By blending pictures of the deep universe, astronomers have found the faint light from two supernovae 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." (source: news.nationalgeographic.com)
