Planetario de Bogotá

This guide to the Planetario de Bogotá opens on a Friday-night laser concert under its dome, then reaches back to the building's opening on December 22, 1969, under Mayor Virgilio Barco Vargas. You'll hear how Colombia paid an East German firm for its star projector in sacks of coffee, and why staff nicknamed the heavy, oddly shaped machine the ant. The guide follows that projector's decades tracing the sky before something newer took its place.
