Scientists across world are puzzled as to why there are flashes appearing on surface of moon. This unusual phenomenon has been happening several times week. Sometimes the flashes of light are very short, while at other times light lasts longer. Scientists have also observed that on occasion, there are places on moon's surface that darken temporarily. Experts on moon have been speculating on what is behind flashes. One scientist said the impact of meteorite can cause moon's surface to glow briefly. Another scientist wondered whether the flashes occurred when electrically charged particles of solar wind reacted with moon dust.

lunar telescope has been set up in Spain to observe what is happening on the moon. The head of team behind the telescope is Hakan Kayal, professor of space technology. He said: "Seismic activities were observed on moon. When surface moves, gases that reflect sunlight could escape from interior of the moon. This would explain luminous phenomena, some of which last for hours." He added: "The so-called transient lunar phenomena have been known since 1950s, but they have not been sufficiently observed." Professor Kayal said: "Anyone who wants to build lunar base at some point must of course be familiar with local conditions."
