Item #: SCP-XXXX

Object Class: Euclid

Special Containment Procedures: Due to the physically occluded nature of SCP-XXXX from the vantage point of Earth, and the lack of sufficiently developed technologies to intercept its transmissions from such a vantage point, no locally-relevant containment procedures are necessary. No remote containment procedures are currently viable.

Description: SCP-XXXX was discovered during the flyby of dwarf planet Pluto on July 14, 2015 by the NASA New Horizons spacecraft, using a covertly installed Foundation radio frequency detection module (as utilized in monitoring for instances of SCP-2998. SCP-XXXX appears otherwise unrelated to SCP-2998). SCP-XXXX describes the origination and propagation of a data transmission appearing to ultimately originate from Pluto's interior. Information gathered from the module is insufficient in detail to pinpoint the exact location of a postulated source, if one specific emanation point does exist below the surface. The signal appears to meet and refract from a single location on Pluto's surface just under the barycenter1 of the Pluto system, reaching and thereafter casting from the far side of Pluto's surface2. Penetration of SCP-XXXX through Pluto’s structure should be impossible for most (if not all) of the frequencies it utilizes, but such signals appear to permeate unimpeded. SCP-XXXX is transmitted over a wide range of frequencies, changing to a new frequency once every five (5) repetitions of its message3. Other parameters which vary for each set of five (5) individual, identical transmissions (further referred to collectively as a "broadcast") include variable duration of the broadcast, duration of intermissions between broadcasts, and signal intensity. These parameters appear to be selected at random, but do not change within a given broadcast set once enacted. Quiet periods with no apparent broadcasts have been observed. It has been determined that, on occasion, transmission mediums have been identified to venture into atypical reaches of the electromagnetic spectrum, outside of familiar communication frequencies (such as radio waves). These include, but are not limited to, X-rays, microwaves, gamma rays, and the visible-light spectrum. As such, what at first appeared to be extended periods of silence were instead broadcasts transmitted in otherwise unusual sections of the electromagnetic spectrum. Thus far, the SCP-XXXX has not been observed to emit transmissions that use or combine more than one frequency band within any one broadcast.

SCP-XXXX has been determined to issue a string of numbers that appear to correlate to the approximate location of Earth at the time of broadcasting, through utilization of a novel spatial coordination grid based on the confines of the host body (Pluto)’s orbit, details of its traversal about the Sun, and Earth’s orbit. This information was made discernible through use of a cipher provided in the transmission, indicating that the contents of the broadcast were likely designed or intended to be interpreted by any entity capable of detecting and translating mundane broadcasts. SCP-XXXX then appears to issue details of a boundary surrounding Earth, as relayed by the instructed inversion of these coordinates that follow the first data segment of the broadcast. When plotted, these inverse coordinates designate an enclosed, spheroidal section of space encompassing the Earth-Moon System. Speculation regarding the intent or purpose of this message has led to several hypotheses, with the most prominent being that SCP-XXXX serves to indicate the anomalous conditions present within Earth’s vicinity. If this hypothesis is correct, it may suggest that the quantity or prevalence of anomalies on and around Earth, anomalies the Foundation has become accustomed to, are abnormal in relation to overall averages elsewhere in the universe. Alternatively, SCP-XXXX may instead be indicating Earth’s biological/human presence. These hypotheses are highly speculative. While broadcast signals are relatively weak and difficult to pick up, having Earth's presence exclaimed by SCP-XXXX has been deemed a sufficient risk, and plans to interrupt or otherwise stifle the broadcasts are currently awaiting approval. Research into decoding and interpreting the brief period during which broadcasts were within range of the New Horizons spacecraft is ongoing. Collected data is available to all researchers with Level 2 clearance and higher.

It is unknown by what means SCP-XXXX was integrated into Pluto, or if the signal is innate to Pluto itself. How long SCP-XXXX broadcasts have existed is also unknown.
