Researchers at Nagoya University in Japan have conducted the most detailed simulation of the interior of stars and disproved a theory scientists have believed for 45 years: that stars switch their ...

The sun's differential rotation pattern has puzzled scientists for decades: While the poles rotate with a period of approximately 34 days, mid-latitudes rotate faster and the equatorial region ...

Many objects in space rotate. Earth completes a spin in roughly 24 hours, while Venus takes a whopping 243 Earth days. The moon's rotational period is about 27 days. The sun, it turns out, also ...

The interior of the Sun does not rotate at the same rate at all latitudes. The physical origin of this differential rotation is not fully understood. It turns out, long-period solar oscillations ...

Strong magnetic fields keep the equator spinning faster than the poles and prevent a rotation flip, even as stars slow down with age Researchers at Nagoya University in Japan have conducted the most ...
