Scientists observe superconductivity in meteorites
Scientists at UC San Diego and Brookhaven Laboratory in New York went searching for superconducting materials where researchers have had little luck before. Setting their sights on a diverse population of meteorites, they investigated the 15 pieces of comets and asteroids to find "Mundrabilla" and "GRA 95205"—two meteorites with superconductive grains

While meteorites—due to their extreme origins in space—present researchers with a wide variety of material phases from the oldest states of the solar system, they also present detection challenges because of the potentially minute measurability of the phases. The research team overcame this challenge using an ultrasensitive measurement technique called magnetic field modulated microwave spectroscopy (MFMMS). Details of their work are published in Proceedings of the National Academy of Sciences (PNAS). Saiba mais...
