If you have been feeling like your horoscope has been off lately you might be on to something. It is being reported today (and apparently for years) that NASA has added a constellation to the constellation chart which now means there are 13 astrological signs not 12, but are there really? This new constellation "Ophiuchus" is a result of the earth's shift over the last few thousand years. However it has always been there in the sky just not in "the orbit."

So let's welcome a "new" constellation that has always been there Ophiuchus. Which falls between Scorpio and Sagittarius on one of the Zodiac Chart. Adding the 13th sign has caused a shift in the Zodiac Calendar so you might want to check your birthday before some one asks you your sign.

NASA wants to make it clear that they are reporting astronomy not astrology. That they have not actually made changes to the zodiac because they aren't in the business of astrology. They are astronomers and they just did the math.

What's in a definition. Astrology according to Merriam - Webster is the study of how the position of the stars and the movement of the planets have a supposed influence on events and on the lives and behavior of people. Astronomy on the other hand is the scientific study of stars, planets and other objects in outer space.

So check out this new chart by NASA and see if you fall under a new sign.
