Mapping the Earth’s magnetic field – to find oil, track storms or probe the planet’s interior – typically requires expensive satellites. University of California, Berkeley, physicists have now come up ...

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes that ...

For observers on Earth, the sun appears as a bright, familiar disk—but what we see is only half the story. Like the moon, one ...

Long before life thrived in Earth’s oceans, the planet’s magnetic field became disorganized. Deep within the ancient rocks of Morocco, scientists have recovered one of the clearest records of that ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. Using magnetic traces preserved in iron oxide grains within ...

Alfredo has a PhD in Astrophysics and a Master's in Quantum Fields and Fundamental Forces from Imperial College London. Alfredo has a PhD in Astrophysics and a Master's in Quantum Fields and ...

For the first time, scientists have mapped the magnetic fields on the far side of the sun, a region invisible from Earth. Using helioseismology, they analyzed sound waves traveling through the solar ...

Ancient bricks may be key to understanding Earth’s variable magnetic fields. Scientists examined the iron oxide levels of 3,000-year-old bricks to understand the level of magnetism the bricks were ...
