The National Aeronautics and Space Administration (NASA) recently revealed the new Zodiac Signs starting this year, 2016. NASA said that there have to be changed on the 3,000-year-old astrological system.

The zodiac signs are the circle of the twelve divisions of celestial longitude employed by the western astrology and astronomy. About 3,000 years ago, the Babylonians divided the circle into twelve parts to make a whole astrological system. 

According to NASA, however, the change in the Zodiac Signs was something that needed to be done, simply because of sheer mathematics. “We didn’t change any zodiac signs, we [just] did the math,” NASA researcher Laurie Cantillo told BBC news.

NASA recently revealed the mathematical computations that lead to changes in the astrological Zodiac Signs. The 13th sign that was revealed to complete the revised Zodiac Signs is named Ophiuchus.

One of the things that really shocked horoscope enthusiasts about the readjustment was the insertion of a 13th sign, since the previous system, which used 12 signs, had been around for a very long time. With the 13th sign, all people who are born between November 29 and December 17 are Ophiuchus.

People under the new Zodiac Sign Ophiuchus are believed to be seekers of knowledge and wisdom. They are active, fascinating, impulsive, clever, and extravagant. However, they are also jealous, power-hungry, and sensitive. At their hearts, they were healers who hoped to one day rid the Zodiac of every ill — disease, violence, etc — and bring everyone closer together.

Ophiuchus is based on a constellation of the same name, which title is known as the Serpent-bearer in Greek. The new Zodiac Sign should have been part of the horoscope since 1970 when Stephen Schmidt proposed it. However, since the proposal was questionable, they opted to stick with the 12 Zodiac Signs that the people already knew until NASA brought it back for the revised 2016 Zodiac Signs.
