Today's photo-of-the-day was taken on the street outside the Observatory of Ulugh
Beg in Samarkand, Uzbekistan. According to Wikipedia, "Ulugh Beg, the son
of Shah Rukh and grandson of Amir Timur, became the ruler of Samarkand in the
15th century AD. Ulugh Beg was very skilled in mathematics and
astronomy...[The observatory] could accurately measure the sun from the
horizon, the altitude of a star and other planets. The duration of the year,
period of planets, and eclipses were measured by this device. Ulugh Beg's
measurements of planets closely relate to today's measurement."
Oh, the photo. It shows, not a model of Saturn's rings, but freshly
baked bread offered by a street vendor outside the observatory.
A bonus photo of the observatory itself is after the jump.
