The world of astrology has erupted into total chaos, and it’s all thanks to NASA. The dates of the western zodiac calendar have suddenly compressed and shifted by weeks, so Virgos who were born before mid-September are now Leos — which, under the revised schedule, runs from Aug. 10 until Sept. 16.

In addition, there’s now a 13th sign called Ophiuchus, which applies to those born between Nov. 29 and Dec. 17. But why the sudden change? As it turns out, it all stems from a history of the western zodiac written by NASA back in January. It talks about the flawed history of the zodiac, and how the ancient Babylonians could track the sun through the sky but didn’t realize the reference point on Earth was unstable, as the planet doesn’t spit perfectly on its axis.

As Babylonian astrology depends on where Earth is located, and since the Earth’s poles have been moving at a rate of seven inches per week, by rolling back the clock it’s clear that zodiac fans are way off the mark.

Of course, don’t expect NASA to feel sorry for you: they remind readers that astrology is fantasy, not reality, and there job is to worry about science.

The NASA statement adds: “The constellations are different sizes and shapes, so the Sun spends different lengths of time lined up with each one. The line from Earth through the Sun points to Virgo for 45 days, but it points to Scorpius for only 7 days. 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. Then they assigned each of those 12 constellations equal amounts of time. Besides the 12 familiar constellations of the zodiac, the Sun is also aligned with Ophiuchus for about 18 days each year.”
