The bright star Eta Carinae, seen above with its surrounding nebula in an undated picture, will most likely die in a brilliant blast known as a Type IIn supernova. A pair of these supernovae, found 18 billion light-years away, are now the most distant star explosions known, astronomers said in July 2009

By blending pictures of the deep universe, astronomers have found the faint light from two supernovae (http://science.nationalgeographic.com/science/space/universe/supernovae-article.html) that are now the most distant stellar explosions known. The supernovae happened so far away that their light takes billions of years to reach Earth

Being able to see such faraway objects could therefore open a new window onto the lives and deaths of the first stars formed after the big bang, nearly 13 billion years ago

"The ones that we've detected happened about 11 billion years ago, so you're getting close already," said lead author Jeff , an astronomer at the University of California, Irvine


Due to the expansion of the universe, the record-setting supernovae are currently 18 billion light-years from Earth
