Momentary flashes of light on the moon are often attributed to meteor strikes or electrical phenomena. There are also those who throw conspiracy theories by suggesting a UFO activity on the moon. These lunar eclairs tend to occur throughout the week and appear near the surface of the moon. And yet, the exact cause of these flashes remains a mystery to science.
Professor Hakan Kayal, from the University of Würzburg, Germany, is studying another theory that suggests that seismic activity on the moon could be the cause.
The astronomer said: "The so-called transient lunar phenomena have been known since the 1950s, but they have not been sufficiently observed in a systematic and long-term way."
According to the professor's theory, the seismic activity on the Moon releases gases from the surface of the Moon.
These gases then act as a reflective surface, shining with light for long periods.

Professor Kayal said: "Seismic activities have also been observed on the moon.
"When the surface moves, gases reflecting sunlight can escape from inside the moon.
"That would explain the luminous phenomena, some of which last for hours."
Seismicity on the Moon is not a new phenomenon. In May this year, the NASA scientist revealed in a surprising way the moon shrinks "like a grape".
As the Moon's internal temperature cools, the outer layers retreat and crack, creating cracks and ridges along the surface.
This could be one of the processes behind the flashes studied by Professor Kayal.
And to better study lightning, the space expert and his team built a lunar telescope, which they installed in a Spanish observatory in April 2019.
Professor Kayal said: "The weather conditions for observing the moon are simply better than in Germany."
Better understanding these lightning bolts, added the expert, will help scientists who wish to install the Moon in the future.
