This is exactly why we send astronauts to risk their life to service Hubble: in a paper published last week in the Astrophysical Journal, scientists detail the discovery of a new unidentified object in the middle of nowhere. I don't know about you, but when a research paper conclusion says "We suggest that the transient may be one of a new class" I get a chill of oooh-aaahness down my spine. Especially when after a hundred days of observation, it disappeared from the sky with no explanation. Get your tinfoil hats out, because it gets even weirder.

Apparently, a scientist at the LHC declared that the object is similar to the flash that an Imperial Star Destroyer does when reaching Warp 10. Either that or some dust on the Hubble lenses, so someone tell NASA to get some Windex up there too.
