A new observation of a "mystery" object was seen over a period of about three months recently from the Hubble Space Telescope. Now for some strangeness....
It was found outside any known galaxy seeming to mean it was kind of in the middle of nowhere.
It was of a different spectrum than all known or recorded supernova and, in fact, the spectrum was not found in the Sloan Digital Sky Survey database.
So what this really means is that some new class of celestial phenomena has been discovered. (Barring any discrepencies or scientific error). Everything new thing we find usually puzzles us even more, but they are certainly important in revising our understanding of the universe.
I was skeptical of this story originally, because it seems to be quite an anomaly on perhaps a grand scale. It hasn't yet been reported by NASA or any Hubble source that I've yet seen, but is published here.
And the technical report is here.
