Arab Weather - The Earth's sky will witness the full moon of the month of Safar next Monday, as its brightness will reach 100%. It is called a "blue moon" because it is the third of four full moons during the Northern Hemisphere summer season, although it will not appear blue. Dr. Ashraf Tadros, professor of astronomy at the National Research Institute of Astronomy and Geophysics, told the Middle East News Agency that blue moons occur at a rate of approximately once every two and a half years, which led to the emergence of the term “once in a blue moon” to indicate their rarity. He added that the moon will rise on that day immediately after sunset, and will remain visible in the sky throughout the night until it sets with the sunrise the next morning. Since the naked eye cannot distinguish a true full moon, it will appear to us as a full moon from August 18 to 21.

Although the moon can sometimes appear bluish, this only happens under certain atmospheric conditions. For example, a moon can appear blue when volcanic eruptions or fires release particles of a certain size into the atmosphere, favoring the scattering of red light. In 1883, the eruption of the Krakatoa volcano in Indonesia killed 36,000 people and sent huge amounts of sulfur dioxide and ash into the air. This volcanic dust blocked red light, making the moon appear blue, as other colors are naturally scattered. Forest fires, which are becoming more common with current climate change, can have a similar effect, according to the Natural History Museum in London.
