According to the Sky website, the blue moon is visible at 19:10 EDT on August 30, or 6:10 a.m. Vietnam time on August 31. Biggest and brightest full moon is on August 30 at 9:36 p.m. EDT, or August 31 at 8:36 a.m. Vietnam time.
According to NASA, this is a very rare occurrence. The next blue moon is not expected to appear again until 2037.
Retired NASA astronomer Fred Espenak explains: It’s called a supermoon because it reaches its closest point to Earth in its orbit, known as perigee, and becomes the largest and brightest moon in the universe.
At a distance of 364,000 km from our planet, the Moon appears about 7% larger than a normal full moon.
Similar to the names of strawberry and pink moons, blue moons are not named for their color. The moon is still greyish-white, but is the brightest moon of the year.
according to the magazine business Insider, Name The Blue Moon was linked to an event in 1883. At that time, on the day of the Super Moon, a deadly volcanic eruption on the island of Krakatoa (Indonesia) killed 36,000 people. Compounds of sulfur dioxide and ash fill the air, causing the Moon to appear blue because volcanic smoke particles block red light without blocking other colors.
According to London’s Natural History Museum, wildfires can also cause blue moons.
Currently, a blue moon is defined as the second full moon to occur in a month. August 30 will be the second full moon of August. Last August 1 is the first full moon of the month.
If the forecast isn’t clear on August 31, don’t despair, because according to officials, “the moon will appear round for 3 days around the full moon from August 30 to September 1.”
