From Glamour.com apparently, NASA had to shake up all our lives because the Earth is a little different from the way it was back when the Babylonians created the zodiac we knew and loved. “Now, 3,000 years later, the sky has shifted because Earth’s axis (North Pole) doesn’t point in quite the same direction,” the NASA explanation says.

And in order to make their zodiac calendar seem perfect (12 month calendar, 12 zodiac signs, one sign for each month—you get it) the Babylonians straight up ignored a 13th constellation, and NASA has taken it upon themselves to set things right.
