Earth's magnetic poles could start to flip. What happens then?
As Earth's magnetic shield fails, so do its satellites. First, our communications satellites in the highest orbits go down. Next, astronauts in low-Earth orbit can no longer phone home. And finally, cosmic rays start to bombard ...

Researchers develop a new technique to forecast geomagnetic storms
The Earth's magnetic field extends from pole to pole and is strongly affected by solar wind from the sun. This "wind" is a stream of charged particles constantly ejected from the sun's surface. Occasional sudden flashes of ...

Earth's magnetic field is not about to reverse, study finds
A study of the most recent near-reversals of the Earth's magnetic field by an international team of researchers, including the University of Liverpool, has found it is unlikely that such an event will take place anytime soon.

Space weather threatens high-tech life
Shortly after 4 a.m. on a crisp, cloudless September morning in 1859, the sky above what is currently Colorado erupted in bright red and green colors. Fooled by the brightness into thinking it was an early dawn, gold-rush ...

New 3-D measurements improve understanding of geomagnetic storm hazards
Measurements of the three-dimensional structure of the earth, as opposed to the one-dimensional models typically used, can help scientists more accurately determine which areas of the United States are most vulnerable to ...

Mysterious 'geomagnetic spike' 3,000 years ago challenges our understanding of the Earth's interior
The Earth's magnetic field, generated some 3,000km below our feet in the liquid iron core, threads through the whole planet and far into space – protecting life and satellites from harmful radiation from the sun. But this ...

Could solar storms that cause the northern lights cause whale strandings?
A series of sperm whale strandings saw 29 of the animals beached across the North Sea in early 2016. As these whales are not normally found in the North Sea, the strandings were a bit of a mystery. But a study is now proposing ...

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 ...
