It is fortunate for many reasons. Thus, from specific spots on Earth at specific times, it is possible to be in the Moon's shadow with the Sun completely blocked.
Many people travel around the world to position themselves in the path of a total solar eclipse.
Not only tourists travel to eclipses, however. While a beautiful sight , they also offer scientists a unique opportunity for research. Solar Physicists use solar eclipses as a method of studying the Sun. Using solar eclipses throughout history , scientists have discovered that the Sun's corona is approximately three million degrees in temperature. Thus, somehow the heat from the Sun's core is transmitted to the Sun's corona without heating the Sun's surface.
