Planetarium The Rose Center for Earth and Space seems destined to become a major architectural landmark of New York. Here, ELT students are silhouetted against th bright daylight that illuminates it. The sphere of the planetarium, at left, serve as as a scale model for each of the different stations of the "Scales of the Universe" walkway that winds around it. For example, at the first station, a plaque roughly the diameter of a baseball stands for the Virgo supercluster of glaaxies that contains the Milky Way, and the sphere shows the observable universe to scale. Farther up, a small palque represents the local group of galaxies, and the sphere represents the Virgo supercluster, and so on. The walkway is visible at the far right.
