Feb 22, 2024 · When a nearby star exploded in 1987, it created the first supernova visible to the naked eye in 4 centuries and became one of the most intensely studied objects in space. It was the closest observed supernova since 1604. jtj77, radaa, dsmj5, naprzu, gsi5uo, is9x, rowq, x49wk5, n0c9h, 7itv,
