Because NASA studies astronomy, not astrology. And they wanted to remind us of that.

Long story short: when the ancient Babylonians divided the zodiac into 12 signs, they represented each sign with a constellation. Unfortunately, by the time they had set up the calendar, they realized that there were actually 13 constellations, not 12. So, they just ignored the 13th constellation: Ophiucus.

Because the Earth's axis has changed a bit over the last 3,000 years, NASA has decided to reveal what the zodiac really should look like. But they say that it's not their fault - you can blame the Babylonians for this.

What it really means is that a LOT of people are going to be doing one of two things: 1) getting their Zodiac sign tattoos covered up, or 2) not giving a damn about the change.

Because let's be honest - NASA doesn't care, either. They think astrology is BS anyways.

I'm now a TAURUS? Get the heck outta here.
