For thousands of years, people have watched the vibrant auroras dance across the night sky. But these magnificent displays are more than just a pretty sight. They are a warning sign of a hidden danger: geomagnetically induced currents. Auroras are caused by particles from the sun hitting the Earth’s magnetic field. These forces can compress … Read more
Credit: Harrison Haines from Pexels Auroras have inspired myths and omens for millennia, but only now, with modern technology that relies on electricity, do we appreciate their true power. The same forces that cause auroras also generate currents that can damage infrastructure that carries electricity, such as pipelines. Now scientists are writing in Frontiers in … Read more
The remarkable ability of migratory animals to navigate and remember routes may be attributed to their sensitivity to not only the Earth’s magnetic field, but possibly also to interactions with the magnetic bacteria that live in the field. The relationship between these magnetic bacteria and the animals they live in is not yet fully understood, … Read more
Recent studies have highlighted the catastrophic effects of extreme solar eruptions, especially when combined with a weakened magnetic field. These phenomena, which occur about once every thousand years, can significantly disrupt the Earth’s ozone layer, with serious consequences for all life on our planet. The protective role of the Earth’s magnetic field The Earth’s magnetic … Read more
The remarkable aurora borealis in early May this year showed just how powerful solar flares can be in the form of radiation. But every now and then the sun does something even more devastating. These proton explosions, known as “solar particle events,” come directly from the sun’s surface and can shoot out into space like … Read more

The sun is on the eve of an important event: a reversal of the magnetic field. This phenomenon occurs approximately every eleven years and marks an important stage in the development of the economy solar cycle. The shift in polarity indicates the halfway point maximum solar energythe height of solar activity and the beginning of … Read more
In the depths of our solar system – a realm where chemistry and speculation collide – scientists have reported the possible existence of a molecule known as aquodiium, an elusive cousin of the ammonium ion. If true, it could explain the oddities in the magnetic fields of Neptune and Uranus. This is a major problem … Read more
In an extraordinary scientific breakthrough, astronomers have discovered magnetic stars outside the Milky Way for the first time. These stars, located in the Magellanic Clouds, have provided new insights into stellar magnetism and the magnetic properties of stars in different galactic environments. This groundbreaking discovery, achieved using advanced telescopic and observational technologies, opens new frontiers … Read more
