a fact, that it's…

Study finds Earth’s magnetic field ‘simpler than we thought’

Study finds Earth’s magnetic field ‘simpler than we thought’

Scientists have identified patterns in the Earth’s magnetic field that evolve on the order of 1 000 years, providing new insight into how the field works and adding a measure of predictability to changes in the field not previously known. The discovery also…

Highest resolution map of Earth’s lithospheric magnetic field

Highest resolution map of Earth’s lithospheric magnetic field

After three years of collecting data, Swarm mission scientists have produced the highest resolution map of Earth’s lithospheric magnetic field from space to date. The dataset combines measurements from ESA’s Swarm satellites with historical data from the…
