THE SCIENCE

 

 

 

A Galaxy of Suns operates using data from the Hipparchos astronomical catalogue, a high-precision data set collected by the European Space Agency’s Hipparchos satellite, which orbited the Earth between 1989 and 1993.  It remains the most accurate listing of stellar positions to date, containing detailed information about over 118,000 stars.  Only around 5,000 of these stars are visible with the naked human eye, all existing within the Milky Way.  A Galaxy of Suns illuminates these cosmological objects, day and night, connecting audiences with otherwise invisible motions of the galaxy. 

 

Custom astronomical coding enables A Galaxy of Suns to calculate accurately to 1,000th of a second the exact time and location of star rises and sets for 360 degrees of the horizon - anywhere on the surface of the planet.
