Story summary

Transient lunar phenomena (TLPs) are brief flashes of light on the Moon, first documented in 1787 by astronomer William Herschel.
TLPs can last from milliseconds to hours, with quick flashes often caused by meteoroid impacts and longer lights linked to radon gas from moonquakes or solar wind interacting with lunar dust.
The European Space Agency's NELIOTA project has recorded nearly 200 lunar impact flashes, revealing patterns in their occurrence.
Despite extensive research, the exact causes of TLPs remain uncertain, and some researchers dispute the existence of long-lasting events.
