Nestled in the heart of the North Atlantic, Iceland enchantingly presents one of nature's rarest and most breathtaking phenomena: the Super Blue Blood Moon. This celestial trifecta occurs when a total lunar eclipse coincides with the second full moon of the month, also known as a 'Blue Moon', during the moon's closest approach to Earth, or 'Supermoon'. The result is a visually stunning spectacle that transforms the moon's customary silver glow into a mesmerizing reddish hue, earning it the aptly captivating moniker, Super Blue Blood Moon.
On January 31, 2018, skygazers worldwide turned their eyes towards the heavens, but none more eagerly than the residents of the self-proclaimed 'Land of Ice and Fire'. With its high latitude and northerly location, Iceland's vantage point offered an unparalleled view of this extraordinary astronomical event, drawing both locals and visitors alike to its shores for an unforgettable celestial encounter.
Understanding the Super Blue Blood Moon
The Super Blue Blood Moon is not merely a matter of serendipitous timing. Each of its constituent parts possesses its unique character and significance, contributing to the arresting beauty of this astronomical marvel.
Intriguingly, the rare alignment of these celestial events occurs under conditions that, while not impossible, are certainly infrequent, making the Super Blue Blood Moon a genuinely remarkable occurrence.
The 'Supermoon' Secrets
When the full moon's orbit brings it closest to Earth, it appears larger and brighter in the night sky, earning the name 'Supermoon'. At its perigee, this celestial body can appear up to 14 percent larger and 30 percent brighter than at its apogee, the most distant point in its monthly journey around our planet.
The Supermoon brings a striking grandeur to the night skies, its impressive size and luminance casting a palpable, ethereal glow upon the landscape below. In Iceland, this dramatic enhancement of the lunar presence lent an otherworldly aspect to its rugged, volcanic terrain, as if the very mountains themselves were illuminated from within.
The 'Blue Moon' Conundrum
Contrary to its name, the 'Blue Moon' is not an exceptionally rare occurrence. Rather, it is the second full moon in a single calendar month, a phenomenon that happens approximately every 2.7 years. This rendering of the moniker hails from the 19th century, deriving humorously from the phrase "once in a blue moon", used to describe something that happens very rarely.
In Iceland, the Blue Moon'splacement within this lunar sequence provided a superb opportunity for astronomers and enthusiasts to indulge in consecutive full moon observations, comparing notes on their respective sightings and marveling at the subtle variations in the moon's appearance that accompanied each successive lunar phase.
The Canvasing Cosmic Spectacle
As the sun dipped below the horizon, all eyes turned to the east, eager to witness the initial stages of the celestial evento unfold. The senses were quickly rewarded as the fully illuminated Super Blue Blood Moon began its transit through the cosmos, eclipsing the intervening planets and stars and casting a decidedly lunar dominance over the night sky.
The evening's experience was not confined to eye-watering crescendos, however. As the moon progressed through the Earth's shadow, shades shifted and hues deepened, painting an ever-changing tapestry of cosmic color against the jet-black night.
The Eclipse Progression
Throughout the night, the moon traversed the Earth's penumbra, the outer portion of its shadow, before plunging into the umbra, the inner core where the Earth entirely obscures the sun's light. Here, the Super Blue Blood Moon underwent its most profound transformation, as the celestial body adopted a mesmerizing reddish hue, baptized into its new apellation by the celestial connoisseurs below.
The reddish coloration, known as the lunar ' Durham', is a result of Rayleigh scattering, the same optical phenomenon responsible for the Earth's blue skies. As sunlight passes through the Earth's atmosphere, the shorter, blue wavelengths are scattered by Earth's atmosphere, allowing only the longer, red wavelengths to reach the moon's surface, casting it in an eerie blood-red glow.
The Icelandic advantage
Standing at the planet's threshold, the inhabitants of this volcanic isle experienced the eclipse in all its glory. As the Super Blue Blood Moon slowly began to wane, the darkening lunar face reflected the planet's fiery spirit, providing a poignant and memorable juxtaposition of the celestial and terrestrial.
With its wide-open spaces, innumerable lava fields, geothermal pools, and dramatic coastlines, Iceland offered unrivaled opportunities to appreciate the astounding spectacle as the Super Blue Blood Moon hung low over the frostbitten landscape, painting an ethereal tableau of celestial beauty.
As the moon emerged from the Earth's shadow and resumed its dominant nocturnal role, thoughts turned from the past to the future. The experience of the Super Blue Blood Moon served as a powerful reminder of the cosmos' boundless wonders, fueling enthusiasm and determination to capture every possible celestial moment. For the residents of Iceland, the opportunity to experience such a remarkable spectacle was a gift they will cherish for a lifetime.
