Cosmic rays streamed through Earth's atmosphere 41,000 years ago: New findings on the Laschamps excursion

Earth's magnetic field protects us from the dangerous radiation of space, but it is not as permanent as we might believe. Scientists at the European Geosciences Union General Assembly present new information about an 'excursion' ...

Migratory bats can detect the Earth's magnetic field, behavioral experiments show

Pipistrelle bats have a magnetic compass and calibrate it at sunset, according to a new study. An international team of researchers led by the University of Oldenburg has used behavioral experiments to show that two different ...

Earth's magnetic field protects life on Earth from radiation, but it can move, and the magnetic poles can even flip

The Earth's magnetic field plays a big role in protecting people from hazardous radiation and geomagnetic activity that could affect satellite communication and the operation of power grids. And it moves.

Earth's past and future habitability depends on our protection from space weather

A bewildering number of factors and variables led up to the planet we occupy today, where life finds a way to survive and even thrive in the most marginal conditions. The sun is the catalyst for it all, propelling life on ...

Study models geomagnetic field shielding over the last 100,000 years

New models of how the geomagnetic field that shields the Earth's atmosphere from cosmic rays has changed over tens of thousands of years can help us understand how the climate has changed over a similar timescale.

Study offers new, sharper proof of early plate tectonics, flipping of geomagnetic poles

New research analyzing pieces of the most ancient rocks on the planet adds some of the sharpest evidence yet that Earth's crust was pushing and pulling in a manner similar to modern plate tectonics at least 3.25 billion years ...

The Earth moves far under our feet: A new study shows that the inner core oscillates

USC scientists have found evidence that the Earth's inner core oscillates, contradicting previously accepted models that suggested it consistently rotates at a faster rate than the planet's surface.

Earth's magnetic poles not likely to flip

The emergence of a mysterious area in the South Atlantic where the geomagnetic field strength is decreasing rapidly, has led to speculation that Earth is heading towards a magnetic polarity reversal. However, a new study ...
