Compasses were the trusted companions of sailors, explorers, and travelers for centuries, offering a simple way to find north ...

UC Santa Cruz applied mathematicians produced the first self-consistent models of the Sun’s tachocline incorporating the ...

The sun has become increasingly active since 2008, a new NASA study shows. Solar activity is known to fluctuate in cycles of ...

The Earth’s magnetic field briefly collapsed, leaving life on Earth exposed to increased solar and cosmic radiation. This ...

Scientists have developed a way to produce models of where the magnetic field lines are several times each day. Here we have created a time-lapse version of these models over four days (2-3 each day) ...

The sun has woken up grumpy this week, developing unusually unstable magnetic fields at some sunspots that may result in rare and violent X-class solar flares being fired at the Earth. X-class flares ...

The technology to predict when an earthquake will strike does not yet exist. Researchers have tried for decades to determine whether there is a reliable precursor that can act as an early warning ...

Researchers recently mapped out the magnetic field of the gargantuan galaxy cluster "El Gordo." The resulting map of swirling magnetic field lines is the largest of its kind. When you purchase through ...

Nuclear fusion promises a green and infinitely renewable supply of energy—if we can harness it. Fusion happens all the time ...

The traditional method for visualizing magnetic fields, which your science teacher probably demonstrated at some point, is to sprinkle some iron filings onto a piece of paper and hold it over a magnet ...
