What is a Total Solar Eclipse?
A solar eclipse (as seen from the planet Earth) is a type of eclipse that occurs when the Moon passes between the Sun and Earth, and when the Moon fully or partially blocks (“occults“) the Sun. This can happen only at new moon when the Sun and the Moon are in conjunction as seen from Earth in an alignment referred to as syzygy. In a total eclipse, the disk of the Sun is fully obscured by the Moon. In partial and annular eclipses, only part of the Sun is obscured.
If the Moon were in a perfectly circular orbit, a little closer to the Earth, and in the same orbital plane, there would be total solar eclipses every month. However, since the Moon’s orbit is tilted at more than 5 degrees to the Earth’s orbit around the Sun, its shadow usually misses Earth. The Moon’s orbit must cross Earth’s ecliptic plane in order for an eclipse (both solar as well as lunar) to occur. In addition, the Moon’s actual orbit is elliptical, often taking it far enough away from Earth that its apparent sizeis not large enough to block the Sun entirely. The orbital planes cross each other at a line of nodes resulting in at least two, and up to five, solar eclipses occurring each year; no more than two of which can be total eclipses. However, total solar eclipses are rare at any particular location because totality exists only along a narrow path on the Earth’s surface traced by the Moon’s shadow or umbra.
An eclipse is a natural phenomenon. However, in some ancient and modern cultures, solar eclipses were attributed to supernatural causes or regarded as bad omens. A total solar eclipse can be frightening to people who are unaware of its astronomical explanation, as the Sun seems to disappear during the day and the sky darkens in a matter of minutes.
Since looking directly at the Sun can lead to permanent eye damage or blindness, special eye protection or indirect viewing techniques are used when viewing a solar eclipse. It is technically safe to view only the total phase of a total solar eclipse with the unaided eye and without protection; however, this is a dangerous practice, as most people are not trained to recognize the phases of an eclipse, which can span over two hours while the total phase can only last a maximum of 7.5 minutes for any one location. People referred to as eclipse chasers or umbraphiles will travel to remote locations to observe or witness predicted central solar eclipses.
Suggested Christian Response taken from the last part of this blog.
As Christians, our perspective of the total solar eclipse can, and should, be cause for great celebration. Pay no attention to doomsday messages and apocalyptic threats about the end of time. These are meaningless and without truth. Jesus warned us that false prophets will try to deceive many (Matthew 25:24). In Mark 13:32, He assured us, “But of that day and hour no one knows, not even the angels in heaven, nor the Son, but only the Father.”
Take advantage of the opportunity for viewing the total solar eclipse. Celebrate with these verses as you do so:
- The Rising of the Sun
“But to you who fear My name, The Sun of Righteousness shall rise with healing in His wings” (Malachi 4:2a). This is a beautiful picture fulfilled by Jesus Christ who heals by the power of the message of the Cross.[x]
- The Remission of Sin
Remission means forgiveness of sin.[xi] John the Baptizer said something significant about this, and light, in his mission to “go before the face of the Lord to prepare His ways, (to) give knowledge of salvation to His people by the remission of their sins, through the tender mercy of our God, with which the Dayspring from on high has visited us; to give light to those who sit in darkness and the shadow of death, to guide our feet into the way of peace.” (Luke 1:76b-79)
- The Radiance of the Son
As a child of God, a believer in His Son Jesus Christ, you are filled with His Holy Spirit. You have the Light of Life (John 8:12). Heaven is your home. The Bible says in Revelation 22:5, “There shall be no night there: They need no lamp nor light of the sun, for the Lord God gives them light. And they shall reign forever and ever.”
On a side note, August is known as the month of Answered prayer.
