Rotación Diferencial del Sol Eyecciones de masa coronal
Although the Sun is an ordinary star in our Galaxy, it is the dominant object in our Solar System, and essential for life on Earth. A variation of only a few percent of its energy output would cause disastrous climate changes on Earth. Therefore, it is very important to observe and study the Sun, and to understand as much as possible how it works. Moreover, we can use the Sun learn more about our Solar System, and to test some physical theories, such as Einstein's Theory of Relativity. |
