Vanishing act: Exploring the case of the disappearing moon

The kinship between the Earth, moon and sun has been documented since the beginning of time. The welcoming golden light of the sun greets humanity and serves as the click of a new day, while the eerie white glow of the moon sends the homo race into its nightly sleep .
But what if there was a day when one occurred without the other ? What if that day became weeks or even months ? ad

such an occurrence took place about a millennium ago, as Earth ‘s moon disappeared from view during the month of May in the class 1110, with nary a argue given for the strange phenomenon. The unusual occurrence puzzled those who lived through it and continued to baffle astronomers throughout the ages. There was a impression that the moonlight ‘s disappearance was the consequence of an eclipse .
The british astronomer George Frederick Chambers wrote about the celestial mystery in his 1899 koran The Story of Eclipses. About 800 years after it happened, Chambers pegged the date of the overshadow as having occurred on May 5, during the reign of Henry I. ad “ The sum occurred before midnight, ” Chambers wrote of the moon ‘s disappearance from the night flip, adding that it was “ apparent that this was an example of a ‘black ‘ overshadow when the moon becomes quite inconspicuous alternatively of shining with the conversant coppery imbue. ”
But is that truly what happened ?
Finding out the solution of the lunar absence became the work of a 2020 survey in the journal Scientific Reports, leading to a more complex answer than originally thought .
The previously agreed-upon conclusion was that an eruption at Iceland ‘s Mount Hekla was the perpetrator. Hekla, located in the southerly end of Iceland, was referred to as the “ Gateway to Hell ” by Europeans during the Middle Ages due to its frequent eruptions .
When an eruption took position at Hekla on approximately Oct. 15, 1104, sulfur-rich particles launched into the stratosphere . For many years, this event was thought to be the catalyst for the moon ‘s apparent disappearance.

The Scientific Reports study, led by a team from the University of Geneva in Switzerland, began to unravel new information into the lunar month ‘s whereabouts. To see whether the Hekla eruption was the lone causal agent of the fade, the researchers analyzed ice cores from Iceland and Antarctica, and finally determined that the date of the Hekla eruption did not line up with the 1110 timeline of lunar absence. ad To find the true source, researchers combed through the records of medieval times for any references made to a “ blue lunar eclipse ” or a “ black eclipse. ” After pouring over many a bible, the team made a breakthrough with the trace 1110 introduction from The Peterborough Chronicle : “ [ The moon ] was then wholly extinguish withal, that neither light, nor ball, nor anything at all of it was seen. ”
Knowing the lunar absence began around 1110, the team suggests a bunch of volcanic eruptions from between 1108 and 1110 was most likely the root cause, not the 1104 Hekla eruption as previously thought .
One of these oft-forgotten eruptions took target in 1108 in Honshu, Japan. A diary entrance from a japanese statesman, uncovered by researchers and cited in the Scientific Reports study, said that an eruption of Honshu ‘s Mount Asama began in deep August of 1108 and continued through that October .
“ On August 29, there was a fire at the peak of the volcano, a thick layer of ash in the governor ‘s garden, everywhere the fields and the rice fields are rendered unfit for cultivation, ” the introduction read. “ We never saw that in the country. It is a identical strange and rare thing. ” ad

The 1108 eruption at Asama, known as possibly the most significant in the volcano ‘s history, is one of what the sketch called “ respective major volcanic events ” that is reproducible with the “ stratospheric aerosol loading sufficient to induce ” the dark eclipse. Observations of changes to the moon, such as the dark, entire lunar eclipse, a well as observations of dimming or discoloration of the sun, are major corroborators of the time of major explosive volcanic activity .
On top of the overshadow, the 1108-1110 eruptions led to several social impacts in Europe, peculiarly in agribusiness. The researchers ‘ work revealed descriptions of an abundance of severe upwind conditions, crop failures and famines compared to other years with exchangeable volcanic events.Losing the lunar association between Earth and the moon had several negative side effects, making the bright nightly appearance missed all the more .
