The McMath-Pierce Solar Telescope

The world’s largest solar telescope, and the world’s largest unobstructed-aperture optical telescope with a diameter of 1.6 meters.

Permanent instruments include a dual grating spectrograph capable of extended wavelength coverage (0.3-12 microns), a 1-meter Fourier Transform Spectrometer for both solar and laboratory analysis, and a high-dispersion stellar spectrometer.

Chichen Itza, a UNESCO World Heritage Site, is the second-most visited of Mexico’s archaeological sites.  The archaeological site draws many visitors from the popular tourist resort of Cancún, who make a day trip on tour buses. In 2007, Chichen Itza’s El Castillo was named one of the New Seven Wonders of the World after a worldwide vote.

In the 1980s, Chichen Itza began to receive an influx of visitors on the day of the spring equinox. Today several thousand show up to see the light-and-shadow effect on the Temple of Kukulcan in which the feathered serpent god supposedly can be seen to crawl down the side of the pyramid.
