Neil deGrasse Tyson and friends gush over today's Pluto flyby
At around 7:50AM Eastern this morning, NASA's New Horizons probe reached its closest point to Pluto, around 7,750 miles away, where it unleashed its full array of equipment to give us our best look yet at the dwarf planet. It's the culmination of a nine-year journey across more than 3 billion miles -- and the scary thing is we won't even know until tonight if it succeeded. To celebrate the occasion, we joined Neil deGrasse Tyson, his colleagues and a theater full of science geeks at the American Natural History Museum to explore what the New Horizons mission really means. You can check out the full session, as well as some highlights from the event, below.
