Scientists have analyzed more than 40 years of astronomical data to uncover evidence that the sun's internal structure subtly changes from one solar cycle minimum to the next. Publishing their ...

Helioseismic data traces the solar dynamo to the tachocline about 200,000 km down.

The Sun’s magnetic field is invisible to our eyes, but it quietly shapes everything from the shimmering auroras over the poles to the reliability of GPS on a jet’s navigation screen. When that ...

The Sun's internal structure shows subtle changes even during the calmer phases.

The Sun's magnetic field impacts the movement of plasma on the sun's surface, but it does not actually impact the amount of heat the sun emits. Solar flares, for example, are huge explosions that ...

The Sun is subtly changes in ways we have not previously fully understood, according to new research. Astronomers looked at data on the Sun taken over the course of more than 40 years and found that ...
