For many years now, the activity of the Sun’s 11-year solar cycle has been gauged through visible indications like sunspots, ...

Internal changes due to the sun's "active biorhythm" have become increasingly "skin-deep" over the past four solar activity cycles, according to a new study.

When you look up at the sky on a sunny day, the Sun might seem like a bright spot, unchanging in the sky. But the Sun is a complex, dynamic celestial body, wrapped in electrical currents and magnetic ...

For more than two decades, a global network of telescopes has been eavesdropping on the sun by tracking millions of tiny ...

A solar flare imaged by NASA's Solar Dynamics Observatory in 2024. (NASA SDO) Scientists have just realized that surface ...

Scientists have uncovered previously hidden changes in the Sun's solar activity over the last 40 years, which could affect ...

The findings indicate a “structural reorganization of how the Sun’s magnetic activity is stored beneath the surface,” Basu ...

The Sun transports energy from its interior through convection, a process similar to the movement of hot water in a boiling ...

Every eleven years, the sun's magnetic field flips. Sunspots—dark, cooler regions on the sun's surface that mark intense magnetic activity and often trigger solar eruptions—appear at mid-latitudes and ...

Solar cycle space weather models may be miscalibrated: a new helioseismology study found the Sun’s magnetic activity has retreated toward its surface since 1987 in ways sunspot counts never detected.

Scientists studying 50 years of solar data warn Earth may be entering a heightened risk period for rare “superflares” capable of disrupting technology worldwide.
