Announced in November 2012, the Hubble Space Telescope has imaged the most distant galaxy ever seen. MACS0647-JD is 13.3 billion light years from us and we see it as it shone only 400 million years or so after the big bang. As scientists would expect with such a young galaxy, it is tiny compared to the size of our own galaxy.
