Eclipse 2018: How the Blood Moon changes to red color in the lunar eclipse | Science | New

The Moon of Blood will illuminate the night sky over the Earth in the last hours of Friday, July 27th.

During the eclipse, the moon crosses the center of the Earth, the darkest shadow, and disappears briefly

But rather than disappearing completely from the sky for a period of time, the full moon will take a deep red to deep orange color.

The bizarre Blood Moon show will be visible through the largest eclipse set that will last about an hour and 43 minutes

But why does the moon change color during a total lunar eclipse?

A lunar eclipse occurs whenever the moon and the sun align perfectly on the star planes with the right earth. In the middle of the two

In this position, the Earth darkens all the sunlight falling on the moon, producing a dark shadow cone extending into space.

It would be logical to assume that the moon will remain enveloped in the moon. shadow but a light tower, known Rayleigh Scattering illuminates the red moon

Throughout the eclipse, the sun's rays projected by the sun are curved and scattered around the earth's atmosphere.

The scattering light filters certain bands of color on the visible spectrum, such as blue, leaving the least affected colors such as red and orange falling on the moon.

According to NASA's Goddard Space Flight Center, if you were to look at the Earth from the surface of the moon, the Earth would be surrounded by a bright crown of orange light – every sunrise and sunset on the edge of the planet.

The US Space Agency said: "When the moon passes in the central part of the shadow, called the shadow, it sinks dramatically.]" Once that " it is entirely in the shadow, the moon appears dark red because of the sunlight scattered in the Earth's atmosphere. "In fact, if you look at the eclipse of the surface of the moon, you will see the sun go down behind all the Eart h, bathing you in a warm red glow. "

The same diffusion of light is responsible for the blue color of the sky, the color of the blue eyes and the sunsets of orange sun.

Rayeigh Scattering is named after the 19th century British scientist Lord Rayleigh

Richard Fitzpatrick, professor of physics at the University of Texas at Austin, explained: "When the sun is down in the sky, it seems less bright, because of the atmospheric diffusion. "

appears redder than normal, because more blue light than red light is scattered by the sun's rays, leaving an excess of red light. "Similarly, when we look at the sky, it does not appear black because of" Again, since the blue light is scattered more effectively than the red light, there is an excess of blue light scattered to the down, and so the sky appears blue. "

The integrity of the Moon of Blood is also affected by other factors such as atmospheric conditions and the amount of dust in the air.
