Following a small meteor shower near his Lunar base,
Professor Zack Zapperoni was conducting an external examination of damage when he discovered a strange glowing substance covering a rock formation close to the main dome wall. When he moved towards the substance it seemed to react to his presence.
Using his exosuit sensors the Professor conducted a short analysis of the substance. He was surprised to discover that along with the Tungsten, Tantalum, Gallium, Silicon and Lawrencium his systems recognised, the vast bulk of the mass was made up of what seemed to be an as yet undiscovered heavy element.
Due to this unknown element and the strange reaction to his proximity, the Professor used a remote controlled S.T.A.S.H. (Subspace Transportation And Storage Handler) to collect the specimen safely and move it into his laboratory for further study, cataloging his find under the rather unimaginative name of Specimen #2780.
