As far as lunar events go, a single phenomenon usually draws crowds to gaze upwards at a specific time. But on January 31, the world was captivated by a rare lunar "trifecta" – where three phenomena occurred all at once. The "super blue blood moon" was visible over several continents, comprising a total lunar eclipse, a super moon and a blue moon. In some regions of the world, it was the first such event in 150 years – but not in the Middle East. The last time this part of the world saw a super blue blood moon was on December 30, 1982. Regardless, it's a rare event. Once in a (super) blue (blood) moon, some might say. <strong>What is a super blue blood moon?</strong> A <strong>super moon</strong> is a full moon that appears larger than usual, because the moon is at its closest distance to Earth. Of the dozen or so new moons that occur each year, <a href="https://www.thenational.ae/world/supermoon-rises-above-uae-and-around-the-world-in-pictures-1.681176">two or three will become super moons.</a> A <strong>lunar eclipse</strong> occurs when the moon passes directly behind the Earth – into its shadow – and can only happen when the sun, Earth and moon are perfectly aligned, with the Earth in the middle. The last partial eclipse in the <a href="https://www.thenational.ae/uae/lunar-eclipse-puts-on-dazzling-celestial-display-in-pictures-1.617732">Emirates was in August</a>. This is not to be confused with a solar eclipse, which is when the moon is in the middle, blocking the sun. As the moon takes its place in the Earth's shadow, it will take on a reddish hue – which is where the <strong>blood moon</strong> comes in. A <strong>blue moon</strong>, although the subject of a popular idiom you've likely heard from your mother on the rarity of an event, is arguably the most common occurrence. Its two definitions are used almost interchangeably – as the third full moon in a season that has four full moons, or the second full moon in a calendar month – and it has absolutely no correlation to the actual colour of the moon. _________________ <strong>Read more:</strong> <strong><a href="https://www.thenational.ae/uae/environment/super-blue-blood-moon-in-the-uae-in-pictures-1.700705">Super blue blood moon in the UAE - in pictures </a></strong> <strong><a href="https://www.thenational.ae/uae/podcast-uae-in-a-minute-for-january-31-2018-1.700503">PODCAST: UAE in a minute for January 31, 2018</a></strong> _________________
