Nature Nugget – Eclipses

The Moon has no light of its own, but reflects light from the Sun. Eclipses occur when the Moon moves into a position of direct alignment with the Sun and Earth. There are two basic types of eclipses: lunar and solar. A lunar eclipse can only occur when the Moon is full and the Sun and Moon are on opposite sides of the Earth. The Moon passing through some portion of the Earth’s shadow causes the eclipse. The Earth’s shadow is composed of two cone-shaped components, one inside the other. The outer or penumbral shadow is a zone where the Earth blocks part but not all of the Sun’s rays from reaching the Moon. The inner or umbral shadow is a region where the Earth blocks all direct sunlight from reaching the Moon. There are two main types of lunar eclipses. Partial lunar eclipses occur when a portion of the Moon passes through Earth’s umbral shadow. Total lunar eclipses occur when the entire moon passes through Earth’s umbral shadow. Both these types of lunar eclipses are easily seen with the naked eye.

Solar eclipses occur when the New Moon passes directly between the Earth and the Sun causing a shadow to fall on the Earth. Like the Earth’s shadow during a lunar eclipse, the Moon’s shadow during a solar eclipse also has umbral and penumbral zones. And like the lunar eclipses, there are partial and total solar eclipses, depending on what part of the Moon’s shadow a particular part of the Earth passes through. During a solar eclipse, the Moon’s umbra shadow on the Earth creates a “path of totality” up to 200 miles wide that traces across the surface of the Earth. Within this zone daytime turns into an eerie darkness. Outside this zone, in the Moon’s penumbral shadow, some portion of the Sun’s bright disk remains visible. Solar eclipses are rare and are usually a once-in-a-lifetime event.

As the Moon reflects the Sun’s light to the Earth which is covered in darkness, so we as Christians are to reflect light from the Son of God to this dark, sinful world. We are not to let Satan get in the way and eclipse the light we receive and reflect from the Son to the world. “Satan’s work is to lead men to ignore God, to so engross and absorb the mind that God will not be in their thoughts. The education they have received has been of a character to confuse the mind and eclipse the true light. Satan does not wish the people to have a knowledge of God; and if he can set in operation games and theatrical performances that will so confuse the senses of the young that human beings will perish in darkness while light shines all about them, he is well pleased.” The Adventist Home, 401. “Satan is ever on the alert to deceive and mislead. He is using every enchantment to allure men into the broad road of disobedience. He is working to confuse the senses with erroneous sentiments, and remove the landmarks by placing his false inscription on the signposts which God has established to point the right way. It is because these evil agencies are striving to eclipse every ray of light from the soul that heavenly beings are appointed to do their work of ministry, to guide, guard, and control those who shall be heirs of salvation. None need despair because of the inherited tendencies to evil, but when the Spirit of God convicts of sin, the wrongdoer must repent and confess and forsake the evil. Faithful sentinels are on guard to direct souls in right paths.” Our High Calling, 92.
