The only Star of David that can be seen from space?

Indeed. That's what Sohrab Ahmari is saying in Tablet Magazine.

There is quite possibly only one Star of David on Earth visible from space. Coordinates: 34.797924 N, 48.512927 E. Location: Hamadan, Iran.

Until just over a year ago, the Islamic Republic had hosted a second star: Israeli engineers commissioned by the shah in the 1970s to construct Iran Air headquarters in Tehran put an unmistakable Magen David on the roof of the airport building. But the discovery of the symbol by a Google Earth user in November 2010 scandalized the mullahs. An Iranian news site reproached Tehran’s municipal authorities for failing to remove “this Zionist star symbol, 32 years after the success of the revolution.”

More recent Google Earth images show that the airport star is now covered by black concrete. But the other Star of David—the one remaining in the western Iranian city of Hamadan—attests to millennia of shared Persian-Jewish history.
