Deep in the core of most galaxies, hidden by spinning clouds of gas and dust, black holes spin like cosmic engines. These ...

In recent years, NASA's Parker Solar Probe has given us a close-up look at the sun. Among the probe's revelations was the ...

Geophysicists have modeled how Earth’s magnetic field could form even when its core was fully liquid. By removing the effects ...

A new model uncovers how Earth’s liquid core has sustained its magnetic field since the planet’s beginnings, offering new insights into its future. Earth benefits from the presence of a magnetic field ...

We encounter magnetic field sensors everywhere today – but few of us know it. These sensors make sure washing machines run concentrically, that headlights automatically adjust to the correct angle if ...

Earth is surrounded by a magnetic field generated by electric currents from within the planet. Compasses take advantage of this field to identify north and serve as a navigational aid. But one social ...

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 ...

Using 11 years of magnetic field measurements from the European Space Agency's Swarm satellite constellation, scientists have ...

In 2009, NASA's Chandra X-ray Observatory released a captivating image: a pulsar and its surrounding nebula that is shaped like a hand. Since then, astronomers have used Chandra and other telescopes ...
