Every so often the Moon passes directly between the Sun and the Earth, casting a shadow on the Earth and briefly blocking much of the Sun’s light from reaching the Earth. This, we call a solar eclipse.
Humans have long been fascinated by solar eclipses. Reports of occurrences come from ancient civilizations. Succeeding generations of astronomers would add their own records. By the 19th century though, astronomers were beginning to observe and measure the dimmer outer corona of the sun. Astronomers, eager to observe more solar eclipses, began to travel farther from their homes, traveling on expeditions to remote locations.
In recent years eclipse viewing has grown to encompass the scientific community in many more countries who contribute their reports to the collective body of scientific knowledge and observations have become ever more sophisticated.
