What is a blue moon and when will it happen?

<p style=";text-align:left;direction:ltr">Weather of Arabia - This year we will witness a distinct astronomical phenomenon, which is the &quot;blue moon&quot;. Here is everything you need to know about this moon</p><p style=";text-align:left;direction:ltr"> &quot;When the moon is blue&quot; is a phrase used to describe a very rare event, but what does it mean in astrological terms? Can the moon really turn blue?</p><p style=";text-align:left;direction:ltr"> The truth is that there are two types of blue moons, but unfortunately; Neither of them have anything to do with blue </p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"><img alt="" src="https://cdn.pixabay.com/photo/2019/08/20/09/04/landscape-4418215_1280.jpg" /></p><p style=";text-align:left;direction:ltr"></p><h3 style=";text-align:left;direction:ltr"> <strong>The blue moon has two types</strong></h3><p style=";text-align:left;direction:ltr"> <strong>A seasonal blue moon</strong> is a traditional term for a blue moon and refers to the third full moon in a season that has four full moons according to NASA, while its second definition - a misunderstanding of the first definition - is <strong>a monthly blue moon</strong> that refers to the second full moon in a month according to &quot; time and diet</p><p style=";text-align:left;direction:ltr"> Currently the second expression is used as a definition of a blue moon rather than being an erroneous definition.</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> Since the cycle of the moon phases is about a month long, we usually see <strong>12 full moons each year</strong> . Many cultures have given distinct names to each month&#39;s full moon; Which means 12 months, 12 full moons, 12 distinct names. It sounds simple right?</p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> <strong>Well, not exactly, this is where the blue moon comes into the equation.</strong></p><p style=";text-align:left;direction:ltr"> The moon phases actually take 29.5 days to complete, which means it only takes 354 days to complete 12 lunar cycles, so every 2.5 years or so a 13th full moon is observed during a calendar year, and this 13th full moon does not correspond to the naming system. It is referred to as a blue moon. </p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"><img alt="" src="https://cdn.pixabay.com/photo/2019/02/11/14/38/mountain-3989829_1280.jpg" /></p><p style=";text-align:left;direction:ltr"></p><h3 style=";text-align:left;direction:ltr"> <strong>How often does a blue moon occur?</strong></h3><p style=";text-align:left;direction:ltr"> Contrary to the popular phrase &quot;once in a blue moon&quot;, a blue moon can occur relatively frequently, that is, in astrological terms. We see a blue moon every two to three years, according to NASA.</p><p style=";text-align:left;direction:ltr"></p><h3 style=";text-align:left;direction:ltr"> <strong>What is the black moon?</strong></h3><p style=";text-align:left;direction:ltr"> Since there are approximately 29.5 days between full moons, February will not have a blue moon month because it only has 28 days in a regular year and 29 in a leap year. Sometimes the month of February does not witness a full moon at all, and this is what is known as the black moon. </p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"><img alt="" src="https://cdn.pixabay.com/photo/2016/11/23/17/13/dark-1853877_1280.jpg" /></p><p style=";text-align:left;direction:ltr"></p><h3 style=";text-align:left;direction:ltr"> <strong>When will we see the next blue moon?</strong></h3><p style=";text-align:left;direction:ltr"> The next monthly blue moon will be on August 30/31, 2023, while the next seasonal blue moon will be on August 19/20, 2024.</p><p style=";text-align:left;direction:ltr"></p><h3 style=";text-align:left;direction:ltr"> <strong>When did we last see a blue moon?</strong></h3><p style=";text-align:left;direction:ltr"> The last blue moon was on August 22, 2021 </p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"><img alt="" src="https://cdn.pixabay.com/photo/2016/08/18/08/27/water-1602305_1280.jpg" /></p><p style=";text-align:left;direction:ltr"></p><h3 style=";text-align:left;direction:ltr"> <strong>Can the moon turn blue?</strong></h3><p style=";text-align:left;direction:ltr"> Yes, it is possible, but this is a very rare event, and here, you could say that it happens <strong>&quot;once in a blue moon.&quot;</strong></p><p style=";text-align:left;direction:ltr"></p><h3 style=";text-align:left;direction:ltr"> <strong>When did the moon become blue?</strong></h3><p style=";text-align:left;direction:ltr"> According to NASA, in 1883, an Indonesian volcano called Krakatoa erupted and sent ash up to 50 miles (80 kilometers) into the atmosphere. Tiny ash particles acted as a filter, scattering the red light <strong>and turning the moon a distinct blue-green colour.</strong></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"></p><hr /><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"> Source: <a href="https://www.space.com/15455-blue-moon.html">www.space.com</a></p><p style=";text-align:left;direction:ltr"></p><p style=";text-align:left;direction:ltr"></p>
