The Hubble Telescope is sort of like our eye in the sky (except for the fact that is a telescope and not an eye and is in space). It's used to capture sharp images of the cosmos, which are then analyzed and scrutinized. It looks like the Hubble has managed to snap a shot of a previously undiscovered galaxy. Now, that normally wouldn't be big news, but there's a bit of a complication...
As far as we know, this galaxy shouldn't exist. At all.

And, if anyone is interested in getting a picture of the improbable galaxy up on their refrigerator...
Now, scientists have proposed something of a hypothesis to explain this galaxy's existence: it has a companion dwarf galaxy (scientists are evidently unaware that the polite term is "little person galaxy"), and the gravitational interactions between the two could have had a tremendous influence on its development. It's far too early to say for sure, but it's one possibility.
You know, this is what you just have to love about space. Every time we think we're just starting to get a handle on things, it throws us a curve ball. Who knows what we'll find next - another strange galaxy, or a glimpse into the gaping maw of Nyarlathotep, perhaps.
Damn, Space - you're incomprehensibly vast and still shrouded in mystery!
As far as we know, this galaxy shouldn't exist. At all.
This galaxy is so large, so fully-formed, astronomers say it shouldn't exist at all. It's called a "grand-design" spiral galaxy, and unlike most galaxies of its kind, this one is old. Like, really, really old. According to a new study conducted by researchers using NASA's Hubble Telescope, it dates back roughly 10.7-billion years — and that makes it the most ancient spiral galaxy we've ever discovered.
...The hallmark of a grand design galaxy is its well-formed spiral arms, but getting into this conformation takes time. When astronomers look at most galaxies as they appeared billions and billions of years ago, they look clumpy and irregular. A 10.7-billion-year-old entity, BX442 came into existence a mere 3-billion years after the Big Bang. That's not a lot of time on a cosmic time scale, and yet BX442 looks surprisingly put together. So much so, in fact, that astronomers didn't believe it at first, chalking their unusual observation up to the accidental alignment of two separate galaxies. But further investigations, conducted at the W.M. Keck Observatory in Hawaii, revealed BX442 to be the real thing.
