Great experience! First they told us how Inca civilization was nurtured using the position of the sun. Then they showed us some Inca understanding of the Milky Way and Constellations. Finally took us outside to look at the stars with a telescope. Staff are friendly and can answer any questions you ask. One of the questions is that the names of the stars are all in English, some of which are somewhat strange to me as I am Chinese and only know Chinese names. Maybe next time you can add some Chinese names to the PPT.
