The most distant galaxies ever…

An eXtreme deep field Hubble image.



This image shows the position of the most distant galaxy discovered so far within a deep sky Hubble Space Telescope survey called GOODS North. The survey field contains tens of thousands of galaxies stretching far back into time.

The remote galaxy GN-z11, shown in the inset, existed only 400 million years after the Big Bang when the universe was only 3 percent of its current age. It belongs to the first generation of galaxies in the universe, and its discovery provides new insights into the early universe. This is the first time that the distance of an object so far away has been measured from its spectrum, which makes the measurement extremely reliable.

GN-z11 is actually ablaze with bright young blue stars, but these look red in this image because its light was stretched to longer, redder wavelengths by the expansion of the universe.

Alice: Would you tell me, please, which way I ought to go from here?
The Cheshire Cat: That depends a good deal on where you want to get to.
Alice: I don’t much care where.
The Cheshire Cat: Then it doesn’t much matter which way you go.8x10-print-alice-in-wonderland-cheshire-cat-smiling-famous-grin-victorian-era-42671f5a8f64a96a10a0f95cc1c928e1
Alice: …So long as I get somewhere.
The Cheshire Cat: Oh, you’re sure to do that, if only you walk long enough.
