Magnetic fields are the essential, but often "secret" ingredients of the interstellar medium and the process of making stars. The secrecy shrouding interstellar magnetic fields can be attributed to the lack of experimental probes.

Learn how forces deep underground generate a protective bubble between us and space.

Numerical simulations have shown that the strength of planetary magnetic fields depends on the convective energy flux emerging from planetary interiors. Here we model the interior structure of gas giant planets using \texttt{MESA}, to determine the convective energy flux that can drive the generation of magnetic field. This flux is then incorporated in the Christensen et al. dynamo formalism to estimate the maximum…

A NASA-funded researcher at the University of Iowa has figured out how to find X-points, places where the magnetic field of Earth connects to the magnetic field of the Sun.

How turbulent convection currents in Earth's outer core make its magnetic fieldThis video is a prequel to one that will appear here: http://ve42.co/SpinHuge ...

An international team of astronomers has discovered a magnetic field on exoplanet HAT-P-11b, a Neptune-sized world 123 light-years away.

On the dream list of many condensed matter physicists is observing fractionalization, the phenomena of a collective state of electrons carrying a charge that is a fraction of the electron charge, without a magnetic field.

Birds become just as restless for fall migration as they do for the spring event, but there is a twist that comes with studies that began over half a century

Earth's shifting magnetic field affects airports and airline operations, including runway names. NCEI's World Magnetic Model is a guide.

When we look out into space, all of the astrophysical objects that we see are embedded in magnetic fields. This is true not only in the neighborhood of stars and planets, but also in the deep space between galaxies and galactic clusters. These fields are weak—typically much weaker than those of a refrigerator magnet—but they are dynamically significant in the sense that they have profound effects on the dynamics of…

With a new study on the dynamics of plasma turbulence, MIT researchers are one step closer to solving the mysterious origins of cosmological magnetic fields. The work was led by graduate student Muni Zhou, her advisor Nuno Loureiro, and colleagues.

In 1859, the Carrington Event was the most intense global solar storm ever recorded. The effects were felt all over the Earth.

This week, marvel at the sun's complexity, discover a new side to Stonehenge, meet a clever corvid, explore a newly observed region of a black hole, and more...

Using the Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have detected the magnetic field of a galaxy so far away that its light has taken more than 11 billion years to reach us: we see it as it was when the Universe was just 2.5 billion years old. The result provides astronomers with vital clues about how the magnetic fields of galaxies like our own Milky Way came to be.

Using data from the Voyager 2 mission, researchers have modeled Uranus's off-kilter magnetosphere

The "big flip" may be on its way.

Astronomers have detected linearly polarized thermal emission from dust grains in 9io9, a strongly lensed, intrinsically luminous galaxy that is forming stars at a rate more than 1,000 times that of the Milky Way at redshift 2.6, within just 2.5 billion years of the Big Bang.

We are all very familiar with the concept of the Earth's magnetic field. It turns out that most objects in space have magnetic fields but it's quite tricky to measure them. Astronomers have developed an ingenious way to measure the magnetic field of the Milky Way using polarized light from interstellar dust grains that align themselves to the magnetic field lines. A new survey has begun this mapping process and has…

A new archaeological technique has been able to verify Old Testament accounts of military campaigns against the ancient Kingdoms of Israel and Judah.

Scientists in China have set a new world record for the strongest steady magnetic field ever generated on Earth. The hybrid magnet managed to produce a field measuring 45.22 Tesla (T), which is over a million times stronger than the planet's own.
