Hubble's sharp vision uncovered a never-before-seen dwarf galaxy located far behind the cluster's crowded stellar population. The loner galaxy is in our own cosmic backyard, only 30 million light-years away (approximately 2,300 times farther than the foreground cluster).The object is classified as a dwarf spheroidal galaxy because it measures only around 3,000 light-years at its greatest extent (barely 1/30th the diameter of the Milky Way), and it is roughly a thousand times dimmer than the Milky Way. Because of its 13-billion-year-old age, and its isolation — which resulted in hardly any interaction with other galaxies — the dwarf is the astronomical equivalent of a living fossil from the early universe.

I have a question about the picture of the universe they use. I understand it to be a 360 degree view from Earth or the hubble telescope laid flat pretty much, right? More or less?
Ok, when you get to the faintest dots, the furthest objects measurable, and into the black spaces between them, is the theory that there's more objects beyond this but they're too far for the hubble to see? Or that there's really nothing beyond that point that we know of? Because I remember reading that the hubble could see all the way back to the early days of the universe.

So what's the big deal that someone found one more?
Exactly. Let's see. Three thousand light years away. That means if we started traveling to it tomorrow, it would take us roughly... forever to get there.
