Mapping the Earth’s magnetic field – to find oil, track storms or probe the planet’s interior – typically requires expensive satellites. University of California, Berkeley, physicists have now come up ...

New research is turning a long‑standing hunch about sea turtles into a detailed map of how these animals read the planet itself. Scientists are now showing that turtles do not just sense Earth’s ...

Ancient bricks inscribed with the names of Mesopotamian kings have yielded important insights into a mysterious anomaly in Earth's magnetic field 3,000 years ago, according to a new study. Ancient ...

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 ...

Researchers from The Immanuel Kant Baltic Federal University developed a new unexpensive method of magnetic field mapping. Using 3D-printer and common laboratory equipment their team created automatic ...

Loggerhead turtles are able to sense Earth's magnetic field in two ways, but it wasn't clear which sense the animals use to detect the magnetic field when navigating using the magnetic map they are ...

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

Although the Earth’s magnetic field is reliable enough for navigation and is also essential for blocking harmful solar emissions and for improving radio communications, it’s not a uniform strength ...

Summary: The U.S. National Science Foundation (NSF) Daniel K. Inouye Solar Telescope, the world’s most powerful solar telescope, operated by the NSF National Solar Observatory (NSO), achieved a major ...
