An Earth-threatening asteroid may be the last thing you want to see — unless it's in the confines of a museum. Today (Nov. 3), the Smithsonian's National Museum of Natural History revealed the first public display of a sample collected from the asteroid Bennu, which NASA deems a "potentially dangerous object."
The sample — 3.5 to 8.8 ounces (100 to 250 grams) of rocky space rubble collected by the OSIRIS-REx spacecraft — is thought to contain some of the earliest precursors to life and is the first chunk of a space rock ever grabbed by a NASA mission.
