The Super Blue Moon Phenomenon Today... How Does It Affect Planet Earth?

Arab Weather - The moon is considered the permanent companion of planet Earth, and it is the closest celestial body to us. Today, Monday, the moon will reach its closest distance to Earth in a phenomenon known as the "supermoon."

What is a supermoon?

A supermoon occurs when a full moon coincides with an unusually close approach to Earth, a phenomenon that typically occurs three or four times a year due to the moon's changing elliptical orbit.

“A supermoon is not actually bigger, but it may appear that way,” said Noah Petro, project scientist for NASA’s Lunar Reconnaissance Orbiter. However, the difference in size may be so small that most people won’t notice it unless they compare multiple images of the full moon.

• When and where can you see the super blue moon?

There are four supermoons this year, and tomorrow's is called a "blue moon." The moon will be 224,917 miles (361,970 kilometers) from Earth, followed by another on September 17 at about 3,000 miles (4,484 kilometers) away. That night, the moon will experience a partial eclipse that will be visible across much of the Americas, Africa and Europe.

• Supermoon in the coming months

In October, the supermoon will be closest to Earth this year, at 222,055 miles (357,364 kilometers) away, followed by the November moon at 224,853 miles (361,867 kilometers).

• Link between the giant moon and earthquakes

Some people believe that the supermoon phenomenon may be linked to earthquakes, which is what Dutch earthquake forecaster Frank Hoogerbeets promotes. However, experts reject this unproven link.

“When the moon is at its closest distance to the Earth, the gravitational force is greater than usual, but the effect is limited to the famous tidal phenomenon only,” says Sherif El-Hadi, head of the seismology department at the National Research Institute of Astronomy and Geophysics. “There is no proven scientific relationship between the occurrence of earthquakes and the position of the moon or the sun.”

Has the moon really turned blue throughout history?

In the late 19th century, a historic volcanic event occurred that changed the geography and climate of the world. The eruption of Krakatoa in Indonesia in 1883 was one of the most destructive volcanic eruptions in modern history, and was associated with unusual climatic phenomena that affected the globe. What many people do not know is that this eruption had an unexpected connection to an astronomical phenomenon known as the “Blue Moon.”

The link between the Krakatoa eruption and the Blue Moon was indirect but striking. The volcanic ash that was thrown into the atmosphere after the eruption affected the quality of light reaching the Earth's surface, creating unusual visual effects in the sky. This color change and scattering of light was caused by the volcanic ash, which contributed to the unusual colors, including colors that could cause the Moon to appear blue or gray.
