Every star, including the Sun, hosts a magnetic field. One of the most notable products of stellar magnetic activity is X-ray emission (Fig. 1), most of which comes from active regions — areas on a ...

Using one of the world's most powerful laser facilities, a team of scientists experimentally confirmed a long-held theory for cosmic magnetic field generation: the turbulent dynamo. By creating a hot ...

The Earth's global magnetic field is generated in its metallic core, located nearly 3,000 kilometers beneath the planet’s surface. The field has existed on Earth for at least 3.5 billion years and ...

The massive, churning core of conducting liquids in stars and some planets creates a dynamo that generates the planetary body's magnetic field. Researchers aim to better understand these dynamos ...

The universe is highly magnetic, with everything from stars to planets to galaxies producing their own magnetic fields. Astrophysicists have long puzzled over these surprisingly strong and long-lived ...

WASHINGTON, D.C., May 23, 2017 -- The massive, churning core of conducting liquids in stars and some planets creates a dynamo that generates the planetary body's magnetic field. Researchers aim to ...

A new simulation based on the von-Kármán-Sodium (VKS) dynamo experiment takes a closer look at how the liquid vortex created by the device generates a magnetic field. Researchers investigated the ...
