On December 21, 2012, the winter solstice sun will rise between the astronomical constellations of Sagittarius and Scorpio, which coincidentally is the black hole center of our Milky Way galaxy.
Here's what it would look like in space from the Earth's center:
Here's a diagram of Sagittarius pointing directly at the galactic center, Scorpio's tail. This area of the sky also has the ancient Greek name of Opiuchus, the serpent bearer. This area between Sagittarius and Scorpio was also associated with serpents to the Babylonians. Meso-american natives coincidentally named the dark rift as a great serpent swallowing it's own tail . . . the Ouroboros. The Ouroboros is believed to have been inspired by the Milky Way as some ancient texts refer to a serpent of light residing in the heavens.
This is from Wikipedia:
According to Roman era
mythography, the figure represents the healer Asclepius
, who learned the secrets of keeping death at bay after observing one serpent bringing another healing herbs. To prevent the entire human race from becoming immortal
under Asclepius' care, Zeus
killed him with a bolt of lightning
, but later placed his image in the heavens to honor his good works.
There is no evidence of the constellation preceding the classical era
. In Babylonian astronomy
, a "Sitting Gods" constellation seems to have been located in the general area of Ophiuchus. Gavin White proposes that Ophiuchus may in fact be remotely descended from the Babylonian constellation, representing Nirah
, a Babylonian serpent-god who was sometimes depicted with his upper half human but serpents for legs, perhaps identical with the constellation of Babylonian astronomy.
In medieval Islamic astronomy
, 10th century), the constellation was known as Al-Ḥawwaʾ
describes Ophiuchus as trampling on Scorpio
with his feet. This is depicted in Renaissance to Early Modern star charts
, beginning with Albrecht DÃ¼rer
in 1515; in some depictions (such as that of Johannes Kepler
, 1604), Scorpio also seems to threaten to sting Serpentarius in the foot. This is consistent with Azophi
, who already included ψ Oph
and ω Oph
as the snake-charmer's "left foot", and θ Oph
and ο Oph
as his "right foot", making Ophiuchus a zodiacal constellation
at least as regards his feet. This arrangement has been taken as symbolic in later literature, and placed in relation to the words spoken by God to the serpent in the Garden of Eden
It seems kinda far fetched that anything would happen. The Milky Way center is a long way from us and has little effect on Earth's affairs.
