>Pretty coooooool:

>Astronomers tracking a mysterious blast of energy called a gamma ray burst said on Tuesday they had snapped a photograph of the most distant object in the universe -- a smudge 13 billion light-years away.
>
>Hawaii's Gemini Observatory caught the image earlier this month after a satellite first detected the burst.
>
>"Our infrared observations from Gemini immediately suggested that this was an unusually distant burst, these images were the smoking gun," said Edo Berger of the Harvard Smithsonian Center for Astrophysics.
>
>Distortions in the light signature of the object show it is 13 billion years old -- at the speed of light, 13 billion light-years away. A light-year is 6 trillion miles (10 trillion km).
>
>This makes it easily the most distant object ever seen by humanity, Berger said.
>
>Gamma-ray bursts are luminous explosions that mostly occur when massive stars run out of fuel and begin collapsing into either a black hole or a neutron star.
>
>"I have been chasing gamma-ray bursts for a decade, trying to find such a spectacular event," said Berger. "We now have the first direct proof that the young universe was teeming with exploding stars and newly-born black holes only a few hundred million years after the Big Bang," he said.

Far out.
