The Geology Museum at the University of Wisconsin in Madison is displaying several pieces of the spectacular meteorite that lit up the sky as it fell over Wisconsin last week.
The space rocks are believed to be the size of a small peanut and are covered with a black substance.
Scientific experts say the objects are definitely not of this earth.
"Until we look at more samples and are able to take some measurements, we won't know what kind of meteorite it is," Norika Kita, a meteorite expert at the university, told Space.com
More tests will be performed to discover how the rocks were formed and what they could possibly reveal about the solar system.
"The frequency of space debris entering our atmosphere that is large enough to generate a fireball is something on the order of once or twice a day," said Don Yeomans, manager of the Near-Earth Object Office at NASA's Jet Propulsion Laboratory in Pasadena, Calif.
"What is somewhat unique about this one is that it was witnessed by so many and captured on tape," he said. "Sounds like it was spectacular. I wish I had been there to see it, too."
