This view of the sun's magnetic field was generated by NASA's Solar Dynamics Observatory. ... The model developed by the team could help scientists better understand the 11-year solar cycle and ...
The instrument incorporates physics-based models in order to further scientific understanding of the relationship between solar EUV variations and magnetic variation changes in the Sun. [14] The Sun's output of energetic extreme ultraviolet photons is primarily what heats the Earth's upper atmosphere and creates the ionosphere.
NASA's Solar Dynamics Observatory scientists used computer models to generate a four-day, time-lapse view of the sun's changing magnetic field. The field lines are more concentrated in regions ...
NASA defines [2] heliophysics as "(1) the comprehensive new term for the science of the Sun - Solar System Connection, (2) the exploration, discovery, and understanding of Earth's space environment, and (3) the system science that unites all of the linked phenomena in the region of the cosmos influenced by a star like our Sun."
NASA's Parker Solar Probe is about to make its closest approach to the sun. The spacecraft will fly within 3.8 million miles of the solar surface. The spacecraft is collecting essential data that ...
The solar magnetic field extends well beyond the Sun itself. The electrically conducting solar wind plasma carries the Sun's magnetic field into space, forming what is called the interplanetary magnetic field. [86] In an approximation known as ideal magnetohydrodynamics, plasma particles only move along magnetic field lines. As a result, the ...
Scientists have revealed shock findings in the search to understand the Sun’s magnetic field. The effect – a mystery that has troubled scientists for centuries – begins relatively close to ...
The solar dynamo is a physical process that generates the Sun's magnetic field.It is explained with a variant of the dynamo theory.A naturally occurring electric generator in the Sun's interior produces electric currents and a magnetic field, following the laws of Ampère, Faraday and Ohm, as well as the laws of fluid dynamics, which together form the laws of magnetohydrodynamics.
