In the month of July, the human beings would be the witness to one of the rarest astronomical events which is known as the 'blood moon'. It will be the second blood moon of the year which would be seen on the night of 27th and 28th July. It is going to be the longest lunar eclipse of the 21st century.
This is going to be another special and one of the rarest event that will be occuring in the same year, after super blue blood moon which occurred on 31st January. This super blue blood moon was an event which was a combination of supermoon, blue moon and the blood moon.
We have few reasons why this Lunar Eclipse is going to be a special and the rarest one.
LONGEST ECLIPSE OF THE CENTURY
Believing the sources, this lunar eclipse would last for a total of 103 minutes, i.e. 1 hour and 43 minutes, making it 40 minutes longer than the January eclipse. Apparently, the January eclipse was supposed to be the longest one of this century, but this eclipse would surpass the former.
REASON OF THE MOON BECOMING RED
The blood moon or the 'full buck moon' as is being called will become red whilst the eclipse beause of the way in which the light would bend around the atmosphere of the Earth. DUring this event, the moon would turn orange and not disappear completely when it crosses throught the shadow which would cast by Earth. This eccentric effect is called as ‘Rayleigh scattering’ which filters the bands of greena nd violet light present in the atmosphere during an eclipse.
REASON OF BEING THE LONGEST ECLIPSE
The full moon will pass through the shadow of the Earth, making it last for a much longer time than usual. During the same time, it will also be at the utmost distance from the Earth. Therefore, this is the reason why it would take longer to cross the shadow of the Earth.
PLACE WHERE THE ECLIPSE WOULD BE VISIBLE
The eclipse can be seen in the eastern hemisphere of the world only, i.e. Europe, Asia, Africa, Australia and New Zealand. People living in NOrth America and Arctic Pacific area will not be able to see the event.
People in Asia, Australia and Indonesia will be able to see it during the morning hours, where as people in Europe and Africa will be able to see it during the evening time between sunset and midnight on 27th July.
