Earth orbits the sun while the moon orbits Earth. Occasionally, all three of them become aligned with one another. When this happens, an eclipse occurs. There are two types of eclipses: solar and lunar. Both are rare events simply because, due to the movement of all three celestial bodies, the times when they line up with one another are infrequent.

     Solar eclipses are easily the more spectacular of the two. For a solar eclipse to occur, the moon's orbit must take it between Earth and the sun. While the sun is much larger than the moon, the relative nearness of the moon to Earth makes it appear to be the same size as the sun when viewed from the ground. Thus, when the sun, Earth, and moon are perfectly aligned, the moon appears to cover the entire sun. This is a solar eclipse. A solar eclipse may be either total or partial.      When a total eclipse happens, the sun is completely obscured by the moon. The sky darkens, and it appears to be night time. However, most solar eclipses are partial ones. When they take place, the sun is only partly covered by the moon.

     When a solar eclipse happens, it is observable from a fairly small area on the planet. Thus, when there is a solar eclipse in North America, it is highly unlikely that it will be visible in Africa or Australia. A solar eclipse only lasts for a few minutes since all three heavenly bodies are in continual motion. People must also take care when viewing a solar eclipse since looking directly at it can cause damage - including blindness - to their eyes.

     Lunar eclipses happen when Earth moves directly between the sun and the moon. When this occurs, the planet blocks sunlight from reflecting off the moon. Lunar eclipses take place at night. During one, the moon appears very orange and is practically red in color. There are two different types of lunar eclipses. Taken together, the result is that lunar eclipses happen more frequently than solar eclipses. In addition, lunar eclipses may last for hours and can be seen from a wider area on the planet. There is no harm in directly observing a lunar eclipse either, so looking at one will not damage a person's eyes.

 Scientists are now looking for cheaper way to use solar energy to heat air and water. Many buildings are using solar energy to heat their water now. Solar unit on the roofs of buildings collect the energy and use it to heat water. Although these units are still very expensive, more and more people are buying solar hot water heaters. Universities and colleges give solar energy courses where students learn to build their own solar collectors. They are also many books that explain the construction of solar collectors. In the future, there will be more and more solar collectors, especially in the sunny desert areas of the world.
