Many cultures built amazing solar monuments to celebrate the Sun...

In 1543, Copernicus' idea that the Sun was the center of the solar system changed everything.

Over the centuries a series of classic experiments in optics and chemistry--some of which you can find online at this site and try for yourselves--established the nature of the stars and our Sun.

Today new ideas and techniques make solar science one of the most exciting areas of astronomy.

We've figured out how to detect the Sun's magnetic fields, and use Sun sounds to peer deep down in it.

For many young researchers, the Sun isn't just history--it's the future!
