On August 21, 120 RTB staff members and guests will experience a perfect solar eclipse during our conference at the Washington Family Ranch in eastern Oregon. A perfect solar eclipse occurs when the disk of the Moon exactly blocks out the disk of the Sun.
For the past 4.5 billion years, the Moon has been moving away from the Earth. Currently, it is speeding away at a rate of 3.82 centimeters per year. The Moon’s recession from Earth means that the window for observing perfect solar eclipses is only about 300 million years wide. We humans “happen” to be living on Earth at the midpoint of those 300 million years.
