...supernova it was, a massive star dying in an explosion so violent that for a few weeks it will outshine hundreds of millions of stars put together. Its home, the Large Magellanic Cloud, is a satellite galaxy, or island of stars, that lies just beyond the fringes of our Milky Way galaxy, some 170,000 light-years from earth.
