The bizarre phenomena were observed from Earth by the Moon Impacts Detection and Analysis System (MIDAS) on the nights of July 17 and July 18.
MIDAS observatories in Spain scan the surface of the Moon on a daily basis, in search of asteroid and meteor impacts.
A European Space Agency (ESA) statement revealed the flashes were registered almost exactly 24 hours apart, “seemingly in pursuit” of one another.
Detailed photographs of the Moon’s bumpy surface, captured by high-sensitivity CCD cameras, show the exact moment of impact.
But could this footage be the evidence UFO hunters need to finally settle the debate on whether alien visitors to Earth exist or not?
It is extremely unlikely the lunar photos have anything to do with aliens but both MIDAS and the ESA agree the flashes were very much extraterrestrial in origin.
The ESA said: “On July 17, 2018, an ancient lump from space thwacked into the Moon with enough energy to produce a brilliant flash of light.
“With another rock seemingly in pursuit, a second flash lit up a different region of the Moon almost exactly 24 hours later.”
Despite the force of impact, current estimates suggest the foreign impactors were no larger than the average walnut.
Space rocks of this size dubbed meteoroids are typically remnants of bigger asteroids and comets drifting aimlessly through space.
The flashing meteoroids in question most likely originated from the dusty comet trail left behind in the wake of the Alpha Capricornids meteor shower.
The Alpha Capricornids shower usually starts as early as July 15 and continues until mid-August.
The ESA said: “For at least a thousand years people have claimed to witness short-lived phenomena on the face of the Moon.
“By definition these transient flashes are hard to study, and determining their cause remains a challenge.”
Three astronomical observatories in Spain scan the Moon for the transient flashes on behalf of the MIDAS project.
The observatories use powerful telescopes and CCD cameras to detect and identify the various impacts that rock the glowing orb.
Jose Maria Madiedo, MIDAS, said better understanding these lunar impacts can help better protect Earth from similar dangers.
The space expert said: “By studying meteoroids on the Moon we can determine how many rocks impact it and how often, and from this we can infer the chances of impact on Earth.”
