Nearly a decade ago, NASA launched its New Horizons spacecraft into space, tasked with exploring our vast solar system and sending information home. After over three billion miles of flight, it has finally reached its ultimate destination: Pluto. Until now, details of the controversial dwarf planet have only been speculative—often describing it as oblong and gray—but information from New Horizons’ up-close encounter tells a different story. Pluto’s atmosphere reeks of nitrogen, its polar caps are especially icy and its red-brown landscape is marked with a mysterious and sweet heart shape.
