Researchers track slowly splitting ‘dent’ in Earth’s magnetic field

A small but evolving dent in Earth's magnetic field can cause big headaches for satellites. Earth's magnetic field acts like a protective shield around the planet, repelling and trapping charged particles from the Sun. But over South America and the... Continue Reading →

Jupiter’s Magnetic Field from Juno

How similar is Jupiter's magnetic field to Earth's? NASA's robotic Juno spacecraft has found that Jupiter's magnetic field is surprisingly complex, so that the Jovian world does not have single magnetic poles like our Earth. A snapshot of Jupiter's magnetic field at one moment in time, as animated... Continue Reading →

VLA Reveals Distant Galaxy’s Magnetic Field

With the help of a gigantic cosmic lens, astronomers have measured the magnetic field of a galaxy nearly five billion light-years away. The achievement is giving them important new clues about a problem at the frontiers of cosmology — the... Continue Reading →
