For observers on Earth, the sun appears as a bright, familiar disk—but what we see is only half the story. Like the moon, one ...

Scientists have created the world's thinnest magnet, just one atom thick, which could revolutionize computer memory in the ...

Researchers have found that magnetic fields buried deep inside stars can survive their entire lifetimes and later reappear on ...

The original version of this story appeared in Quanta Magazine. Our planet is doomed. In a few billion years, the sun will exhaust its hydrogen fuel and swell into a red giant—a star so big it will ...

In the beginning, there was no magnetism. Immediately after the Big Bang, the universe contained an awesomely hot cloud of electrically charged protons, electrons, helium and lithium nuclei. Each ...

Step into a world so tiny, it defies imagination -- the nanoscale. Picture a single strand of hair, now shrink it a million times. You've arrived. Here, atoms and molecules are the architects of ...

Widespread magnetism dating from our solar system’s earliest beginnings some 4.57 billion years ago likely played a major role in creating orbital order out of chaos. But until now, magnetism’s role ...

The original version of this story appeared in Quanta Magazine. Amid the roilings of the Milky Way, immense pockets of gas coalesce into clouds where stars are born. In this process, there is a hidden ...

Scientists are now proposing a novel approach to achieve greater memory density while producing less heat: by using an electric field instead of a current to turn magnetism on and off, thereby ...

I have a confession: I'm obsessed with magnets. We rely on magnets every day, but seldom give them a second thought. There are magnets in your credit card, your cellphone, your car, microwave oven and ...
