One of these gleaming monsters -- 10 times more massive than the sun -- violently self-destructed after presenting the cosmos with a final, radiant beacon of starlight.
..Jacobson-Galán is the lead author of a paper published Thursday in The Astrophysical Journal that documents the star's eruption as well as its last, 130-day hurrah....
