Why does the moon turn red during an eclipse? This is when the next eclipses

During a lunar eclipse, the moon's face will take on a red tinge. The fiery glow is most dramatic during a total lunar eclipse, but even during partial and half lunar eclipses, our single satellite takes on a maroon color.

When the moon descends on the outer part of the Earth's shadow, sinking completely into the darkest part of that shadow, why is the result not a "dim light" for the sky? Why instead is the moon covered by a light orange glow in blood red?

Perhaps intuitively, the phenomenon that explains why the sky is blue is the same one that turns our moon red during a lunar eclipse. This phenomenon is called Rayleigh scattering, or the preferential scattering of certain wavelengths of light by adolescent particles - those that are about one-tenth the wavelength of light or less. During the day, sunlight waves - which consist of a band of colors corresponding to their individual wavelengths - are filtered through our atmosphere, where small molecules of nitrogen and oxygen gas allow longer wavelengths as red, orange and yellow. But shorter wavelengths, such as purple and blue, are absorbed and then scattered on each side, giving them more chances to hit our eyes.

Here is how the same phenomenon of light scattering makes our moon look red. During a total lunar eclipse, the sun, Earth and moon are perfectly aligned in that order. When the Earth is directly in front of the sun, it blocks sunlight from illuminating the moon. At that moment, you would see a ring of light around the moon, because although our planet is much larger than the sun, the light of our native star bends around the edges of the Earth. This light is reflected in the moon.

"The darkened Earth disk is surrounded by every sunrise and every sunset in the world, all at once," according to NASA. However, sunlight must pass through the Earth's atmosphere before it hits the moon. Along the way, the blue light with the shortest wavelength is scattered before it reaches the Moon, leaving undamaged reds and oranges to wash the moon's surface. And lo and behold, a red moon is created.

Sunrises and sunsets take on reddish hues for this reason: "When the sun is higher in the sky during the day, the red light passes directly to the ground. As the blue light is scattered and therefore more likely to be in line your vision, ”astronomer Shannon Schmoll, director of the Abrams Planetarium at Michigan State University, told Live Science in an email.

"Në perëndimin e diellit, meqenëse dielli është i ulët në qiell, drita e kuqe kalon në vijën tuaj të shikimit, ndërsa bluja shpërndahet larg saj", shtoi ai.

Hëna do të ndryshojë nuanca të ndryshme gjatë fazave të ndryshme të një eklipsi total hënor, duke u shndërruar nga një gri fillestare në portokalli dhe qelibar. Kushtet atmosferike gjithashtu mund të ndikojnë në shkëlqimin e ngjyrave. Për shembull, grimcat shtesë në atmosferë, të tilla si hiri nga një zjarr i madh ose një shpërthim vullkanik i kohëve të fundit, mund të bëjnë që hëna të shfaqet një nuancë më e errët e kuqe, sipas NASA-s.

Hëna jo gjithmonë fshihet plotësisht pas hijes së Tokës. Gjatë eklipseve të pjesshme hënore, dielli, Toka dhe hëna janë paksa të shkëputura në shtrirjen e tyre, dhe kështu hija e planetit tonë përfshin vetëm një pjesë të hënës.

A novice sky observer may not even notice the third type of lunar eclipse, the penumbral one, in which the moon sits on half the earth, or its faint outer shadow.

To see this atmospheric science in action, look no further than the longest partial lunar eclipse of the century, which is due to the ash of the sky between November 18 and. 19. The fiery moon will be visible in all 50 US states.

The next two lunar eclipses will be total eclipses and will occur on May 16, 2022 (visible in America, Europe and Africa), followed by one on November 8, 2022 (visible in Asia, Australia, Pacific and America), according to NASA.
