Researchers used high-speed X-ray imaging at SLAC to reveal erased Greek text in a 1,500-year-old palimpsest, uncovering Hipparchus’ ancient star catalog with surprisingly accurate naked-eye coordinates.
Researchers at SLAC used synchrotron X-ray fluorescence to image a medieval manuscript and reveal erased coordinates from Hipparchus’s star catalog, recovering a highly accurate ancient sky map. The new data can be compared with Ptolemy’s preserved records to reassess attribution and potentially reshape debates about the origins of early astronomy.
