A space rock that yielded a startling sonic boom over South Texas in February is now on display at San Antonio’s Witte Museum as part of a meteorite-focused exhibit. The Witte’s new “Welcome to Earth” display showcases five separate meteorites, including the one that caused the boom heard across the Rio Grande Valley. Visitors will be able to look at the billion-year-old rocks and their crystals through a microscope and learn about how space enthusiasts and NASA scientists track the fragments down after they strike the planet’s surface.
