This is the oldest object we've found yet in space. It's a galaxy whose light traveled more than 13 billion light-years before it was visible to Hubble. And it's only 600 million years younger than the universe itself.
What you're looking at above is an artist's rendering of UDFy-38135539, the most ancient space object we've been able to locate to date. It's so far away that even to Hubble's powerful lens it appears as not much more than a speck:
It's about 160 million years older than the previous oldest galaxy, which was found back in 2006. The most exciting part? Astronomers speculate that the oldest galaxies formed as early as 200 million years after the Big Bang, meaning we've got a whole lot of discovering still ahead of us. [Discovery via Geekologie]
