Touching the Sun with Solar Stones

In August 2024, the Heliophysics Big Year theme is Back to School. In collaboration with NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission and the Colorado School for the Deaf and Blind, Creative Technology and Design students at the ATLAS Institute at University of Colorado Boulder have developed tactile representations of what many scholars believe to be the earliest known record of solar observations. 

Titled “Solar Stones,” the exhibit displays two famous petroglyphs, or rock carvings, found in Chaco Culture National Historical Park located in northwestern New Mexico. One petroglyph is believed to represent a total solar eclipse occurring on July 11, 1097, and the other a solar marker that indicates the annual equinoxes and solstices. The project is on display at Fiske Planetarium located on the University of Colorado Boulder campus.
