A lunar eclipse is nothing unusual. Habitually. But the one due on July 28 is somewhat different. It will fall under the shadow of the Earth for four hours
The entire eclipse – when the veil of the Earth's shadow completely erases what would otherwise be the silver surface of the Moon – will last one hour and 43 minutes
. It is the longest lunar eclipse to be experienced this century
And most of the world will see the light of day.
While the best observation will be from East Africa, the Middle East and some parts of Europe and Asia,
The moon will be low on our horizon when it begins to darken it
And it will fold completely submerged in a reddish stain
This is because the only sunlight reaches the moon will bounce from the upper atmosphere of the regions experiencing the sunset or the Sunrise. And just as these daily events are accompanied by the reddish hues of refracted sunlight, it is what will reach the moon.
Lunar eclipses generally last much longer than their solar counterparts. The shadow worn by the moon is much smaller than that produced by our own planet.
The result is usually that a solar eclipse is only seen by a relatively small number that falls under the masking orb of the moon. But the nocturnal transformation of the moon into red blood orb can be seen by anyone on Earth while it's dark.
A super blue blood moon earlier this year has earned its attractive name through a series of coincidences. He was closer to Earth than usual (which you will not notice). It was also the second full moon of the month (an artifact of our Gregorian calendar).
But it was red. And that makes him scary.
This time, the moon will be at its apex – the furthest point from Earth's orbit. This means that it will cross the space at a point where the cone of the Earth's shadow is wider – making the eclipse longer.
According to NASA, its duration of one hour 43 minutes is only four minutes of its maximum duration. 19659004] This story was originally published in news.com.au.
