The Sun's core makes a complete rotation in one week

(CNRS) Researchers have determined that the Sun's core makes a complete rotation once per week. Using the GOLF instrument, orbiting around the Sun on board the SOHO space observatory, to measure solar oscillations, they developed a novel approach that enabled them to unambiguously detect gravity oscillation modes within our star. This work, which will certainly stimulate a new era of research into the physics of the solar core, is published in the journal Astronomy & Astrophysics.
