What the heck is in the air this past week? First we see a simulated image of the sky from Mars go massively viral because people thought it actually showed Earth in the Martian sky, then a clearly Photoshopped pic of two "Suns" setting on Mars gets passed around.
And now a new slice of oddness enters the field: a picture of a planetary alignment over the Giza Pyramids, saying this only happens once every 2737 years. Because planetary alignments and the pyramids play such a large role in New Age/astrological beliefs, there is clearly some sort of spiritual message implied here.
Well, I hate to be a thricely-bursting-bubble person, but here we go again, again. Let me be clear: while there will be an event more-or-less like this in December, and it should be pretty and quite cool to see, the claims being made are somewhat exaggerated. The picture itself isn’t real, and the planets won’t really look like that from Giza. Also, alignments like this happen fairly often, though to be fair getting them spaced out to fit over the pyramids in this way probably is relatively rare.
Busting your Cheops
Here’s the picture making the rounds:
It clearly shows the three pyramids in Giza, Egypt, with three planets above them. There are various versions of this picture I’ve seen; most are like this with almost no explanation. Some say the planets are Mercury, Venus, and Saturn, and some mention this is what it will look like on December 3rd, 2012, just before sunrise.
First, this obviously cannot be an actual photo if the event hasn’t happened yet! This must be a Photoshop job. That’s fine if it’s only to show what things are supposed to look like, and no one is claiming this is an actual photo.
However, it hardly matters. There are lots of other problems with this planetary alignment claim.
What’s your angle?
The first thing I did when I saw this was ask: is there really going to be a close conjunction of three planets on December 3rd?
The answer is yes! Mercury, Venus, and Saturn will all be within a relatively small distance of each other in the sky on that date. This isn’t a particularly tight configuration like Venus and Jupiter were earlier this year – in this case, they’ll be 14 degrees apart, nearly 30 times the width of the full Moon on the sky – but it’s still pretty nifty.
The second thing I did, though, was ask myself: will they really look like that in the sky as seen from Giza?
The answer this time is no. I used the software planetarium program SkySafari to show what the three planets would look like in the sky before sunrise on December 3rd as seen from the location of the pyramids, and got this:
In this picture, the yellow line is the ecliptic, the path of the Sun in the sky through the year. The green horizontal line is the horizon, and the three planets are labeled.
Note the angle of the planets: in the picture going viral, the planets are much closer to horizontal, but in reality the line connecting the planets is at a much steeper angle. It’s nearly vertical, in fact. This may not seem like a big deal, but having the planets closer to horizontal like in the viral picture is more spectacular than what will really happen, exaggerating the claim.
Not only that, but in the pyramid picture the planets are almost exactly on a line, like beads on a string. But as you can see in the picture above, they’re not nearly that colinear. Again it’s looking like the pyramid picture is exaggerating the situation.
I noticed something else funny as well.
