New research indicates that the Sun’s magnetic field originates much closer to the surface than previously thought, a finding that could help predict periods of extreme solar storms like the one struck the earth earlier this month. It appears that the magnetic field originates 20,000 miles below the surface of the sun. Previous calculations placed … Read more

New research shows that the Sun’s magnetic field originates near the surface and not deep within the star. . This upends decades of prevailing scientific thinking, which placed the field more than 130,000 miles below the surface of the sun. It also brings us closer to understanding the nature of the Sun’s magnetic field, which … Read more
Scientists have found the possible origin of the sun‘s magnetic field, and it’s not where they thought it was. The discovery, made using complex computer simulations, suggests that the Sun’s magnetic field arises from instabilities in the plasma in the outer layers of the Sun’s surface, rather than deep within the star, as researchers previously … Read more
Magnetic fields in the Milky Way’s halo have a toroidal structure, extending in a radius range from 6,000 light-years to 50,000 light-years from the center of the Milky Way. The sun is about 30,000 light years away. Credit: NAOC Astrophysicists have discovered large magnetic toroids in the Milky Way‘s halo, which affects cosmic ray propagation … Read more
For the first time, scientists have magnetized a non-magnetic material at room temperature, creating a quantum property that they say could pave the way for ultra-fast computing. The ‘switchable’ magnetic field could one day be used to store and transmit information. This was something that was previously only possible at ultra-cold temperatures. The results pave … Read more
