CAPE CANAVERAL, Fla. (AP) — Death definitely becomes this star.Astronomers reported Wednesday on a massive, distant star that exploded in 2014 — and also, apparently back in 1954. This is one supernova that refuses to bite the cosmic dust, confounding scientists who thought they knew how dying stars ticked.The oft-erupting star is 500 million light-years away — one light-year is equal to 5.9 trillion miles (9.5 trillion kilometers) — in the direction of the Big Bear constellation. It was discovered in 2014 and, at the time, resembled your basic supernova that was getting fainter.But a few months later, astronomers at the California-based Las Cumbres Observatory saw it getting brighter.
