The glass cube on 81st Street with the great sphere floating inside, the spiral walkway of cosmic time, the planets on their orbits, the works on the balconies at every level.

The Rose Center for Earth and Space opened in February 2000 on 81st Street, designed by James Stewart Polshek's firm. An 87 foot sphere holding the Hayden Planetarium floats inside a glass cube. The original Hayden Planetarium had opened on the site in 1935.

The six storey glass cube, the eighty seven foot sphere held in its cradle, the ramp spiralling round it, the scale models of planets hanging in the void, the granite terraces outside, the night lit interior.

The room is an interpretation, and it hangs the New Yorkers the census recorded at this place first.
