On July 14, 2015, at 11:49 UTC, it [New Horizons] flew 12,500 km (7,800 mi) above the surface of Pluto, which at the time was 34 AU from the Sun, making it the first spacecraft to explore the dwarf planet.
Henry Hall, the 94-year-old lighthouse keeper, discovered that a spark, probably from a candle in the lantern, had flown up and ignited the top of the tower. As Hall looked up to throw a bucket of water on the blaze, a stream of molten lead from the roof poured down his face and throat.
