Скачать или смотреть BLOOD MOON Timelapse: The Total Lunar Eclipse

Due to its reddish color, a total eclipse of the moon is sometimes referred to as a blood moon. In addition, in the 2010s the media started to associate the term "blood moon" with the four full moons of a lunar tetrad, especially the 2014-2015 tetrad coinciding with the feasts of Passover and Tabernacles. A lunar tetrad is a consecutive sequence of four lunar eclipses, spaced six months apart.

On April 15, 2014, there was a total lunar eclipse which was the first of four consecutive total eclipses in a series, known as a tetrad; a second one took place on October 8, 2014, the third one on April 4, 2015 and the remaining one took place on September 27, 2015. It is one of eight tetrads to take place during the 21st century AD. As with most lunar eclipses, the moon appeared red during the April 15 2014 eclipse. The red color is caused by Rayleigh scattering of sunlight through the Earth's atmosphere, the same effect that causes sunsets to appear red.[2] Hagee also connects the solar eclipse of March 20, 2015 in the middle of the sequence.

The total eclipse will last only five minutes.

For a total lunar eclipse to happen, the Moon must be full, which means it is directly opposite the Sun, with Earth in between. The eclipse happens when the Moon moves into the shadow cast by the Sun shining on Earth. We don't have an eclipse every month because sometimes the Moon is above the shadow, sometimes below.

During the eclipse, the Moon often looks reddish because sunlight has passed through Earth's atmosphere, which filters out most of its blue light. This eerie, harmless effect has earned the tongue-in-cheek nickname "blood moon."

A telescope is not needed to view a lunar eclipse-- just find the Moon in the sky and enjoy.
