Dr. Amanda Kenson's scientific team has cataloged three major discoveries on the artifact encased in the 157-Golgotha asteroid. First, the large artifact is rooted into the core of the asteroid and has a barrier that is similar to but much more powerful than a biotic stasis field. This gives it an unnatural resilience to alteration or damage and even prevents state-of-the-art laser drilling from extracting the smallest piece for analysis.
Second, the object's interior is energetically active with a quantum stasis field rivaling that of Prothean technology found in mass relays. Like those creations, it activates in response to threat, at which point the artifact consumes a phenomenal amount of power. Dr. Kenson's team believes the object draws power directly from dark matter, though how is still unknown.
The third discovery is that the object broadcasts signals and information on many different spectra. One such pulse, suspected to be similar to a quantum entanglement communicator, reaches into Reaper territory. Another broadcast is infrasound, consistent with frequencies that trigger feelings of awe and fear in humans, a known factor in Reaper indoctrination. Kenson's laboratory is filled with equipment dedicated to monitoring any signal coming from the artifact in the hopes that some clue will prove the Reapers' undoing before it's too late.
