Scientists discovered Earth’s magnetic field is weakening over the Atlantic Ocean, but what does that mean for life on the ...

Earth's magnetic field dramatically flipped roughly 41,000 years ago. We can now experience this epic upheaval, thanks to a clever interpretation of information collected by the European Space ...

It used to be thought that there were more volatiles than expected in lunar soil because they escaped Earth before it had a stable magnetic field. Researchers who ran simulations of these atmospheric ...

A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a ...

Pigeons may sense Earth’s magnetic field using their inner ear, sending signals to brain areas that help with navigation and memory.

A giant sunspot may be about to erupt, sending out the most powerful form of solar flares growing for days. Sunspot AR3089, which is facing towards the Earth, has now developed a delta-class magnetic ...

Magnetic fields play an important—if sometimes underappreciated—part in planetary systems. Without a strong magnetic field, planets can end up as a barren wasteland like Mars, or they could indirectly ...

It's time to recalibrate the navigation systems on ships, airplanes, and (given the time of year) Santa's sleigh: the position of the magnetic North Pole is officially being changed, continuing its ...

An illustration of the sun's magnetic fields overlaid on an image of the sun captured by NASA's Solar Dynamics Observatory in 2016. NASA / SDO / AIA / LMSAL The sun’s magnetic field could form much ...

Voyager 2 data from Uranus and Neptune revealed their magnetic fields are non-dipolar and disordered, a stark contrast to the dipolar fields observed on Earth, Jupiter, and Saturn. Astronomer Burkhard ...
