Since we began sending satellites to space, our knowledge of the sun has increased exponentially. We saw the sun at new wavelengths, observing our local star in ultraviolet and X-rays for the first time. These observations revealed many new unexplained phenomena on the sun. Many of these early solar observations have been long since explained, but there are still ongoing mysteries about the sun that scientists are working to understand.
Here, we outline three of the main outstanding puzzles of our local star, although there are certainly others. Most current and future projects to observe the sun, either from the ground or in space, include one or more of these mysteries as a primary science goal.
