Sagittarius “A” Complex in Scorpio/Sagittarius, the Center of Our Galaxy
How did the ancient astronomers know the exact position of the center of our Milky Way Galaxy?
Paul LaViolette, Earth under Fire, tells us that the Ancients knew the exact center of the Milky Way Galaxy even though it is obscured by inter-stellar clouds of dust. The olden astronomers marked its location by the arrow-point (Arabic, Al Nasal) of the constellation Sagittarius shown by the orange-colored star Gamma Sagittarii (γ Sgr). Because our solar system moves; and the stars move –our long-term perspective of the universe changes slightly over time. 18,200 years ago Sagittarius’ arrow shaft pointed precisely toward the galactic center –which is quite astounding.
The first modern estimate of the Galactic Center was made by Harlow Shapley in 1917 by determining the 93 globular (dense ball-like) star clusters scattered uniformly around our galaxy. Knowing the position and distance of each cluster, he was able to make a three-dimensional map of their distribution, and from this he was able to determine the distribution’s center point. Shapley’s brilliant estimate was eight-times less accurate than the Ancients’ position recorded on Classical and Renaissance star maps. In 1931 Karl Jansky of Bell Laboratories detected the Galactic Center (GC) by observing the radio wave region of the electromagnetic spectrum (the GC is the brightest radio source in the sky). Eventually, in the mid 1960’s the GC was found to be within 0.04° of Sagittarius A.
The notion that the Milky Way is made up of a mass of stars was mooted by the Greek philosopher Democritus (400 B.C.). In 1610 AD this ancient idea was confirmed by Galileo with the use of his famous one-inch telescope. In 1543 Copernicus had proposed that our Sun lay at the center of our solar system. Then in 1917 Harlow Shapley discovered that our Sun is just one of multitudes of suns in the universe. In 1924 Edwin Hubble showed that there were countless spiral galaxies in the universe which were located beyond the limits of our own Milky Way spiral galaxy.
Some modern scientists suggest that our Galactic Center is a giant black hole –a gravitational singularity that voraciously gobbles up surrounding gas. But, LaViolette writes that ancient astronomers said that the Heart of the Galaxy is a womb where matter and energy are created, a cosmic wellspring giving birth to all the matter in the Galaxy. Cultures such as the Mexica-Maya-Andean group attributed great power to Scorpio/Sagittarius as part of the ressurrection cycle of the soul.
