The Moon is Still Alive . . .

The moon is very much alive, geologically speaking. Ever since telescopes have been available, observers have been reporting many color changes, bright and colored spots and streaks, clouds, hazes, veils, and other phenomena on the moon. Since these phenomena are short lived, they are called Transient Lunar Phenomena (TLP). These speak of geologic activity.

Over 300 transient lunar phenomena have occurred in the Aristarchus region of the moon, indicating that the moon is young, just as the Bible says.

From 1900 to 1960, many of these observations were dismissed and ignored because the prevailing belief was that the moon is 4.5 billion years old and has been geologically dead for the last 3 billion years. (As the argument went, since the moon is about one-fourth of the size of the earth, heavy masses would fall to the center, the moon would cool much faster than the earth, and no magma would be left.) But the number of TLP observations became so overwhelming that mainline publications began to discuss them. In 1968, NASA published the Chronological Catalog of Reported Lunar Events.

As early as March 1787, William Herschel, the discoverer of Uranus and an ardent lunar observer, reported, “I perceive three volcanoes in different places of the dark side of the moon. Two of them are either extinct, or otherwise in a state of going to break out. . . . The third shows an actual erupt ion of fire, or luminous matter.” The next night he continued, “The volcano burns with greater violence than last night. I believe the diameter . . . to be about three miles.” More than 300 TLP’s have been seen in the Aristarchus region alone. This and hundreds of similar observations point to the youthfulness of the moon, as the Bible tells us.
