SCP-1548: The Hateful Star
SCP-1548 is an optical pulsar in the Crab Nebula. Radio observations reveal that the star is accelerating towards the Solar System, and that it is pulsing in Morse Code. The first fully transcribed SCP-1548 message, translated from Russian and broadcast in three bursts, reads as follows: “I wake/I see all/And find it lacking”. SCP-1548 is currently moving at a rate of approximately 0.85c (2.55x108m/s). In its messages, SCP-1548 has displayed extreme hostility as well as knowledge which it should not have access to, e.g. “the coordinates of all SCP secure facilities.”
In accordance with new information, several Foundation articles have been updated. These include the following:
SCP-1959: The Lost Cosmonaut
SCP-1959 appears to be a white spacesuit, currently in orbit around Earth. It appears it may still be occupied and displays other anomalous properties. It may be connected with secret Soviet space missions.
I really recommend clicking through to the SCP wiki to experience the full creepy factor of this one.
(And to make it even creepier, let me direct you to this little wikipedia article about the real-life conspirace.)
