In appearance it is just a stain in space, but a unique stain. It has been found by Harvard astronomers while tracking a mysterious energy blast from Hawaii's Gemini Observatory. His surprise was to identify the trail of an unusually distant outburst 13 billion light-years away . "This makes it the most distant object ever seen by humanity, " said astrophysicist Edo Berger, co-author of the discovery.
Gamma ray bursts are light bursts that mostly occur when the core of huge stars collapses, turning into a black hole or neutron star. Specifically, the explosion occurred when the universe was 5% of its current age. The new finding, Berger says, is "the first direct proof that the young universe was fertile in star explosions and new black holes just a few hundred million years after the Big Bang."
