Two explosions observed in 2004 and 2006 in a galaxy 78 million light years from Earth were part of the fiery death of one of the most massive stars known to exist, astronomers said on Wednesday. Writing in the journal Nature, the scientists described the supernova death of a star estimated to be 50 to 100 times as massive as our sun in a galaxy called UGC4904 in the Lynx constellation. A supernova is a gigantic explosion that marks the demise of a star. The researchers said Japanese astronomer Koichi Itagaki discovered a faint celestial explosion that remained visible for about 10 days in 2004, then detected a second, much more powerful explosion two years later.
