Cosmobiology, also known as midpoint astrology, is a scientific discipline based on midpoints that has its origin in traditional astrology.
Astrology is the science of planetary and star interpretation related to human experience.
Reinhold Ebertin, a European scholar and physician, is considered the founder of the scientific discipline of Cosmobiology. His innovation and scientific approach, developed in the early 20th century, transformed traditional astrological interpretation.
In Cosmobiology, you work with a chart called the cosmogram and there are no houses or house systems. This is very different from Astrology which plots the planets on a horoscope in astrological houses.
Cosmobiology uses only 'hard aspects' or those in multiples of 45 degrees. This add greater impact and includes conjunctions, semi-squares, squares, sesqui-squares and oppositions. Astrology uses soft aspects such as sextiles and trines, along with the hard aspects.
Probably the biggest difference between the two systems is that in cosmobiology, you use planetary pictures for interpretation. The planetary pictures are called 'structures.' Each structure represents a tree with branches. The main stellar body is at the top and the midpoints fall llike branches beneath.
The following is an illustration of the structure of Moon in a chart:
Saturn ------|------ Ascendant
Uranus ------|------ Ascendant
Pluto ------|------ Node
Mars ------|------ Pluto
The principle of each stellar body is emphasized Cosmobiology, compared to Astrology which emphasizes individual aspects.
