He sent a request for ideas to an optical company called Carl Zeiss located in Jena. Engineers at the company decided to try light bulbs rather than holes for the stars. This would ensure a bright controllable light level even on cloudy days and during evening hours. There was a problem. A large ball in which up to viewers would stand and look at light bulbs would require a large noisy motor to turn the device. Also, the planets have variable positions.

Over the years the Adler's collection of historic instruments has grown, particularly under the curatorship of Marjorie Webster and the late Roderick Webster. The Adler was operated by the Chicago Park District until , when it incorporated as a nonprofit institution with its own board of directors. Paul Knappenberger arrived as president in , determined to move the Adler to the forefront of public education in astronomy.

And the science behind it is still precise today. How accurate? Look up, and every planet, star, sun and moon moves exactly as they do in reality, albeit reduced in scale by a factor of one trillion, meaning 1mm on the ceiling represents one million km. Jupiter takes 12 years to orbit the sun.

Saturn, 29 years. Even so, it is astonishing: a Baroque theatre for stargazers, crowning the living room of a modest wool comber who lived shortly after the Dutch Golden Age. All told, an unfathomable undertaking considering Eisinga quit school aged The Royal Eise Eisinga Planetarium, today an astronomy museum and centre for space exploration, has been drawing people from around the world ever since it opened in At certain times of year, Warmenhoven explained, he can see the sunrise above IJsselmeer bay when he crosses the Afsluitdijk causeway on his way to work.

Incredible, right?
