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 ...

Scientists in the United States have created a small device that produces a tiny electrical signal from Earth’s natural rotation. Although the voltage is extremely small, the experiment shows that ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Using 11 years of magnetic field measurements from the ...

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 ...

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

For nearly 20 years, physicists and engineers have chased the idea of invisibility. Early efforts focused on hiding objects from light using so-called metamaterials with extreme and often unrealistic ...

Dan Joling of Anchorage was set to photograph the full moon rising over the Port of Anchorage on Jan. 6. His research told him the moon would pop over the horizon at a certain number of degrees from ...

Artifacts from the Iron Age have revealed an intense historical magnetic anomaly in the Middle East. Could using a similar approach elsewhere help us unravel the mysteries of Earth's magnetic field?

When Santa is done delivering presents on Christmas Eve, he must get back home to the North Pole, even if it's snowing so ...
