"Revealing how the Sun behaves beneath its surface during these quiet periods is significant because this behavior has a strong bearing on how the activity levels build up in the cycles that follow," ...

The Sun in ultraviolet, as seen by the NASA Solar Dynamics Observatory, during two periods: one the recent solar minimum in around 2019, and the solar maximum that preceded it, when the Sun was much ...

New study reveals that even small differences in solar magnetic activity produce detectable changes inside the Sun.

The unexpected surge of solar activity during the ongoing solar maximum may be tied to a lesser-known, 100-year-long cycle that is just beginning to ramp up again, a new study suggests. If that's true ...

Activity on the sun is not constant; it varies along a cycle of about 11 years. The peak of this solar cycle — called solar maximum — is when sunspots, solar flares and coronal mass ejections (CMEs) ...

The Sun experienced its first spotless days in four years, from February 22-24, 2026, indicating a shift towards a calmer ...

Astronomers observed the sun without a single sunspot for the first time in over three years, hinting at a slowdown in Solar ...
