Sky
watchers and observers of the lunar system will notice an extremely rare cosmic
sight on Wednesday, October 8, when a total lunar eclipse is expected to occur
in different parts of the World.
The total
eclipse of the moon will result in a clash simultaneous rising of the sun in
what scientists have called “selenelion,” a phenomenon that celestial geometry
says cannot happen.
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
images of both the sun and moon are expected to be lifted above the horizon by
atmospheric refraction. This will allow people on Earth to see the sun for
several extra minutes before it actually has risen and the moon for several
extra minutes after it has actually set.
As a
consequence of this atmospheric trick, watchers in different locations will
have a chance to observe this unusual sight firsthand, with the possibility of
simultaneously seeing the sun rising in the east while the eclipsed full moon
is setting in the west.
If you want to witness this, just be an early riser tomorrow morning
