Galactic Centre

The centre of our Galaxy, the Milky Way, currently located at Sag 26°56'. This point, discovered in 1932, is thought to contain a massive black hole with the mass of some four million times that of our own Sun. It has a significant effect when aspected, inclining people to take a central role in affairs and to have a sense of cosmic destiny.

Galaxy

A vast grouping of billions of stars and associated cosmic phenomena bound together by gravity and orbiting a common centre. According to science, billions of galaxies thousands of light-years in diameter are scattered across the universe, with pretty well nothing much occupying the vast space between them (unless of course you count the so-called "dark matter" postulated by the latest cosmological theories). Almost all of the visible stars in the night sky, including our own Solar System, are part of the Milky Way Galaxy. Most galaxies external to our own require a telescope to see clearly. Notable exceptions are the Large and Small Magellanic Clouds and the Andromeda Galaxy, which are visible to the naked eye. Galaxies as such have no astrological significance, though esoteric teachings hold that they are each a "body" of a divine being.

Geocentric Model of the Universe

Dominant classical view of the universe developed by in the 5th Century BC by Plato and systematised by Aristotle, wherein the Earth held the central position. The planets and fixed stars were believed to revolve around a spherical Earth, affixed to crystalline spheres. Ptolemy in the 2nd Century AD developed a scientifically refined version of this system, which held sway until the 17th Century, when it began to be replaced by the modern Heliocentric Model developed by Galileo, Copernicus and Kepler. See Ptolemy.
