Ok, so... weird shit has been happening in Elite the past few months, things that seem to point to an alien presence.
A quick rundown on aliens in the Elite universe: Extraterrestrial life does indeed exist in the universe of Elite. But it is very rare, and typically pretty simple. While there have been planets discovered with life on them, that life is almost always very simple single-cell organisms. I myself was pretty stoked to discover a gas giant that had life in the form of ammonia-based protoplankton floating around in the clouds.
Sentient life in the universe... that's another story. While life in the universe is there, but rare, sentient life is almost unheard of. There is at least one known sentient race to have existed outside of humans, as ruins with pictographs were discovered in the Soontill system, though the planet they were discovered on is long since dead.
And then there's the Thargoids. The Thargoids are rumored to be an extra-dimensional race of space faring aliens that live somewhere beyond our universe, in hyperspace. As hyperspace technology advanced, more and more odd occurances would happen, strange encounters during hyperspace jumps with ships experiencing something 'attacking' or 'pulling' them out of hyperspace. Strange sights, strange sounds (which shouldn't be possible in space, but that is a part of the mystery) to the point where some oldtimers even refer to hyperspace as witchspace, believing that it holds unknown horrors. There was a brief but violent encounter between the Alliance (the smallest of the three galactic superpowers) and what appeared to be an alien race coming from hyperspace, henced dubbed the Thargoids, that appeared in insect-like ships with no apparent propulsion system to attack, before vanishing without a trace. Even those that were shot down left behind no wreckage, so whether or not the alliance is believed in this encounter is iffy.
That brings us to now. As I said, strange things have been happening in the galaxy. Shipwrecks discovered with badly corrupted logs that seem to point to being attacked in hyperspace, which should be an impossibility. Mentions of strange 'sounds' coming from weird objects. Even a whole space station, being transported via hyperspace to a new location, managed to go missing, and wasn't discovered until some time later a full 22,000 lightyears away from where it was supposed to be.
Strange objects, which have been named "unknown artifacts" have been discovered, seemingly alien in design. No one knows what they do, but they will scan your ship, emit a strange chittering sound (and again, no one is certain just how they are emitting what we perceive as sound while in space) and will badly corrode your ship should you try to scoop it into your cargo hatch, doing continuous damage until you eject it again. They also have a habit of causing technology around them to malfunction and shut down, which was discovered when players began amassing them within space stations, only to find the station soon shutting down from unknown causes.
This brings us to the newest discovery. Objects similar to the UAs but different in design, which have been dubbed Unknown Probes. These probes are even more rare than the UA's, and people are in the process of researching them. One person discovered that scanning them with a discovery scanner will cause the probe to emit an EMP pulse that will temporarily shut down your ship, making you unable to scan it, and will also cause your ship to resonate with a strange sound. This person recorded that sound and ran it through a spectrograph, and was surprised at what they found.
There appears to be an image encoded within the sound.
This is now what everyone is trying to decipher. So far it is believed that it is a description of a specific planet or moon, though as to which planet that is still unknown.
As for me, well...
