Luna flew about the sky, guarding the night over Equestria, noticed something unfamiliar in the sky, something that looked Alien. She had used her power of the night to draw this object down from orbit for a second look. It was a Structure Composed of a Gold metal, hexagonal main body, with a thin, large bowl shape at the top. In the center of the bowl, a small radio antenna lie. There were also longer antennas on the sides, 3 of them to be exact. The other side had a Small, golden truss beam, with several radio instruments on it. On one of the sides, like a Large, golden disk with several alien markings on the front. Luna flew it back to the main Canterlot castle and informed her sister for a closer inspection.
