Here is something fun. Sky and Telescope reports that the Hubble has spotted an unidentified object out in the far reaches of space.
What’s its distance? That would certainly be a first step to figuring it out, but only the broadest constraints can be put on its distance. Its lack of parallax motion means that it can’t be closer than about 130 light-years, and a lack of cosmic hydrogen absorption in its spectrum means that it can’t be farther than 11 billion light-years (when “distance” is defined by light travel time). That leaves a lot of leeway.
Wasn’t it our very own Sean who was speculating that all we need to do to attract the attention of the transdimensional gods is to muck around with, say, 5% of the known universe? Or was it Stuart? (I know, I know — that dot is a lot less than 5%. But it sure sounds interesting) (via Gizmodo)
