The moon is still so mysterious. These are photos of:
What are TLPs?
1) A map of reported TLPs (created by NASA in 1964)
2) A transient lunar phenomenon
3) Photo of the Aristarchus crater, which is the brightest spot on the moon and has a mysterious glow. This crater is the most common area for TLP sightings.
"A transient lunar phenomenon (TLP), or lunar transient phenomenon (LTP), is a short-lived light, color, or change in appearance on the surface of the Moon."
Most people have never heard of TLPs because scientists typically steer clear of talking about these strange colorations and unidentified flying lights. It is only speculation as to what causes these phenomenon and given the variance of reports, they could be a variety of different things.
NASA’s Project Moon-Blink
The Aristarchus Crater
In 1965 NASA conducted Project Moon-Blink to specifically study strange phenomenon on the surface of the moon. The study concluded that,
“Red colorations do appear on the lunar surface.
These colorations may persist for several hours. The Trident sighting, on November 15, 1965, lasted at least four hours (sunrise prevented further viewing).”
"The region of the Aristarchus plateau has been the site of many reported transient lunar phenomena, with a total of 122 such reports by 2007; the highest recorded for any lunar feature. Such events include temporary obscurations and colorations of the surface, and catalogues of these show that more than one-third of the most reliable spottings come from this locale. In 1971 when Apollo 15 passed 110 kilometers above the Aristarchus plateau, a significant rise in alpha particles was detected. These particles are believed to be caused by the decay of radon-222, a radioactive gas with a half-life of only 3.8 days." -via http://en.m.wikipedia.org/wiki/Aristarchus_(crater)
