Sun’s Core Rotates Nearly 4 Times Faster than Its Surface, SOHO Data Reveal
Aug 2, 2017 by News Staff / Source
Using data from the NASA/ESA Solar and Heliospheric Observatory (SOHO), solar physicists have found evidence of a type of seismic wave (gravity waves, or g-waves) in the Sun. These low-frequency waves reveal that the deepest part of the solar body, its hydrogen-burning core, rotates about 4 times faster than the solar surface.
