The mystery of the moon's complete disappearance from the sky in the year 1110.. A study reveals the secret behind it

<p style=";text-align:left;direction:ltr">Arab Weather - Scientists from the University of Geneva in Switzerland were able to solve the mystery of the strange phenomenon that has puzzled astronomers for more than a thousand years, which is the complete disappearance of the moon from the sky in the year 1110. Unlike any other lunar eclipse, no trace of the moon appeared that night, which raised long questions.</p><p style=";text-align:left;direction:ltr"> The study, published in Scientific Reports, suggests that the event was likely <strong>the result of volcanic aerosol</strong> .</p><h2 style=";text-align:left;direction:ltr"></h2><h2 style=";text-align:left;direction:ltr"> Black Moon Eclipse</h2><p style=";text-align:left;direction:ltr"> By analyzing ice cores and tree rings, the researchers discovered that 1109 was significantly cooler than the year before, suggesting a thin layer of particles hanging in the atmosphere. The team believes that a series of volcanic eruptions at the time released dust and sulfur into the atmosphere, leading to the darkening of the moon during the eclipse in May 1110, as recorded by a writer in the Peterborough Chronicle.</p><h2 style=";text-align:left;direction:ltr"> The disappearance of the moon in historical documents</h2><p style=";text-align:left;direction:ltr"> The Anglo-Saxon Chronicle documented the complete disappearance of the moon on May 5, 1110, with the chronicler writing: &quot;On that night the moon appeared bright, but soon its light faded, and by night it was entirely gone.&quot; Centuries later, English astronomer George Frederic Chambers described the event as a &quot;black eclipse&quot; in which the moon disappeared entirely rather than appearing its usual copper color.</p><ul style=";text-align:left;direction:ltr"><li style=";text-align:left;direction:ltr"><h3 style=";text-align:left;direction:ltr"> The role of Mount Asama volcano</h3></li></ul><p style=";text-align:left;direction:ltr"> Scientists have been trying to pinpoint the volcano responsible for the phenomenon, and they believe Mount Asama in Japan is the culprit. Its massive eruption in 1108, which lasted for several months, is believed to have released huge amounts of dust and sulfur into the atmosphere, causing widespread climate change. A diary from 1108 refers to “fire at the summit of the volcano” and the destruction of rice fields. </p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"><img alt="" src="/sites/default/files/uploads-2020/In%20the%20year%201110%2C%20the%20moon%20completely%20disappeared%20from%20the%20sky..%20A%20recent%20study%20explains%20the%20reason.jpg" style="width: 800px; height: 475px;" /></p><p style=";text-align:left;direction:ltr"></p><ul style=";text-align:left;direction:ltr"><li style=";text-align:left;direction:ltr"><h3 style=";text-align:left;direction:ltr"> The catastrophic effects of a volcanic eruption</h3></li></ul><p style=";text-align:left;direction:ltr"> Historical documents support the hypothesis that a series of volcanic eruptions in 1108–1110 AD caused severe weather, crop failures, and famine across large areas of western Europe. Researchers suggest that these volcanic eruptions, which have received little attention until now, were behind the extreme weather events and the disappearance of the moon in 1110.</p><p style=";text-align:left;direction:ltr"> The study confirms that volcanic events during this period had a profound impact on humanity, and rediscovers these forgotten events. Evidence suggests that volcanic dust over Europe in May 1110 contributed to a total dark lunar eclipse, confirming the revised chronology of ice cores, which indicate several successive volcanic eruptions between 1108 and 1110 AD.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> See also:</p><p style=";text-align:left;direction:ltr"> <a href="https://www.arabiaweather.com/ar/content/%D9%82%D9%85%D8%B1-%D8%A7%D9%84...
