Scientist have come open an say that A total eclipse of the moon on Wednesday, 8 october, will offer stargazers a rare chance to see both an eclipsed moon and a rising sun at the same moment, thanks to an optical trick played by the earth’s atmosphere.
It was gathered that During the lunar eclipse, the sun and moon will be
exactly 180 degrees apart in the sky. In a perfect alignment like this (called
a “syzygy”), such an observation would seem impossible.
The upcoming eclipse will be the second this year and part of a series
of four total lunar eclipses in 2014 and 2015. The hour-long event will be most
visible in the Western Pacific, Asian Far East, New Zealand and Australia’s
eastern coast.
However, observers east of the Mississippi River in the United States,
an area where the moon will only be partially visible when earth’s shadow
covers it, will be rewarded for braving the early hours of Wednesday just
before sunrise with a rare viewing of a selenation.
It’s a seemingly impossible occurrence when the eclipsed setting moon,
together with a rising sun, is visible in the sky simultaneously. The event
happens due to an atmospheric trick that refracts the light coming from the two
celestial bodies making them appear just over the horizon when in fact they are
just below it.
Depending on the location, there will be an open window of about 2 to 9
minutes when it will be possible to catch the rising sun in the east and the
eclipsed moon setting in the west. Seeing them would also require favorable
weather conditions and perhaps the use of binoculars or a telescope.
Also, the planet Uranus will be situated next to the moon during the
eclipse and should be bright enough to identify with binoculars.
ust 15 days after the sun, moon and Earth align on Wednesday, they will
do so again. On Oct. 23, the moon will pass in front of the sun, bringing a
partial eclipse to the Pacific Northwest.
