No, NASA Didn’t Change Your Zodiac Sign

The articles cited a page on NASA’s website that mentioned a 13th zodiac sign, Ophiuchus. The same webpage described how the positions of constellations have shifted, relative to the Earth, in the thousands of years since the Babylonians originally mapped out the zodiac.

According to NASA, these two tidbits are nothing new.

In its Tumblr post, NASA explains the origins of the zodiac, created more than 3,000 years ago. According to ancient Babylonian stories, the zodiac originally contained 13 constellations, including Ophiuchus. However, they chose only 12 constellations to fit their existing calendar, which had only 12 months.

“To make a tidy match with their 12-month calendar, the Babylonians ignored the fact that the sun actually moves through 13 constellations, not 12,” the NASA post explains. “Then they assigned each of those 12 constellations equal amounts of time.”

Meanwhile, the earth’s axis has changed position since Babylonian times, meaning it doesn’t point in the same direction it did 3,000 years ago.
