Magnetic field

Pinning down the timing of lunar dynamo’s demise

Findings suggest the moon’s magnetic field was produced by the fallout of a crystallizing iron core.

Scientists found a killer electron hot spot in Earth’s Van Allen radiation belts

JAXA and NASA satellite observations show where killer electrons are generated in the Van Allen radiation belts surrounding Earth.

How spiral-shaped galaxies get their iconic shape?

Our Milky Way galaxy has an elegant spiral shape with long arms filled with stars, but exactly how it took this form has long puzzled scientists.

Mapping our galaxy’s magnetic field

Expanding our knowledge of the Milky Way's 3-D structure.

Scientists reproduced the dynamics behind high-energy astrophysical shocks

Now experiments led by researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) in the Princeton Center for Heliophysics have for the first time reproduced the process behind the source of astrophysical shocks.

IBS researchers performed world’s smallest MRI on single atoms

Researchers at the Center for Quantum Nanoscience (QNS) within the Institute for Basic Science (IBS) at Ewha Womans University in collaboration with colleagues from...

New small, compact coil generated world’s strongest continuous magnetic field

Researchers at the Florida State University-based National High Magnetic Field Laboratory have created a toilet paper roll-sized magnet which is less than a centimeter...

Jets and winds from galaxy cores appear to share a common cause

Fundamental considerations of the energy supply in large-scale extragalactic radio sources("radio galaxies") led astronomers to predict that these sources should contain jets or beams...

Some humans can sense Earth’s magnetic field, suggests study

Magnetoreception, the perception of the geomagnetic field, is a sensory modality well-established across all major groups of vertebrates and some invertebrates, but its presence...

What magnetic fields can tell us about life on other planets?

Earth has a magnetic field – it’s what makes compasses align north-south and lets us navigate the oceans. It also protects the atmosphere, and...

Magnetic fields may be the key to black hole activity

Black holes are objects so dense, and with so much mass, that even light cannot escape their gravity. However, astronomers can study the effects...

Newly developed instrument provides new look at supermassive black hole’s magnetic field
